In-cabin optical environment compatibility evaluation method for military goggles

Abstract

The invention discloses an in-cabin optical environment compatibility evaluation method for military goggles. The method comprises the following steps: 1) measuring the original spectrum distribution condition of each color in an in-cabin optical environment to be assessed through a spectrum analyzer; 2) measuring a transmittance curve of the goggles to be evaluated through a spectrophotometer; 3) calculating to obtain the spectral distribution condition of each color in the optical environment in the cabin after the color penetrates through the goggles; 4) calculating the original chromatic value of each color in the optical environment in the cabin and the chromatic value of each color after penetrating through the goggles according to the original spectral distribution and the spectral distribution after penetrating through the goggles; and 5) comparing the original chromatic value of each color with the chromatic value of each color after penetrating through the goggles, and calculating to obtain the chromatic aberration value of each color. By using the method, the optical compatibility quantitative assessment of the goggles can be carried out only through the lens transmittance curve, a direction can be provided for improving the visual effect of the lens, meanwhile, the test cost is greatly reduced, and the development efficiency is improved.

Description

In-cabin optical environment compatibility evaluation method for military goggles technical field The present invention relates to aviation life-saving visual efficacy testing technology, relate in particular to a kind of in-cabin optical ring of military goggles Environmental compatibility evaluation method. Background technique Military goggles, as an important component of pilot helmets, play a role in protection against airflow blowing and strong laser power. The glare protection function needs to be perfectly compatible with the optical environment such as the display screen and indicator lights in the aircraft cockpit. When observing the optical environment in the cabin through the lens, there is no obvious chromatic aberration phenomenon, and it does not affect the pilot's understanding of the various aspects of the optical environment in the cabin. Color discrimination. The compatibility evaluation of the existing goggles and the optical environment in the ...

AI Technical Summary

Problems solved by technology

[0003] The evaluation of the compatibility between the existing goggles and the optical environment in the cabin is mainly subjectively measured by pilots wearing them in actual flight tests. Misunderstanding of visual effects due to inaccurate description or misunderstanding

In addition, in order to achieve the visual effect that finally meets the combat needs, a large number of in-cabin visual efficacy verification tests need to be carried out during the development of goggles, which increases the economic cost of goggles development
