摘要： A sensor (1400) with radiation detectors (1421-1422) with two or more bolometer or photoconductor elements and bias polarity switching of one element to emulate mechanical chopping of input radiation. This electronic chopping permits higher chopping frequencies than mechanical chopping for bolometers because the scene settling time does not limit electronic chopping. The detectors may be within a single vacuum integrated circuit package with separate narrow passband filters for chemical spectral analysis.

摘要： A spectrometer (2500) including a detector integrated circuit (2501) which includes a linear array (2503) of 128 adjoining 2 by 10 superpixel bolometers in a package base (2530) and under an infrared transparent lid (2510) with a graded interference filter (2511). Filter (2511) has a rectangular shape and is a passband filter with a center wavelength which varies linearly along the direction of the long sides which is also the long direction of the linear array (2503) of bolometers. The center wavelength varies by a factor of about 2 over the length of the linear array (2503).

摘要： A quartz arsenic cell having a stabilizing valve used to generate hot arsenic vapor which is flowed into liquid gallium, to provide a melt of liquid gallium arsenide from which a crystal can be pulled. The stabilizing valve prevents negative relative pressure from occurring in the quartz arsenic cell, and thus prevents the molten material from being sucked back up into the quartz arsenic cell.
