Patent number: 5099120Abstract: In a thermal-radiation detection system, the thermal radiation (3) incident on a group of pyroelectric and/or ferroelectric infrared detector elements (20) is modulated at a frequency (f). The detector elements (20) are mounted on flexible platform areas of an insulating substrate (10) which may be of an elastic material such as a silicone rubber in, for example, an apertured or recessed mount (18,19). The grooves (15,16) forming the platform areas have a sufficient depth d and width w that the distance (2d+w) is at least as large as the thermal diffusion distance at the modulation frequency (f) so as to reduce thermal cross-talk between the detector elements (20). The elasticity and vibration absorption properties of an elastic substrate (10) and the flexibility and path length increased by the presence of the grooves (15,16) can provide a low microphony mounting arrangement with acoustic decoupling between detector elements (20).Type: GrantFiled: June 19, 1990Date of Patent: March 24, 1992Assignee: U.S. Philips CorporationInventor: Andrew A.

Patent number: 4704534Abstract: A thermal radiation detector comprises detecting means supported by a flexible film.To improve the absorption of incident radiation by the thermal radiation detector, the detector comprises an electrically resistive layer which is immediately adjacent the flexible film, and to which the detecting means are thermally coupled. The optical thickness of transparent dielectric material preceding the detecting means (suitably consisting only of the flexible film) is one fourth of a selected wavelength in a given wavelength range to be detected. The wavelength is selected so that the absorption of incident radiation by the resistive layer is substantially a maximum at the selected wavelength. The resistive layer may be between the flexible film and the detecting means, or it may precede the flexible film. In the latter case, an electrically conductive, reflecting layer is disposed between the flexible film and the detecting means.Type: GrantFiled: March 3, 1986Date of Patent: November 3, 1987Assignee: U.S. Philips CorporationInventor: Andrew A.
