Abstract
Description
technical field
[0001] The invention relates to a measurement method, in particular to a method for improving the measurement accuracy of a photometric measuring instrument. Background technique
[0002] In light radiation measurement, there are two types of energy-related quantities: one is physical, referred to as radiation; the other is physiological, called photometric (including luminous flux, luminous intensity, illuminance, luminance, etc.). The radiation amount of light includes all radiant energy of ultraviolet radiation, visible light and infrared radiation. Human vision not only excludes invisible ultraviolet radiation and infrared radiation, but also in terms of quantity, the light radiation energy felt by the human eye is not completely equal to the actual energy of the visible part of light radiation (visible light). The basic method of photometric measurement can be divided into two types according to the different receivers used to measure the photometric qu...
