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.

Claim (Index 1):
A laser sensor module comprising:\n at least one first laser; at least one first detector; at least one electrical driver; and at least one first optical device; wherein the first laser is arranged to emit a first laser light based on signals provided by the at least one electrical driver, wherein the first optical device is arranged to focus the first laser light on a focus region, wherein the laser sensor module is arranged to control a distance between the laser sensor module and the focus region such that there are at least a first mode and a second mode of the laser sensor module, wherein in the first mode the focus region is at a first distance and in the second mode the focus region is at a second distance, wherein the second distance is different than the first distance, wherein the at least one first detector is arranged to detect a first self-mixing interference signal of an optical wave within a first laser cavity of the first laser, wherein the first self-mixing interference signal is caused by a first reflected laser light reentering the first laser cavity, wherein the first reflected laser light is received in the first mode, wherein the first self-mixing interference signal is used to determine a first physical parameter, wherein the first physical parameter is related to a movement of an object, wherein the laser sensor module is arranged to detect a second self-mixing interference signal, wherein the second self-mixing interference signal is caused by a second reflected laser light, wherein the second self-mixing interference signal is determined in the second mode, wherein the second self-mixing interference signal is used to determine a second physical parameter being related to a detection of a particle density or a particle size, wherein the second physical parameter is different than the first physical parameter.
