Bandgap infrared radiation detector device used in thermal imager includes detector elements having linear dimensions which are each substantially smaller than the wavelength of the detected radiation

摘要

Infrared detector has electrically conductive elongate members comprising photosensitive segments separated by, but contacting non-photosensitive conductive elements. Electrically isolated, parallel conductive lines are positioned immediately above detector surface, and spaced apart by less than radiation bandwidth, for enhancing capture of infrared radiation.
