The projector with the scheme has the advantages of large system volume and high projector price, and the projection quality is good.
2. The laser scanning mirror vibrating method comprises the following steps: the laser galvanometer scanning system comprises a light source system, a galvanometer scanning system and a control system. The light source system mainly comprises a laser, a reflector and a prism, and laser emitted by the red, green and blue lasers is mixed into a polychromatic light beam through the reflector and the prism and enters the galvanometer scanning system. The light beam is incident on the reflecting mirror in the horizontal direction of the galvanometer scanning system, reflected and then incident on the reflecting mirror in the vertical direction, and then emergent and projected to a working plane to form a two-dimensional color scanning point array. The main function of the control system is to control the deflection of the mirror of the galvanometer scanning system to realize the movement of the laser beam in a preset scanning range, thereby realizing the effect of drawing color patterns on a screen.
The method uses a plurality of optical elements, has a complex and large system and high cost, is only suitable for displaying simple line-shaped images, has low resolution and limited expressive ability, and cannot display high-definition color images with rich details.
