  • Publication number: 20180224368
    Abstract: The invention describes a laser sensor module (100) which is adapted to detect or determine at least two different physical parameters by means of self-mixing interference by focusing a laser beam to different positions. Such a laser sensor module (100) may be used as an integrated sensor module, for example, in mobile devices (250). The laser sensor module (100) may be used as an input device and in addition as a sensor for detecting physical parameters in an environment of the mobile communication device (250). One physical parameter in the environment of the mobile communication device (250) may, for example, be the concentration of particles in the air (air pollution, smog . . . ). The invention further describes a related method and computer program product.

The laser sensor module (100) comprises at least one first laser (110), at least one first detector (120), at least one electrical driver (130) and at least one evaluator (140). The first laser (110) is adapted to emit first laser light in reaction to signals provided by the at least one driver (130). The at least one first detector (120) is adapted to determine a first self -mixing interference signal (30) of an optical wave within a first laser cavity of the first laser (110). The first self-mixing interference signal (30) is caused by first reflected laser light reentering the first laser cavity, the first reflected laser light being reflected by a particle receiving at least a part of the first laser light.
