Abstract
An apparatus and method for determining optical properties of an object includes a tunable monochromatic light source and an optical system for illuminating at least one point of the object with light from the light source, and collecting light reflected from the object. A biaxial birefringent crystal intercepts a beam of light reflected from the object and propagates the beam along an optical axis of the crystal and transforms the beam of reflected light to a ring of light having a periphery, each point of which has a different polarization plane. A detector array detects respective points along the periphery of the ring and a processing unit is coupled to the detector and is responsive to signals thereby for determining optical properties of the object.
