摘要：
The present invention refers to a skin or hair treatment device for emitting intense light radiation with an integrated sensor. The device has a housing； a treatment light source, wherein the treatment light source comprises an array of a plurality of light emitting elements arranged on a substrate； a sensor system, said sensor system has at least one sensing light source for emitting sensing light and at least one light sensor for detecting the sensing light, wherein the at least one sensing light source and the at least one light sensor are directed towards a device treatment window； and a control circuit having a processor. The device further has a circular polarizer interposed between the device treatment window and the at least one sensing light source and the at least one light sensor； and a shielding interposed between the at least one sensing light source and the at least one light sensor.
