Back Thinned CCD Devices

Hamamatsu Photonics introduce the S10200 TDI (time delay integration) sensor, featuring high speed, high sensitivity, back thinned CCD image sensors. The sensors have an option for 1024, 2048 or 4096 pixel length by 128 pixel height, 90% peak quantum efficiency to visible light, with high UV and near IR sensitivity. The series offer very high-speed data readout of 30 MHz per pixel, which translates to 50 KHz or 100 KHz line rates. Using the TDI image acquisition method, the system can synchronise charge transfer with the moving object, thus giving 128 times the image integration time of a conventional line sensor, and when combined with the high sensitivity of the back thinned CCD chip this results in an output two or three orders of magnitude greater compared to a regular line scan camera.
