Description

Multi-mode switching laser ranging module Technical Field The utility model relates to the technical field of laser ranging modules, in particular to a multimode switching laser ranging module. Background The laser ranging module is an electronic device part for measuring a distance by using a laser technique, and measures the time that the laser beam passes from being emitted to the target object to be reflected back, and then calculates the distance to the target object according to the speed of light. The above and the prior art have the defects that the laser ranging module is inconvenient to switch the shape of the emitted light beam, and the accuracy is affected in some special measurement scenes, for example, when a small target or a target with a shielding object in a complex environment needs to be measured, the laser light spot is too large, besides the reflected light of the target element, the reflected light of surrounding elements or a chip substrate is also received, and the additional reflected light signals interfere with measurement, so that the distance between the target elements cannot be accurately acquired. Therefore, a multimode switching laser ranging module is proposed.
