Abstract

An infrared detector cell includes a plurality of uniformly spaced linear segments, which make up an optical grating. Each segment is selectively doped across its width to form a photovoltaic diode. The linear segments are ohmically connected between electrical conductors to produce a single cell detection signal. The cell comprises a diffractive resonant optical cavity. An array of cells can produce an infrared image. Cell configurations are illustrated for receiving both single dimension and linearly polarized radiation and two-dimension unpolarized radiation.
