Laser sensor for multi parameter detection

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, fo...

More Information
Summary: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.
