Paper Abstract

A novel form of reflector, incorporating an array of microlenses, is described. Incident illumination is reflected through an angle of deviation that is nominally independent of the angle of incidence. The reflector performs a function that is similar to a retroreflector, but differs in that the angle of deviation is other than 180 degree(s). This dispenses with the need to use a beamsplitter to extract the reflected wavefront. The consequent reduction in light loss is of benefit to high speed and other forms of photography.
