Method for measuring width of diffusion overlapping area of optical camouflage paint film

Abstract

The invention relates to a method for measuring the width of a diffusion overlapping region of an optical camouflage paint film, the measuring method is characterized by comprising the following specific steps: emitting white light by a standard white light source, vertically scanning a junction region of a color block A and a color block B of the optical camouflage paint film by the emitted white light at a uniform speed, and when the emitted white light sequentially scans the color block A and the color block B, measuring the time t1 and the time t2 when the wavelength of the reflected light has two inflection points, calculating L1 and L2 according to the formula that the scanning length L is equal to t * v, v is the moving speed of the emitted white light, and the width deltaL of the diffusion overlapping area of the optical camouflage paint film is calculated according to the formula that deltaL is equal to L2-L1. The optical characteristics of adjacent optical camouflage paint film color blocks are continuously measured, and the technical problems that the visual method and the method specified by GB/T3979 have differences and quantitative measurement cannot be achieved are solved.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a method for measuring the width of an optical camouflage paint film diffusion overlapping area. Background technique [0002] The existing optical camouflage paint film diffusion overlapping area measurement method adopts the visual method, which can only judge the optical camouflage paint film diffusion overlapping area width from the senses, and different people have significant differences in observation. The measurement method of optical camouflage paint film color generally adopts the method specified in GB / T3979, spectrophotometric colorimetry and colorimeter method. [0003] The defect of the existing measurement method is that the width of the overlapping area of ​​the optical camouflage paint film is judged visually, which has artificial differences and defects that cannot be quantitatively measured. The method specified in GB / T3979, spectrophotometric ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for measuring the width of the overlapping area of ​​the optical camouflage paint film diffusion, which realizes the continuous measurement of the optical characteristics of the adjacent optical camouflage paint film color blocks, and overcomes the existence of the visual method and the method specified in GB / T3979 Variability and technical issues that cannot be quantified
