Cidtec CID Video Cameras 

Charge Injection Device (CID) structure, principle of operation, and readout techniques are fundamentally different from Charge-Coupled Devices (CCD's). Each pixel in the CID array is individually addressed during readout. Scanning routines are implemented via electronic switching of row and column electrodes which are fabricated in a thin, clear polysilicon matrix over the surface of the array.  While CCD's transfer collected charge out of the pixels during readout ( hence erasing the image stored on the sensor), CID's do not transfer charge from  site to site in the array.

CID readout is accomplished by transferring  or "shifting" the collected  "charge packet" within an individually addressed pixel, and sensing displacement values across the electrodes at the site.  Readout is non-destructive because charge remains intact in the pixel after the signal level has been determined.  To empty the pixel for new frame integration, row and column electrodes are biased to "inject" the charge packet into the substrate collector.

Advantages for CID cameras over CCD cameras  

• CID's prevent blooming or streaking under extreme lighting conditions
• CID's can read multiple areas of interest within a given frame at higher rates for faster capture and processing
• CID's give UV response down to 185 nm and near-IR response without blooming, fringing or loss of data resolution.
• CID's tolerate high radiation environments.
