Infrared Detector Arrays for Astronomy
Use of infrared detector arrays in astronomy began roughly 20 years ago, and our detection capabilities in parts of this spectral range have doubled about every seven months since then. A variety of approaches are now used for detector arrays operating from 1 μm to 1 mm and beyond. They include direct hybrid arrays of InSb and HgCdTe photodiodes that operate from 0.6μm to 5μm, and of Si:As impu...
متن کاملHgCdTe Arrays for the Far
The development of focal plane arrays (FPAs) has dramatically increased the sensitivity and efficiency of large optical and infrared telescopes. For the 1-2.5 mm band, the 1Kx1K HgCdTe “Hawaii” chip is the largest operational array in astronomy. Similar arrays of 2Kx2K are now in development, with the goal of assembling an 8Kx8K mosaic array for the Next Generation Space Telescope (NGST) projec...
متن کاملCoherent Detector Arrays for Millimeter and Submillimeter Astronomy
Progress in many areas of astronomy requires large-area surveys and observations of extended objects. This includes the cosmic microwave background, nearby galaxies, the Milky Way, and regions of star-forming regions within our galaxy. The ability to carry out such studies is critically dependent on the development of affordable high-sensitivity focal plane arrays, for both spectral line and co...
متن کاملHgCdTe e-APD detector arrays with single photon sensitivity for space lidar applications
A multi-element HgCdTe electron initiated avalanche photodiode (e-APD) array has been developed for space lidar applications. The detector array was fabricated with 4.3-μm cutoff HgCdTe which covered a spectral response from 0.4 to 4.3 μm. We have characterized a 4x4 detector array with 80 μm square elements and an integrated custom cryogenic silicon read-out integrated circuit (ROIC). The devi...
متن کاملAnalysis of Crosstalk in HgCdTe based Vertical Photoconductive LWIR Detector Arrays
HgCdTe is a well known material for Infrared detection applications because of its special properties like high absorption coefficient, adjustable bandgap and moderate dielectric constant etc. Vertical PC detectors of HgCdTe are very easy to fabricate as compared to the other detectors with the desired uniformity and therefore, these detectors may be proved better choice if the cost and the yie...
