- Abstract:
- A system is proposed that employs a spatial light modulator as a differentiation filter to measure the phase of an optical wavefront. The pattern, position and orientation of the filter can be controlled electrically. This system measures the phase derivative of a wavefront that passes through a transparent phase object. The 3D shape of the object can be calculated by integrating the phase derivative.
