LASER ARRAY APPARATUS AND PROJECTOR ILLUMINATION OPTICAL PATH THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/045732
Kind Code:
A1
Abstract:
Provided is a laser array apparatus, comprising: a laser array consisting of a plurality of sets of laser light sources (101, 102, ... 10N), each set of the plurality of sets of laser light sources (101, 102, ... 10N) comprising: a laser unit used for emitting a laser light source and a collimating lens corresponding to same, capable of radiating monochrome light beams and collimating; one or a plurality of reflector sets, each reflector set consisting of a first reflector (A01, B01, etc.) and a second reflector (A02, B02, etc.) matching the first reflector (A01, B01, etc.), the first reflector (A01, B01, etc.) and second reflector (A02, B02, etc.) being arranged in parallel; the plurality of sets of laser light sources (101, 102, ... 10N) are arranged parallel to each other, such that the light beams emitted by the plurality of sets of laser light sources (101, 102, ... 10N) are emitted in parallel in the same direction; the reflectors are configured to be used for changing twice the light-beam direction of the plurality of beams emitted by the laser light sources (101, 102, ... 10N); the plurality of laser light beams parallel in a plurality of directions is centralized and emitted in the same direction, and the slow-axis space of the laser array laser-light beams is compressed. The laser array apparatus employs reflectors in place of a set of telescope lenses in the prior art to compress the slow-axis distance of the laser array, thus compressing the spatial size of a plurality of laser light beams.
