Light source spectrum modulating device

Abstract

The invention provides a light source spectrum modulating device. The light source spectrum modulating device comprises a light source, a first collecting optical unit, a chromatic dispersion unit, a digital micromirror array, a second collecting optical unit and a light uniformly blending unit, wherein the first collecting optical unit is used for collecting the light irradiation of the light source; the chromatic dispersion unit is used for chromatically dispersing the light irradiation collected by the first collecting optical unit, and imaging; a digital micromirror array is formed on a focal surface of the chromatic dispersion unit and is used for controlling the overturning state of each micromirror in order to select different spectrum positions and spectrum bandwidths; the second collecting optical unit is used for collecting the light irradiation reflected by the digital micromirror array again and transferring the collected light irradiation into the light uniformly blending unit; and the light uniformly blending unit is used for blending and recombining the separated single-light irradiation. By adopting the light source spectrum modulating device, the light source spectrum can be distributed again, and the distribution characteristic of the light source spectrum can be changed; the light source spectrum modulating device can be applied to the field of calibrating of optical instruments and simulation test; and by adopting the technology provided by the invention, the calibrating precision of the optical instruments and the simulation test capacity can be improved.

AI Technical Summary

Benefits of technology

This technology improves how we produce lights that have specific colors or patterns on their surface by adjusting its color temperature (CCT) based on factors like ambient brightness levels at different times during use. It also allows us to create unique spectra from these colored lights which are used for various purposes such as optics-based measurements and simulations.

Problems solved by technology

This patented technical problem addressed by this patents relates to accurately measuring various important factors like spectra distributions, space distribution, etc., during optics calibration/simulation testing without requiring separate measurements from each other. Current methods require complete control over both spectral properties (spectrum) and spatial dimensions but these techniques have limitations due to their dependence upon specific types of light sources used together.
