Optical sensor and detector for an optical detection

Abstract

The present invention relates to an optical sensor, a detector comprising the optical sensor for an optical detection of at least one object, a method for manufacturing the optical sensor and various uses of the optical sensor and the detector. Furthermore, the invention relates to a human-machine interface, an entertainment device, a scanning system, a tracking system, a stereoscopic system, and a camera. The optical sensor () comprises a layer () of at least one photoconductive material (), at least two individual electrical contacts (') contacting the layer () of the photoconductive material (), and a cover layer () deposited on the layer () of the photoconductive material (), wherein the cover layer () is an amorphous layer comprising at least one metal-containing compound (). The optical sensor () can be supplied as a non-bulky hermetic package which, nevertheless, provides a high degree of protection against possible degradation by humidity and/or oxygen. Moreover, the cover layer () is capable of activating the photoconductive material () which results in an increased performance of the optical sensor (). Further, the optical sensor () may be easily manufactured and integrated on a circuit carrier device.
