Abstract

An electronic flash, imaging device and method for producing flashes of light uses a diffractive optical element to produce a flash of light having a rectangular radiation pattern. The diffractive optical element is configured to diffract light emitted from a light source such that the radiation pattern of the light emitted from the diffractive optical element is rectangular to produce the rectangular flash of light.
