Abstract

The invention provides a detection calibration device and method of transmittance ratio and reflectance ratio measuring instrument. The method comprises the following steps of S1, moving a cover covering a super black light absorption film at inside to perform measurement so as to obtain first measurement data; S2, moving a cover covering a total reflection mirror surface film at inside to performmeasurement to obtain second measurement data; S3, moving a cover covering a directional reflection crystal film at inside for measurement so as to obtain third measurement data; S4, calculating a ratio with the target value; then, regulating the proportion parameters of a transmission signal digital gain amplification circuit and a reflection signal digital gain amplification circuit of the measurement instrument according to the measurement data; S5, moving a plurality of pieces of glass with the fixed calibration values one piece by one piece to the right front side of the measurement instrument to perform measurement so as to obtain fourth measurement of the measuring instrument; sequentially performing comparison on the calibration value and the fourth measurement data to generate ratio data; configuring the ratio data into the measurement instrument according to the proportion parameters; fitting the data into a standard curve; S6, inspecting the calibration accuracy; completingthe calibration.

Description

technical field [0001] The invention relates to the technical field of projection-reflectance measurement, in particular to a detection and calibration device and method for a transmittance-reflectance measuring instrument. Background technique [0002] At present, there is still a lack of a fast and efficient device and method for zero-value calibration and precision calibration of transmittance and reflectance measuring instruments, which seriously affects the factory quality and user experience of products. [0003] In the existing method, N (N needs to be greater than 20) calibrated glasses with different transmittance and reflectance ratios are prepared first. The determination steps are as follows: [0004] Measure the calibrated glass with the transmittance and reflectance measuring instrument to be tested, and record the measurement results; [0005] Adjust the ratio parameter of the analog scaling circuit by comparing N actual measurement result values ​​with N ca...
