Light and color multiplexing continuous regulation device

Abstract

The invention relates to a light and color multiplexing continuous regulation device, and belongs to the technical field of optical precision measurement. The light and color multiplexing continuous regulation device specifically comprises a front flange plate, three light barriers, six color filters, a support mechanism A, a support mechanism B, a triangular support and a rear flange plate, wherein the front flange plate, the support mechanism A, the support mechanism B and the rear flange plate are close to each other in parallel, circular center holes are respectively formed on the front flange plate, the support mechanism A, the support mechanism B and the rear flange plate, the centers of circles of the four center holes are coaxial and the four center holes are equivalent in caliber; the triangular support is positioned in the center holes of the support mechanism A and the support mechanism B; three identical radial grooves are formed on each of two end surfaces of the support mechanism A and used for mounting of the color filters which can be moved out; and the grooves which are the same with those on the support mechanism A are formed on the support mechanism B and used for mounting of the light barriers which can be moved out. According to the light and color multiplexing continuous regulation device provided by the invention, incident light can be divided into threebeams of light in different colors, and the respective light flux of each of the three beams of the light can be changed or only the light flux of the incident light is changed, so that continuous color mixing in a large color domain range and the continuous color mixing in a large dynamic range can be further realized.

Description

technical field [0001] The invention relates to a multiplexing device for continuous color adjustment with a large color gamut and continuous light adjustment with a large dynamic range, and belongs to the technical field of optical precision measurement. technical background [0002] More than 95% of the external information that people feel comes from vision, so the quality of visual characteristics is directly related to human production, life and work. Therefore, the measurement of color resolution, illuminance threshold, and contrast threshold becomes more and more important. At present, the instruments and equipment on the market are cumbersome in structure and single in function, which are difficult to meet the needs of measurement. [0003] In order to realize the measurement of resolution, illuminance threshold and contrast threshold in a system at the same time, it is necessary to have a continuous color adjustment device in a large color gamut and a multiplexing ...

AI Technical Summary

Problems solved by technology

If the saturation of the filter is increased, the energy loss of the light source will increase, and it is difficult to meet the energy requirements of the test

[0006] At present, the method of adjusting luminous flux is mainly through attenuation film, polarizer, etc., but these devices are difficult to achieve multiplexing with color adjustment
