Paper Abstract

The design and development of a new, flexible, linear array readout integrated circuit (ROIC) for a new family of linear array detectors are described in this paper. The detector technology used is based on indium-gallium-arsenide (InGaAs) and includes low dark current versions with room temperature wavelength response cutoff of 1.7 microns and versions with altered stoichiometry to shift the room temperature absorbance cutoff wavelength to 2.55 microns. Discussion includes choice of features to cover many applications, testing methods, and evaluation of the first versions produced. The result will be a highly flexible linear array family, with versions matched to biological imaging, hot process inspection, pharmaceutical pill inspection, agricultural sorting and contaminant rejection, plastics recycling, moisture monitoring of continuous web processes.
