Review on Design & Testing of CCD Detector Data Generation & Acquisition System

Abstract

In this review paper, a CCD detector is used to capture the image of the object in dim level of light. The video signal coming from the detector is fed into the video processor which remove the intrinsic noise from the signal, a 0dB to 36dB PGA is inbuilt in processor which is adjusted by programming the PGA register and finally, convert the analog signal into digital by 12-bit ADC. The video processor consists the different kind of registers like control register, ADC register, PGA register, CLPDM, SCLK, OE register etc. These registers are need a clock pulse to perform the specific task and that clock pulse is generated in LabVIEW tool. A PXI card is used for data generation & Acquisition system. The generated clocks are passed to the video processor according to the pin configuration of video processor. Finally, a 12-bit of digital output is generated.
