Characterization of a Charge Injection Device Camera System for Spectrochemical Measurements.
Abstract
An electronic camera system employing a CID-11B Charge Injection Device (CID) detector is described. Unique capabilities of this camera system, including destructive and nondestructive readout modes, signal-to-noise enhancement through multiple nondestructive readouts, and pseudo random pixel addressing are discussed. The performance characteristics related to spectrometric applications are presented. Parameters discussed include sensitivity, linearity, noise, dynamic range, blooming, pixel crosstalk, and spectral response. The CID appears to be uniquely qualified among imaging detectors to fulfill those requirements for an imaging spectroscopic detector presented at the beginning of this manuscript. The sensitivity of the CID-11B has been shown to be very good over a wide spectral range. The effective readout noise can be made to be very low, and the device is not susceptible to readout lag or blooming. In addition, this device has a highly linear response function and, when operated at cryogenic temperatures, exhibits virtually no thermal charge generation. While the CID-11B does suffer from a form of spatial pixel crosstalk, this effect is both understood and easily compensated for.
