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...
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. Microwave Opt Technol Lett 46: 78–80, 2005; Published online in Wiley InterScience (www.inters...
متن کاملMosaicked Multispectral Focal Plane Arrays
A mosaicked sensor is a monolithic array of many sensors, arranged in a geometric pattern. In the commercial digital color camera market, the mosaicked color filter array (CFA) technique is widely used, in which instead of using three charged coupled devices (CCDs) to capture the red, green, and blue spectral bands for each pixel, each pixel is associated with just one device covered by an opti...
متن کاملOptical Detectors for Focal Plane Arrays §
The paper presents progress in optical detector technologies during the past 25 years. Classification of two types of detectors (photon detectors and thermal detectors) is done on the basis of their principle of operation. The overview of optical material systems and detectors is presented. Also recent progress in different technologies is described. Discussion is focused mainly on current and ...
