本発明は分光感度がそれぞれ異にる光電変換素子に対し
て、分光分布の異なる光源の放射を測光量をもとに定量
化する測光装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photometric device that quantifies radiation from light sources with different spectral distributions for photoelectric conversion elements having different spectral sensitivities based on photometric amounts.
主に可視光に分光分布をもつ光源の放射は通常測光量と
して取扱われ、分光感度が標準比視感度に合致した受光
器により測定される。これにより光源の分光分布のいか
んを問わず、光源間の放射比較が容易にできる。The radiation of a light source with a spectral distribution mainly in visible light is usually treated as a photometric quantity, and is measured by a photoreceiver whose spectral sensitivity matches the standard luminous efficiency. This makes it easy to compare radiation between light sources, regardless of the spectral distribution of the light sources.

ならず、その都度繁雑な作業を伴なう欠点を有する。On the other hand, the photoelectric output of a general photoelectric conversion element that does not meet the standard luminous efficiency is usually expressed as a photocurrent per unit irradiance. Generally, to measure irradiance, there are known types of receivers that measure temperature rise due to radiation, such as thermopiles and bolometers, but they have drawbacks such as the difference between the radiation from the object to be measured and the background radiation, which requires time for calibration. Therefore, the photoelectric output of the photoelectric conversion element is practically expressed as a photocurrent (mu/Ix) corresponding to unit illuminance. In this case, since the spectral sensitivities of the illuminance meter and the photoelectric conversion element differ, the photoelectric output of the photoelectric conversion element takes different values even if the illuminance value is the same for light sources with different spectral distributions. Conversely, the photoelectric output of a photoelectric conversion element may take the same value even if the illuminance is different. That is, each photoelectric output varies depending on the type of photoelectric conversion element and the type of light source. Therefore, in order to obtain these values, it is necessary to prepare and actually measure each photoelectric conversion element and light source, which has the disadvantage of requiring complicated work each time.

いても同様の扱いができる。The present invention relates to a new photoelectric characteristic measuring device which eliminates the above-mentioned drawbacks of the conventional method, and the details thereof will be explained below.In general, photoelectric conversion elements can be classified into charge storage type and non-storage type. The former is represented by solid-state image sensors and various photosensitive materials, and the latter is represented by silicon photovoltaic cells. Of the photoelectric conversion elements described above, a charge storage type will be described below as an example, but non-storage types can also be treated in the same way.

ここに、Po(λ)は基準光源の相対分光分布。Saturation exposure (1X-8) is generally used to express the sensitivity of a charge storage type photoelectric conversion element. It is assumed that the saturation exposure amount, that is, the photoelectric output, of the test photoelectric conversion element is equal both when IIX under the standard light source and when 1/KeIX under the test light source. At this time, the output of the illumination meter is 11. ]E2 is

換素子の場合などに適用できる。This Ke will be referred to as an exposure amount conversion coefficient. however,
All four integral values in equation (3) are not zero;
In other words, the condition is that the spectral distribution of the test light source and the spectral sensitivity of the test light receiver are partly in the acceptable wavelength range. It can be applied to light sources and photoelectric conversion elements.

ることができる。Based on the above considerations, the value obtained by multiplying the illuminance value on the surface of the photoelectric conversion element by Ke for the test light source corresponds to the illuminance value when the photoelectric conversion element is irradiated with light from the standard illuminant. Based on this theory, if you calculate the spectral sensitivity of a certain photoelectric conversion element, you can calculate it without having to take the trouble of measuring the photoelectric output of the photoelectric conversion element for light sources with different spectral distributions. , the photoelectric output can be determined by determining the illuminance on the surface of the photoelectric conversion element and the exposure amount conversion coefficient.

簡単にその光電出力を測定し定量化できる。(1) Conventionally, the saturation exposure amount for a certain test photoelectric conversion element differed depending on the type of light source. Therefore, the photoelectric output could not be clarified unless both the saturation exposure amount and the name of the light source were listed. With this device, Ke can already be measured, so by simply multiplying the illuminance measurement value by the above Ke, the photoelectric conversion element can be irradiated with light from the reference light source (standard light source) to correspond to the next illuminance value. And & m ff, +
, the relationship between i and photoelectric output is determined systematically.As a result, for light sources whose spectral radiation intensity is difficult to measure, such as light sources built into equipment, it is necessary to calculate the exposure amount conversion coefficient using the above device once. As long as the photoelectric output is easily measured and quantified by separately measuring the illuminance value.

It also has the advantage of making it easy to compare the photoelectric output when various colored glass filters are inserted into the light source, making it extremely effective for evaluating light sources for information devices and optical systems for information reading devices. do.
