Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0039] figure 1 It is a scanning system in the prior art. The scanning system includes a reflective rotating mirror 11 and a laser 12, which are used to scan the image A from the horizontal direction. When the reflective rotating mirror 11 is in the initial position, the light emitted by the laser 12 to itself is reflected to the leftmost of the first row of the image A. at the pixel. When the reflective rotating mirror 11 rotates once, it will reflect the light emitted by the laser 12 to t...

Abstract

The invention discloses a laser scanning system, apparatus and method. The system is used for scanning a scanning area comprising x independent areas from the first to xth independent areas. The system comprises: a light-reflecting rotation mirror and x lasers from the first to xth lasers; wherein the x lasers are used for transmitting light to the light-reflecting rotation mirror at a certain angle; the light-reflecting rotation mirror is used for transmitting light transmitted by the yth laser to the yth independent area during rotation; and the x>=2 and x>=y>=2. The plurality of lasers are arranged to carry out scanning at the same time, so that the area to be scanned by the lasers is reduced and distinguishability of the laser scanning system is improved.

Description

technical field [0001] The invention relates to the field of scanning, in particular to a laser scanning system, device and method. Background technique [0002] With the development of optical technology and projection display technology, laser scanning system has become more and more popular among enterprises and even families. The ability to provide high-resolution images has become an important factor for testing laser scanning systems. [0003] The current method of improving the resolution of the laser scanning system cannot greatly improve the resolution due to the influence of factors such as the rotation frequency of the reflective rotating mirror and the moving frequency of the scanned object. Therefore, at present, there is an urgent need for a technology to solve the above problems. Contents of the invention [0004] The present invention aims to provide a laser scanning system, device and method to improve the scanning resolution of the laser scanning system...
