The performance of liquid nitrogen (LN2) cooled digital scientific instrumentation camera incorporating a large format (512 x 512, 2 0.3 mm diagonal) Charge Injection Device (CID) imager which was fabricated by CIDTEC for use in low-light imaging applications is described in this thesis. The LN2 cooled camera outputs 14 -bit digital pixel data which can be read out randomly and non-destructively from individual pixels, multiple sub-arrays, or from the entire imager. CID's have the unique capability to skim accumulated pixel charge and/or non-destructively read pixel information, enabling the system user to monitor events and dynamically adapt application exposure in real-time for the entire array or individual pixels. Non- destructive read-out also is used to extend linear dynamic range. The Intel8 80286 based camera system operates from PC/AT compatible platforms through a digital I/O board. Topics in this thesis include the CID camera system overview, mechanical and electronic components, dewar cooling, system calibration, programming of the driver software and final performance evaluation of the system.
