Abstract

930,712. Photo-electric devices. MINISTER OF AVIATION. Nov. 30, 1961 [Dec. 1, 1960], No. 41315/60. Class 37. [Also in Groups XX and XL (b)] The invention relates to an infra-red radiation detector of the photo-resistive type, comprising a photo-sensitive element in combination with a tunable band-pass filter to reject background radiation, parts of the detector being arranged to be cooled below room temperature during operation, both the element and the filter being in contact with the cooled part. As shown, an element 1 of germanium or indium antimonide is mounted on a hollow column 2 of a glass container 3 and has secured to it one, 6, of a pair of Fabry-PÚrot plates 6, 7 which act as a band-pass filter, the other plate 7 which faces an optical window 8 of the container 3, being mounted at the end of a hollow nickel tube 9. Tuning of the filter is effected by passing current through a coil 10 encircling the container 3, thus causing the plate 7 to be moved by means of the magneto-striction action of the coil 10 on the tube 9. By tuning the filter over a band of frequencies, the. detector may be caused to act as a simple spectrometer. The column 2 may be cooled below room temperature by the use of liquid nitrogen.
