Abstract

The invention provides a laser scanning method, a device and imaging equipment. The laser scanning method comprises steps that: adjusting coefficients are calculated according to optics parameters and a compensation principle of a laser scanning device; laser pulses emitted by a light source are adjusted according to the adjusting coefficients; the laser pulses emitted by the light source are adjusted to be parallel light; the parallel light is turned to be scanning light through a light beam deflector which uniformly rotates; the scanning light is focused on a scanned object. According to the method, the light source is adjusted through the adjusting coefficients, so light spots gathered on the object to be scanned have uniform consistency, and thereby accurate scanning for the scanned object can be realized.

Description

technical field [0001] The present invention relates to laser scanning technology, in particular to a laser scanning method, device and imaging equipment. Background technique [0002] Laser scanning technology is indispensable in the fields of printing imaging, graphic copying, laser coding and medical imaging. [0003] The specification of Chinese patent application No. 200610013649.2 discloses a common laser scanning device, figure 1 It is a structural schematic diagram of a laser scanning device in the prior art. Such as figure 1 As shown, the laser scanning device includes: a lens 1 , a lens 2 , a beam deflector 3 , a collimator lens 4 , and a light source 5 . Wherein, the light source 5 emits laser light with the same pulse duration and the same power. Lens 1 and Lens 2 constitute a scanning lens F-θ mirror. The beam deflector 3 is a hexaprism with 6 reflective surfaces. The beam deflector 3 rotates at a constant speed, so as to reflect the laser light emitted by...
