Line-scan Camera

NOW has designed all the electronics to a line-scan camera, four circuit boards. The CCD has eight outputs to eight A/D converters, each of these has a 30 MHz data rate, which gives 160 Mpixel/sec. The electronics includes an Altera Cyclone II FPGA programmed in the Quartus environment, and analog drive electronics for the CCD, a 2k x 96 TDI CCD. In order to get the best quality of the data from the CCD it must be controlled with precise analogue signals, with special rise and fall times, and signals therefore has a resolution of nanoseconds.
