Embodiment Construction
[0030] The following will be combined with Figure 1 to Figure 6 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on th...

The invention relates to the technical field of photoelectric detection equipment, in particular to a laser beam combining, shaping and homogenizing scanning device. The laser beam combining, shapingand homogenizing scanning device comprises a main laser, a beam shaping and homogenizing frame and a base, the beam shaping and homogenizing frame is composed of a shaping and homogenizing box, a connecting box, a light inlet cover and a moving plate, and the bottom of the connecting box is connected to the outer wall of the top of the shaping and homogenizing box through bolts; a connecting rod is welded to one side of the inner wall of the connecting box, the two sides of the exterior of the connecting rod are sleeved with sleeves correspondingly, the inner walls of the two sides, close to the connecting rod, of the connecting box are connected with electric telescopic rods through bolts correspondingly, the output ends of the electric telescopic rods are connected to one sides of the sleeves through keys and key grooves, and one sides of the sleeves are movably connected with movable rods through movable joints. A screw rod rotates and ascends in a limiting pipe, thus an adjusting bottom plate can be pushed upwards, the emitting width of light emitted out of a light passing pipe is adjusted, a laser light source is shaped into a certain width, then the light is emitted on a homogenizing lens piece, and the homogenizing lens piece homogenizes the light into a flat-topped light beam.
Description
technical field [0001] The invention relates to the technical field of photoelectric detection equipment, in particular to a laser beam combining, shaping, homogenizing and scanning device. Background technique [0002] With the development of sensing technology, control technology, manufacturing technology and other related technologies and the needs of people in production and life, three-dimensional measurement technology has gradually become a key research field in geometric quantity measurement technology. Three-dimensional measurement is the comprehensive measurement of the measured object. , to determine the three-dimensional coordinate measurement data of the measured object. [0003] Chinese patent number CN201720373148.9 provides a laser scanning device for three-dimensional scene measurement, including a light source, a laser phase modulator, a grating, a mirror, a lens, a distance measuring light receiving part, and an imaging light receiving part. The laser phas...
