12586 Final Art 2 5/9/01 4:51 PM Page 1 DATASHEET Lighting Imaging Telecom Imaging Product Line ® LC3000-Series High Performance, Low-Cost Analog Line Scan Camera 512, 1024 and 2048 elements, 10 and 20 MHz output rates Description In the LC3000-series analog line scan camera, PerkinElmer has combined the best features of photodiode array detection, high-speed charge-coupled scanning, and analog line scan camera technology to offer an uncompromising solution to the increasing demands of advanced imaging applications. The LC3000-series is a high performance, low-cost, analog line scan camera line. The LC3000-series features a differential driver analog video output with resolutions of 512, 1024 or 2048 pixels, which can achieve data rates of up to 20 MHz with exceptional noise immunity. They are designed for volume applications where small size and low cost are required. In order to allow the user to compensate for variations in illumination found in "real-world" application environments, the cameras feature adjustable gain and offset levels. The LC3000-series cameras feature a geometrically precise photodiode CCD image sensor with 14µm square photoelements. State of the art electronic design enables the LC3000-series to deliver consistent, reliable performance while the sturdy metal housing provides maximum protection in a variety of harsh environment and factory floor conditions. The LC3000-series cameras convert light imaged during a scene into an analog video signal. The amplitude of the video signal is a linear function of the incident illumination taken from the scene. Antiblooming structures within the sensor ensure superior performance over a wide range of lighting conditions. User-defined control is possible for line rate, integration time and video data rate. LC3000 cameras may be interfaced to most frame grabber cards, allowing for a tested, plug and play solution.

Each photodiode converts incident light into discrete charge packets. Advantages of pinned photodiode pixels include linear exposure control, the elimination of image lag, and the reduction of photo response non-uniformity (PRNU). For more specific sensor specifications and information, please consult the appropriate sensor datasheet.

The video channel signal processing circuitry offers both adjustable gain and offset levels to allow customization of the camera to unique lighting applications. An operational amplifier in a differential configuration is recommended to receive the video signal. Figure 2 details the camera video processing.

Master mode is to be used when the LC3000series camera is operating as a standalone unit. Master mode requires only input DC power (12-24 VDC) for operation. In this mode of operation, the camera will operate at its basic clock frequency (defined by the model number) and at the maximum line rate. Master mode operation is selected using the bank of rear-camera located Wavelength (nm) Table 1.

These switches are accessible behind a removable panel, located above the 25-pin connector on the back plate of the camera. Figure 3 illustrates the timing details in Master Mode. Slave Mode is to be selected when the camera’s operations are to be synchronized with the user’s unique system. In slave mode, the camera requires an external Master Clock signal (MLCK) to define the output video data rate, as well as a properly timed Line Transfer (LT) signal to initiate the line readout. Figure 4 illustrates timing details in slave mode. Table 1 details correct DIP-switch settings for both Master and Slave Mode. Within slave mode, there are two alternative settings for unique applications. Alternative Slave Mode 1 allows the user to supply the camera with Line Reset (LR) and LT signals, but allows the camera to run at the maximum data rate determined by the internal oscillator. Alternative Slave Mode 2 instructs the camera to ignore LR signals, which allows users to bypass the exposure control feature of the camera.

An internal oscillator sets the default data output rate to default model rate (10 or 20 MHz), and the camera will operate at the maximum line rate. The camera can be further controlled by three externally generated differential input signals: Master Clock (MCLK), Line Transfer (LT), and Line Reset (LR). The Master Clock input determines the data rate frequency for values up to maximum clock of the camera. The MCLK input is optional, as the camera is preset to run off of the internal oscillator at the default maximum data rate. Should a data rate slower than that default rate be necessary, an externally supplied master clock can be enabled by selecting that setting through the bank of DIP-switches. The data rate may be run from 20 kHz to cameras maximum clock rate. External line transfer operation also can be enabled on the DIP-switch bank. The Line Transfer input signal transfers the charge from each photo site to the readout registers. The readout registers, in turn, transport the charge from each photodiode in succession to the video outputs. The LT input from the user must remain in the ON state for at least two MCLK cycles to initiate the internal line transfer and may remain ON until 2 clock cycles prior to the next desired line transfer. Because there are extra stages in the CCD sensors readout register, a minimum number of MCLK cycles (the number of elements on the CCD sensor plus 41) must exist between successive LT commands. The maximum line scan period without exposure control is 20 milliseconds. Integration times longer than 20 ms can introduce higher levels of dark current, which reduces the dynamic range of the sensor. Longer integration times are possible, however, if the camera is cooled, which reduces dark current. Specific application characteristics, such as light level and rate of object motion, will determine the optimum setting. Exposure time of the Table 2.

The LR input is active low (ON) in polarity and therefore, when not in use, must be held high (OFF). In this condition, the exposure time is defined by the period of the LT signal. When using the LR input signal, the exposure period is defined to be the time between the rising edge of LR to the rising edge of LT. The LR signal must be held active low (ON) for a minimum of 4 clock cycles and must be inactive high (OFF) for a minimum of 4 clock cycles prior to the LT signal. of the CCLK signal can be used to capture analog video data by a frame grabber or digitizer. The Line Enable (LEN) signal brackets the valid analog video. The signal becomes high one CCLK period before the first valid pixel and goes low one CCLK period before the last valid pixel. The video output is a contiguous pixel data stream with a dynamic range (defined as peak video divided by rms. pixel noise) of greater than 500:1. The Camera Line Transfer (CLT) output signal is an internally generated sync signal. Its falling edge indicates the start of a line readout sequence. This signal may be used for controlling strobes, shutters or other accessories of the users system. Output Signals The LC3000-series camera provides three output synchronization signals: Camera Clock (CCLK), Line Enable (LEN), and Camera Line Transfer (CLT). The Camera Clock (CCLK) operates at either the MCLK frequency or default camera frequency, and is synchronized to the analog video.

This offset is controlled by the bank of DIP-switches. Table 2 describes the nominal level of the video black level with respect to the various switch selections. Additionally, the LC3000-series cameras feature a user-adjustable video gain. Video gain is adjustable by the bank of DIP-switches.

The sensor is mounted on an aluminum plate that efficiently transfers heat to the camera case. The camera is provided with a standard 1 /4"-20 UNC tripod mounting block, which can be attached to any of the four sides of the camera. The mounting holes used to attach the tripod block can also be used to mount the camera assembly. The recommended mounting method for the LC3000series is attaching the camera to the desired location using the faceplate of the housing. The faceplate mounting screws should have a maximum insertion depth of 0.25" (6.35 mm). This mounting method results in the most advantageous use of the one-piece faceplate design and provides a highly stable reference surface to the optical plane of the CCD sensor. Additionally, the CCD sensor is thermally coupled to the faceplate of the camera, and the conductive cooling of this surface is useful in minimizing thermally generated dark current and noise of the camera system.
