Abstract
A system and method for generating reflective dark field illumination in an imaging system that includes a set of elementary illuminators, each of the set of elementary illuminators including a light source, a lens assembly and an illuminator aperture; and a bright field/dark field (BD) lens. The set of elementary illuminators are positioned in a ring-like shape to direct light towards a port of the BD lens. Depending on an application of the imaging system, a lens assembly focal distance and a distance between a light source and a lens assembly are determined based on the application.
