C4880-21

High Dynamic Range Streak Camera C7700 Less than 60 ps 10 000 :1 v The relaxation oscillation of a laser diode can be measured with the C7700 under single shot operation. (The data was captured with a C4880-21 readout CCD camera.) The C7700 is a newly developed high dynamic range streak camera that can handle a large number of photoelectrons. This feature enables single-shot measurements of ultrafast phenomena with a D-range as high as 10 000 : 1. This system is suitable for high-precision simultaneous measurement of high-intensity and weak intensity pulse light. High Dynamic Range Measure SYSTEM CONFIGURATION 3 Main Unit 1 Input Optics C7700 6 Readout Cameras Dual-Scan Cooled CCD Camera C4880-21 Camera head Control unit Frame Grabber Streak Image Analysis Software Streak Image Analysis Systems for IBM PC/AT 5 Output Optics Camera head ORCA2 Control unit DUAL MODE COOLED CCD CAMERA POWER Personal computer (IBM PC/AT Compatible) GP-IB board 7 Readout System (HPD-TA) Mount Table A7703 Trigger signal Sweep circuit Sweep electrode (where electrons are swept in the direction from top to bottom) 4 Image Intensifier, Image Booster Streak image [Operating Principle] The light pulse to be measured is focused onto the photocathode of the streak tube through the slit, where the photons are converted into a number of electrons proportional to the intensity of the incident light. These electrons are accelerated and conducted towards the phosphor screen, and a high-speed voltage which is synchronized to the incident light is applied. The electrons are swept at high speed from top to bottom, after which they are bombarded against the phosphor screen of the streak tube and converted to an optical image. When the light intensity of the streak image is very weak, an image intensifier or an image booster amplifies the low light level streak image.

With a light intensity, the image intensifier tube, such as an image intensifier or an image booster, is combined with a streak camera. In this case, the image intensifier tube may restrict the dynamic range of the measurement system. Furthermore, a read-out camera may also restrict the dynamic range of the measurement system.
