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 (110) comprises a layer (112) of at least one photoconductive material (114), at least two individual electrical contacts (136, 136′) contacting the layer (112) of the photoconductive material (114), and a cover layer (116) deposited on the layer (112) of the photoconductive material (114), wherein the cover layer (116) is an amorphous layer comprising at least one metal-containing compound (120). The optical sensor (110) 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 (116) is capable of activating the photoconductive material (114) which results in an increased performance of the optical sensor (110). Further, the optical…
