Problems solved by technology
Although the above method can achieve the purpose of optical path monitoring, the transmitted light and reflected light are transmitted in different directions after passing through the spectroscopic diaphragm, generally in opposite directions, and cannot be transmitted in the same direction, and the utilization rate of the light beam is low. Will cause the overall system to need a larger size to meet the optical transmission

Abstract
The present invention relates to the field of optical path monitoring, in particular to an optical path monitoring device and system for splitting light by a wedge angle plate. The optical path monitoring device includes a light source, an angle wedge plate, a collimating lens and a monitoring chip. The reflective surface, the light source emits light to the first reflective surface, and is divided into reflected light and transmitted light. After the reflected light passes through the collimating lens, it outputs the first collimated light to the monitoring chip. The monitoring chip monitors the power of the first collimated light, and the transmitted light After passing through the second reflective surface, it is reflected back to the first reflective surface, and then passes through the collimating lens to output the second collimated light. After being reflected twice by the angle wedge, the transmitted light is collimated by the collimator lens and becomes two beams of parallel light in the same direction, so that it is convenient to collect the light that needs to be monitored and the light used for output, and reduce the overall device size of.
Description
An optical path monitoring device and system for wedge angle beam splitting technical field [0001] The present invention relates to the field of optical path monitoring, in particular to a light path monitoring device and a system for splitting light by a wedge angle sheet. Background technique At present, in the free optical path, most of the spectroscopic diaphragms are used for light splitting, and the spectroscopic diaphragms have a certain transmittance and reflectance. The light beam is divided into transmitted light and reflected light after passing through the beam splitting diaphragm, among which, one beam of light is used for monitoring, and the other beam is used for relaying. Continuous transmission to achieve optical output. Although the above methods can achieve the purpose of optical path monitoring, the transmitted light and reflected light are After passing through the beam splitter, it is transmitted in different directions, generally in the opposite...
