Paper Abstract

This paper discusses the design, architecture, and performance of a 6000 element Indium Antimonide Infrared focal plane array. The focal plane array architecture allows for any N x 1000 element sized array to be constructed from its base elements. A uniquely constructed bi-staggered detector geometry is utilized to provide 2:1 over-sampling having 10 micron effective pitch in both the across track and along track directions. Additionally, the detector geometry allows for physical pixel sizes up to 25 microns while sampling at a 10 micron effective pitch to provide alias free imaging with the high signal capture capability of a large pixel. The Indium Antimonide detectors are front-side illuminated P-on-N type mesa diodes having no measurable crosstalk. A complimentary CMOS based Multiplexor in a M x 250 segmented design having up to 10 million electrons full-well output with greater than 14 bits instantaneous dynamic range provides a flexible and low noise readout for the focal plane array. Hybridization of the Indium Antimonide detectors and multiplexor is provided via a Lockheed Martin patented beam-lead technology to provide reliable and producible long linear focal plane arrays for reconnaissance applications. Characterization of the 6000 element Infrared focal plane array is presented including dynamic impedance of the diodes, read-noise, linearity, and non-uniformity. Meadured characteristics of the CMOS multiplexor are also presented in addition to data from the hybridized modules making up the Focal Plane Array.
