Problems solved by technology
This method is time-consuming and labor-intensive in the adjustment process, and the adjustment accuracy is not easy to control. At the same time, due to the different conditions of the photoelectric measurement systems of different platforms, the same deflection light tube cannot be used universally. These problems make the optical path deflection room to be improved.

The invention discloses a position-adjustable light path turning method and device. The light path turning method is realized by the light path turning device composed of an upper light cylinder structure, a multi-tooth indexing table, a screw rod and a lower light cylinder structure. The lead screw is installed under the multi-tooth indexing table, the upper light cylinder structure is installedon the multi-tooth indexing table, the lower light cylinder structure is installed on external threads of the lead screw, right-angle pentaprisms are installed in the upper and low light cylinder structures and used for turning a light path, light through holes used for light path transmission are formed in the middle of the multi-tooth indexing table and the middle of the lead screw, and the light through holes are coaxial during installation. The optical path turning method has the advantages that the position of the optical path is adjusted through the multi-tooth indexing table and the lead screw to turn the light path of the photoelectric measurement system, the adjustment precision is improved, the adjustment process is simplified, operation is convenient and easy to achieve, and themethod is suitable for different platforms. The light path turning device improves the angle precision of light path turning, and enhances the adaptability and reliability of the system.
Description
technical field [0001] The invention relates to a photoelectric measurement system, in particular to a position-adjustable optical path refraction method and an optical path refraction device thereof. Background technique [0002] In vehicle-mounted and ship-borne photoelectric measurement systems, there are often situations where the height and angle of the installation platform of photoelectric measurement equipment are different from those of the measured object, making it impossible for the photoelectric measurement system to perform photoelectric measurement directly. The traditional method uses a deflection light pipe to adjust the relative height and relative angle between the photoelectric measurement equipment platform and the measured object, so as to realize the light path refraction, so that the light reference of the photoelectric measurement equipment can be transmitted to the measured surface on the measured object, thereby Complete photoelectric measurements....
