Abstract

The invention provides a semiconductor laser with an alignment adjustment device. The laser has a sleeve, tip set, a focal length adjustment screw, a convex lens, a spring and a semiconductor laser tube. The laser is installed in a round hole shape carrier. A head portion is taken as a turning point, a tail portion can carry out two-dimensional moving adjusting, a light emitting angle is changed and light beams align. The length of the tail portion of the sleeve is increased and adjusting precision is improved. The thickness of the tail portion of the sleeve is increased so that an adjusting mechanism can be installed. The adjustment mechanism is three-point set that is symmetrically distributed at the tail portion. The tail portion of the sleeve is in a trumpet-shaped opening state so that a screwdriver can be inserted to adjust each set. The two-dimensional adjustment of light spots emitted by a single semiconductor laser in a small-sized space at a far end position can be realized so as to achieve alignment. The function can be used in applications where densely-arranged laser emitters are required and light beams need to be aligned, such as the equipment of using a linear arraylaser beam to scan an object to realize dimensional measurement and imaging.

Description

technical field [0001] The invention relates to a semiconductor laser, in particular to a semiconductor laser with an alignment adjustment device. Background technique [0002] The line array laser can measure the one-dimensional projected image and size of the object at a vertical position, move the line array vertically to scan, and measure the two-dimensional projected image and size data of the front of the object; figure 1 . [0003] To improve measurement accuracy, it is necessary to reduce the laser cross-sectional size. The reduced cross-sectional dimensions make it difficult to produce and install laser beam alignment devices. [0004] At present, due to the rapid development of semiconductor lasers, the production process is becoming more and more perfect, and the market price is also very low, some as low as 0.7 yuan, which provides a basis for its large-scale application in the field of measurement. Especially in the measurement of human body size, it has many...
