A process for making an infra-red detector array wherein an array of m * n first electrodes is formed on a substrate and a layer of plastic material having a polarization sensitive to infra-red radiation is deposited over the electrodes. The layer is partitioned into individual films each over an associated first electrode and second electrodes are positioned on the films on the side opposite to the associated first electrodes.

A thermal detector is made from a pair of electrodes and a plastic material disposed therebetween which material has a polarization sensitive to IR radiation. Preferably the detector is formed on a substrate with the plastic material being deposited by spin-casting. The material is a copolymer of TrFE and PVDF. The detector may be partitioned into an array of sensors and used in an apparatus wherein the image of an object is projected onto the array and a chopper is used to block the image from the sensors at regular intervals.

Spun cast IR detector arrays and method of making the same

A method and apparatus for mounting pyroelectric crystal elements and arrays on a molded plastic base. The molded plastic base includes a plurality of upwardly tapered plastic flexible legs which engage the pyroelectric crystal element or array at various points. The upwardly tapered plastic legs reduce to a nominal thickness of approximately 0.002 inches where they are fastened by epoxy onto the pyroelectric crystal element or array.

Pyroelectric crystal element and array mounting method

The apparatus is a pyroelectric detector array with an optical filter. A plurality of pyroelectric detector elements are arranged on a common substrate and an optical filter is placed immediately adjacent to the pyroelectric detector elements. The optical filter includes a plurality of filter elements, each with a preselected optical passband. The optical filter is arranged so that radiation incident on a pyroelectric detector element passes through a respective unique filter element.

Pyroelectric detector array with optical filter elements

An infrared detector capable of obtaining coincident fields of view of infrared radiation of different wavelengths is provided. The detector comprises a sandwich-type construction including PbSe and PbS photoconductive film layers.
