Abstract: (2074 Views)
Phase reconstruction of a complex light field plays an important role in optics and microscopy. Here we introduce an iterative phase retrieval approach; this method is based on a simple configuration and is easy to work in relation to other holographic approaches and have a considerable sensitivity to phase reconstruction from microscopy objects. We implement it to measure phase profile of titanium diffused channel waveguide on the Lithium Niobate substrate, which is a uniaxial crystal, in and mode. Our results show the channel waveguide has different phase profile and consequently different refractive indexes in orthogonal polarization directions.
