The design of instrumentation for remote sensing presents special requirements in the areas of power consumption, long-term stability, and compactness. At the same time, the high sensitivity and resolution of the devices needs to be preserved. This paper will describe several instruments suitable for remote sensing developed under the sponsorship of the Defense Threat Reduction Agency (DTRA). The first is a system consisting of a mechanical cryocooler coupled with a ...
While attempting to measure (mu)t products in HgI2 using the pulse rise time method a method based on the Hecht equation fundamental limitations of the Hecht equation were revealed These limitations restrict the equations utility even for the case for which it was originally developed, i.e. when carrier trapping occurs without de-trapping. The Hecht equation purportedly analytically characterizes the charge collection process under uniform field and permanent charged carrier trapping ...
