THz Imaging Using Uncooled Wideband Direct Detection Focal Plane Arrays
In millimeter and submillimeter-wave radiometric imaging systems, a persistent goal is the increase in the speed of acquisition of the image while maintaining a high sensitivity. Typically, the highest sensitivity is achieved by cryogenically cooling the detectors, specifically in astronomical applications. However, for the purpose of low-cost imaging applications, it is desirable to operate at...
متن کامل2048x2048 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 ...
متن کاملDual - 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.

متن کاملPreamplifier 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...
متن کاملUncooled IR focal plane arrays: worldwide review and state-of-the-art at ULIS
Uncooled infrared focal plane arrays are being developed for a wide range of thermal imaging applications. Developments are focused on improving the sensitivity to enable the possibility to manufacture high performance small pixel pitch detectors or radiometric detectors with internal “cold” shield. Commercial infrared is now a well-established business with several competitors. We review the s...
