METROLOGICAL ANALYSIS OF THE DIFFUSE LIGHT SOURCE OF VARIABLE BRIGHTNESS BASED ON CONJUGATE INTEGRATING SPHERES.

The paper highlights theoretical analysis of accuracy of the diffuse light source of variable brightness based on conjugate integrating spheres. We develop the calculation procedure of its accuracy when the design parameters are modified. In addition, we give some recommendations on designing the diffusive light source to provide necessary stability of brightness in the output aperture. [ABSTRACT FROM AUTHOR]
