Abstract

The invention discloses a refraction type laser scanning device. The refraction type laser scanning device comprises a semiconductor laser emitting source and a rotatable prism assembling unit. The rear end of the prism assembling unit is connected with a rotation driving device, and the rotation driving device and the semiconductor laser emitting source are located on the same side of the front side face and the rear side face of the prism assembling unit respectively or located on the two sides respectively. The prism assembling unit comprises at least two prism units which are equant. Each prism unit is an independent light-transmitting prism element. The direction of lasers emitted by the semiconductor laser emitting source and the axial direction of the rotation driving device are the same or an included angle is formed between the directions. The vertex angles of the adjacent prism elements are different. The refraction type laser scanning device is simple in structure, the light source and the driving device can be placed on the same side, the overall size is small, the occupied space is small, the production process is simple, control is easy, production cost is low, positioning is simple, reliability is high, and operation is convenient.

Description

technical field [0001] The invention relates to a laser scanning device, in particular to a refraction laser scanning device which is mainly used in laser medical treatment and laser beauty treatment. Background technique [0002] At present, with the rapid development of laser technology, lasers of various wavelengths emerge in an endless stream, and more light sources are used in the human health and beauty industries. Using the thermal characteristics of light and the selective absorption characteristics of human tissues for light wavelengths, targeted Change the internal tissue structure and performance of the human body to achieve the purpose of beauty, physical therapy and health. [0003] To act light on human tissue, the technology widely used at present is to scan with a reflective laser galvanometer. The principle is to install the reflector on the shaft of the swing motor, place two sets of motors perpendicular to each other, and the two sets of electrodes are not...
