128×128 infrared focal plane arrays based on Type-II InAs/GaSb superlattice

Radiometric characterization of type-II InAs/GaSb superlattice (t2sl) midwave infrared photodetectors and focal plane arrays

2048x2048 VISIBLE/INFRARED HgCdTe FOCAL PLANE ARRAYS (FPAs)

Rockwell has developed the world’s largest multiplexer for use with infrared HgCdTe and visible silicon detector arrays. The resulting FPAs are to be proposed for the Next Generation Space Telescope (NGST) program, ground-based astronomy, and other low background applications. The 2048x2048 multiplexer’s unit cell size is 18 μm x 18 μm with source follower per detector input (SFD) and 4 and 32 ...

Dual - Band Millimeter - Wave / Infrared Focal - Plane Arrays

In this paper, a novel arrangement for dual-band millimeter-wave and infrared focal plane array based on slot-antennacoupled metal-oxide-metal diodes is demonstrated. The receiving properties for millimeter-wave and infrared antenna-coupled detector pixels are presented. © 2005 Wiley Periodicals, Inc.

Preamplifier and AD converter system for infrared focal plane arrays

We describe a precision preamplifier and analog-to-digital ~AD! converter system for use with infrared focal plane arrays. The system uses a correlated double sampling integrated circuit which performs an analog subtraction of each full pixel level from its respective reset level prior to digitization by a 14-bit AD converter; this process is also known as ‘‘delta-reset’’ sampling. The system w...

Nonuniformity Correction Algorithm Based on a Noise-Cancellation System for Infrared Focal-Plane Arrays

In this paper a novel nonuniformity correction method that compensates for the fixed-pattern noise (FPN) in infrared focal-plane array (IRFPA) sensors is developed. The proposed NUC method compensates for the additive component of the FPN statistically processing the read-out signal using a noise-cancellation system. The main assumption of the method is that a source of noise correlated to the ...
