AI Technical Summary

Technical Problem

Existing spectral imaging colorimeters cannot perform spectral analysis, and their traditional structures are not adaptable to space constraints, requiring additional space.

Method used

A periscope-type spectrocolorimeter is used, integrating the spectrometer and periscope on the color wheel. The color wheel is driven to rotate by a stepper motor, and the light signal is transmitted to the spectrometer for analysis using the 45Β° optical path of the periscope. Combined with a Hall sensor, precise position detection and rotation control are achieved, generating a multispectral data cube or color analysis report.

Benefits of technology

It achieves high-precision spectral analysis within a limited space, with more accurate data calibration, is easy to use, generates multispectral data cubes or color analysis reports, and obtains the spectral characteristics of the target such as reflectance and radiance.

Abstract

The utility model discloses a periscope formula spectrum colorimeter, including shell, color wheel disc, intelligent camera and camera lens, and color wheel disc rotation is connected in the front side of shell, and intelligent camera is coaxial with camera lens and is arranged, and intelligent camera is in the back side of shell, and periscope one end is equipped with the light entrance mirror, and the other end is equipped with the light exit mirror, periscope is integrated on color wheel disc, and effective utilization space has solved the shortcoming that traditional imaging colorimeter has no spectrum diagram. The imaging colorimeter of integrated spectrometer can carry out data calibration to the measured sample at the test site, so that the data measured by the imaging colorimeter is more accurate, and convenient to use. The spectrum diagram is obtained through the operation analysis in the spectrometer, the spectrum data and the image are fused, the multispectral data cube or color analysis report is generated, and the spectral characteristics (such as reflectivity, radiation intensity) of the target are obtained.
