Description

Technical Field

[0001] The utility model relates to the technical field of imagers, in particular to an imager capable of preventing interference from external light. Background Art

[0002] The image measuring instrument is based on CCD digital images, relying on computer screen measurement technology and powerful software capabilities of spatial geometry calculations. After the computer is installed with special control and graphic measurement software, it can quickly read the displacement value of the optical ruler, and obtain the desired results instantly through software module calculations based on spatial geometry; and generate graphics on the screen for the operator to compare images with shadows.

[0003] Most existing imagers do not have a dedicated light-shielding device, which limits their use to a certain extent. For example, the utility model with patent number CN219301523U does not take light-shielding into consideration in its design. During use, since there is no light-shielding device, when the external light is strong or the light changes frequently, the device will be disturbed by the light from the outside. This interference may affect the normal operation of the imager and may even cause deviations in the measurement results. Utility Model Content

[0004] The purpose of the utility model is to provide an imager that can prevent interference from external light, so as to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the diagonal brace is X-shaped to enhance the stability between the slide rails.

[0007] Preferably, a plurality of sliding blocks are arranged in a rectangular shape on the side of the light shielding ring to reduce the sliding resistance between the light shielding ring and the slide rail.

[0008] Preferably, an imager workbench is provided on the mounting plate, and an optical moving component is provided on the imager workbench to expand the recognition range of the imager.

[0009] Preferably, one side of the back plate and one side of the slide rail are both provided with legs to lift the slide rail off the ground and prevent foreign objects from getting stuck in the light shielding ring and making it unable to move.

[0010] Preferably, the limit rod is inclined at a certain angle between the slide rails and abuts against one side of the imaging instrument workbench to prevent the back plate from abutting against the optical moving component.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model achieves the purpose of shielding external light through the back plate and the light shielding ring, and provides a dark light environment for the imager through the specially designed light shielding ring and back plate. The design of this environment takes into account the sensitivity of the imager to light, thereby effectively reducing the impact of external light on its operation. By reducing the light intensity in the environment, the imager can capture images under more ideal conditions, which not only improves the clarity of the image, but also enhances the color restoration. Therefore, in daily applications, this dark light environment can significantly improve the overall performance and reliability of the imager. BRIEF DESCRIPTION OF THE DRAWINGS
