Abstract

A practical technique is described for defining with high precision the active area of each element of an array of pyroelectric detectors when these detectors are required to be of small dimensions, closely spaced and separated from each other by complete reticulation. The technique makes use of a thin film array of. IR absorbing elements with the required active area and thermally coupled to a corresponding array of pyroelectric elements, each of which has an area less than the active area and requires a relatively low dimensional to4erance. A design is proposed which is suitable for chopping frequencies approaching 103 Hz.
