Optics II: Systems

Abstract

When, as is often the case, a primary light source does not have either the required uniform radiance or sufficient area, and/or it cannot be positioned properly, the illumination stream must be modified. The most common transformations include changing the intensity of the source (concentrating it by the use of lenses and/or reflectors), modifying the size and angular distribution of the light, diffusing the source, varying its spectral characteristics, and shifting the light source’s apparent location. In this chapter, we explore how optical components can be used to modify the characteristics of the illumination source, providing more flexibility to the MV designer.
