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 14):
A method of detecting at least two physical parameters, the method comprising the steps of:\n emitting a first laser light from a first laser; focusing the first laser light on a focus region; controlling a distance between the laser sensor module and the focus region such that there are at least a first mode and a second mode, 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; receiving a first reflected laser light in a first laser cavity of the first laser; determining a first self-mixing interference signal of an optical wave within the first laser cavity of the first laser, wherein the first self-mixing interference signal is caused by the first reflected first laser light reentering the first laser cavity, wherein the first reflected laser light is received in the first laser cavity in the first mode; determining the first physical parameter using the first self-mixing interference signal, wherein the first physical parameter is related to a movement of an object; determining a second self-mixing interference signal in the second mode, wherein the second self-mixing interference signal is caused by second reflected laser light; and using the second self-mixing interference signal to determine a second physical parameter, wherein the second physical parameter is different than the first physical parameter, wherein the second physical parameter is related to a detection of a particle density or a particle size.
