Title: BIREFRINGENT LENS INTERFEROMETER
Abstract:
Techniques to improve image quality in holography utilizing lenses made from materials with non-quantized anisotropic electromagnetic properties, such as birefringent materials, to advantageously split an incoming beam of light into two coincident beams with different focal lengths that interfere with one another and thus create holograms free of electro-optical or pixelated devices are disclosed. The use of thin birefringent lenses is introduced. Corresponding systems, methods and apparatuses are described.
