Project module, mobile device and use of a project module

摘要

Projector module, complete with a radiation output with:(a) a laser source (10) trained to emit coherent electromagnetic radiation with a divergent beam profile;(b) a collective optics (20) designed to collide or converge the divergent radiation emitted by the laser source (10); and(c) a diffractive optical element, (30) designed to produce a projection pattern from which the group optics (20) collide or converge; where:(d) a deflector (40) designed to convert the divergent radiation emitted by the laser source (10) from a first direction into a second direction deviating from the first direction, before which the collection optics (20) are arranged or trained as a collection optics (20); and(e) the spot size of the divergent radiation on the diverter device (40) is less than 50% of the beam diameter immediately before the collection optics (20).
