Embodiment Construction

[0058] Such as figure 1 as shown, figure 1 A schematic diagram of the vibration image of the galvanometer. It should be noted that the vibrating image referred to in this application is the image generated by using the three light sources of red, green and blue to emit parallel light beams to mix and enter the vibrating mirror and output to the photosensitive chip from the vibrating mirror. Commonly used test images, which will not be described in detail.

[0059] The vibrating image contains multiple basic vibrating images 01 , and the content of the entire vibrating image is the repetition of the multiple basic vibrating images 01 . The basic vibration image 01 includes four groups of thick vibration lines and thin vibration lines, namely vibration line 1 011, vibration line 2 012, vibration line 3 013 and vibration line 4 014.

[0060] Among them, 1011 kinds of vibrating lines include red vibrating thick line 11, red vibrating thin line 21, green vibrating thick line 12,...

Abstract

The invention discloses a galvanometer parameter adjusting method. The method comprises the following steps: acquiring vibration images corresponding to a galvanometer in a plurality of set differentparameter states, wherein the parameters comprise a gain parameter and a duration parameter; obtaining an offset value between the vibration thick line and the vibration thin line in each vibration image; and selecting the gain parameter and the duration parameter corresponding to the minimum offset value in the offset values as the parameters of the galvanometer, and adjusting the parameters of the galvanometer. According to the invention, the parameter size of the galvanometer is determined by utilizing the correlation between the offset values between the vibration thick line and the vibration thin line in the vibration image and whether the galvanometer parameters are proper or not, so that the working performance of the galvanometer is ensured. The invention further provides a galvanometer parameter adjusting device and equipment, and the galvanometer parameter adjusting device and equipment have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of vibrating mirrors, in particular to a parameter adjustment method, device, equipment and computer-readable storage medium for vibrating mirrors. Background technique [0002] The galvanometer is a component of the optical machine, located between the DMD (Digital Micromirror Device) and the lens. The main body is a glass lens and two coils, which can drive the lens to vibrate slightly up and down in the x / y direction. The main principle is that there is refraction when light passes through the lens, and the refraction angle is related to the angle of the lens. Using this principle, the left and right vibration of the lens is controlled by driving the coil to make a pixel point on the DMD reflect to four positions at four time points. The purpose of improving the resolution of the optical machine picture. [0003] In the actual working process of the galvanometer, a variety of different parameter...
