New High Sensitivity TDI Back-Thinned CCD Devices for High Speed Imaging Applications
12 Apr 2007
Hamamatsu Photonics introduce the new S10200 TDI (time delay integration) sensor, featuring the latest high speed, high sensitivity back-thinned CCD image sensors. The newly developed Hamamatsu CCD sensors have an option for 1024, 2048 or 4096 pixel length by 128 pixel height and have 90 % peak quantum efficiency to visible light with high UV and near IR sensitivity. The S10200 series offer very high-speed data readout of 30 MHz per pixel, which depending on the sensor, translates to 50 KHz or 100 KHz line rates.
Ordinarily high-speed imaging systems suffer from a lack of available light and special illumination systems need to be constructed. Using the TDI image acquisition method, the S10200 can synchronise charge transfer with the moving object, thus giving 128 times the image integration time of a conventional line sensor. When combined with the high sensitivity of the back-thinned CCD chip, it results in an output of two or three orders of greater magnitude compared to a regular line scan camera.
The features of this new CCD make it ideal for applications in low light level and high-speed industrial inspection, particularly where UV and NIR sensitivity are required. In particular the TDI CCD can be used for the inspection of mass produced consumer goods, such as flat panel and LCD displays, web inspection, electronic components and Pc-board inspection (AOI), biomedical instrumentation such as flow cytometry, postal sorting, high speed fluorescence imaging, semi-conductor inspection and many other in-line industrial applications.
