The method for measuring the color of the paint film of the optical camouflage paint generally adopts the method specified in GB/T3979, a spectrophotometric method and a colorimetry method.
The existing measuring method has the defects that the width of a diffusion overlapping area of an optical camouflage paint film is judged by a visual method, and the artificial difference and the quantitative measurement cannot be realized. The methods specified in GB/T3979, spectrophotometry and colorimetry, are capable of measuring the color of an object and cannot determine the width of the region of spreading overlap of an optically camouflage paint film.

Detailed Description
The technical scheme of the invention is further described in detail in the following with the accompanying drawings of the specification.
The invention relates to a method for measuring the width of a paint film diffusion overlapping area of an optical camouflage paint, which comprises the following steps:
the boundary area of the A, B two color patches across the optically camouflage paint film was scanned vertically at a uniform speed from the light source emitted by a standard white light source. When the emitted white light is in two color block areas of an A color block and a B color block, the wavelength of the reflected light corresponds to the wavelength of the two color block colors respectively, when the emitted white light is scanned in two optical camouflage coating paint film diffusion overlapping areas of the A color block and the B color block, the wavelength of the reflected light is changed by the wavelength different from the wavelength of the two color block colors of the A color block and the B color block, the time t when the wavelength of the incident light scanning A, B changes to form an inflection point and the moving speed v are measured, and the scanning length L is t multiplied by v, so that the width of the optical camouflage coating paint film diffusion overlapping area can be calculated. The length L is in microns, the time t is in seconds, and the emitted white light scanning velocity v is in microns/second.
As shown in FIGS. 1 and 2, the optical camouflage paint film spread overlap area width is calculated as follows:
△L＝L2-L1
in the formula: Δ L: the width of the paint film diffusion overlapping area;
l1: the length of the distance from the starting point when the light source leaves the color of the color block A and the inflection point appears is micrometer;
l2: the length of the distance from the starting point when the color of the light source enters the color block B and the inflection point appears is in a unit of micrometer;
the working principle of the invention is that white light is emitted through an illuminating body (such as a standard white light source) capable of generating white light, the emitted light forms a light spot with an effective measuring diameter through a focusing system (such as an optical component), the white light irradiates on an optical camouflage paint film (2 color butt joint areas) at a certain incidence angle, a reflected light receiving measuring device (such as a spectrophotometer and an electric integrator) is placed at the position of a reflection angle, the standard white light source moves perpendicular to the optical camouflage paint film diffusion overlapping area at a fixed speed, and the width of the optical camouflage paint film diffusion overlapping area is calculated according to the measured wavelength, intensity change and moving speed coupling of the reflected light.
