Metrological Characteristics of a Diffuse Emitter Based on the Integrating Sphere with Light-Emitting Diodes

The aim of this work is developing, with the help of the developed numerical method, analyzing the impact of the main elements of DV on its metrological characteristics and development on this basis, recommendations for designing next-generation high-precision IS. To identify the main parameters of a spherical surface that affect on formed brightness field.

The Numerical Method of Analysis of the Diffuse Emitter Intensity Based on the Integrating Sphere

This paper develops a novel numerical method for the analysis of the diffuse transmitter based on the integrating sphere, which allows evaluating the parameters of the field formed by the emitter brightness taking into account the effects of micro- and macrostructure and its sources of radiation. The method is based on the geometrical ray propagation laws in the space, their specular and diffuse reflection on surface of the sphere and its elements such as the hump, pit, fence, patch.

Metrological Analysis of the Diffuse Transmitter Based on the Integrating Sphere with Light-Emitting Diodes

This paper highlights the metrological analysis of the diffuse transmitter based on the integrating sphere with the cosine radiation sources. We propose novel simplified calibration methods of diffuse emitters.

Theory of the diffuse transmitter on the basis of an integrating sphere with light-emitting diodes

We develop a theory of the diffuse source with cosine radiation sources which allows describing the formation of the brightness field in the output aperture in a first approximation. We obtain the engineering formulas and also recommend how to calculate and to design a diffuse source with specified parameters.
