Test method for radiance of night vision compatible lighting systems

Abstract

The invention belongs to the aviation lighting test technical field and provides a radiance test method of a night vision-compatible lighting system. According to the method, the discrete function of a standard light source under a condition that no optical filters are adopted is measured by using a spectroradiometer; the discrete function of the same standard light source under a condition that an optical filter is adopted on an incident light path, is measured; the ratio of the two discrete functions is calculated; the wavelengths of the standard light source are measured through a grating monochromator one by one; sampling and gating amplification are performed on signals outputted by an image intensifier; a spectral response discrete function is calculated according to the output signals; the ratio and the spectral response discrete function are multiplied, and curve fitting is performed according to the multiplication result; and integration is performed, the radiance value of the night vision-compatible lighting system is calculated.

Description

technical field [0001] The invention relates to the technical field of aviation lighting testing, in particular to a radiance testing method for a night vision compatible lighting system. Background technique [0002] Domestic night vision compatible lighting systems have been installed and used on several types of aircraft. As an important parameter index of night vision compatible lighting fixtures, night vision compatible radiance directly affects the adaptability of pilots to the night vision environment. Therefore, the standards related to aircraft night vision compatible lighting systems all propose specific parameters for night vision compatible radiance value requirements. However, the current domestic test methods cannot accurately measure the night vision compatible radiance value. [0003] The night vision compatible radiance value of aircraft night vision compatible lighting fixtures is directly related to the night vision helmet worn by the pilot of this type ...

However, the current domestic test methods cannot accurately measure the night vision compatible radiance value

[0003] The night vision compatible radiance value of aircraft night vision compatible lighting fixtures is directly related to the night vision helmet worn by the pilot of this type of aircraft, but the current domestic night vision compatible radiance test methods do not take this factor into account, so the measurement results are all There is a certain deviation
