The wavefront phase can be understood as the mathematical description of propagation direction of light rays. As light passes through transparent media or is reflected off a surface, the wavefront phase changes according to the refractive index of the media or the surface profile of the surface.
Wavefront Phase Imaging (WFPI)
WFPI is a sensor developed by Wooptix for acquiring high resolution wave front phase maps, with typical lateral resolution in the order of microns and amplitudes of phase resolution in nanometers. Unlike conventional wave front phase sensors, it is based on conventional imaging cameras and lenses. So any developer can assembly an optical arrangement to take advantage of Wooptix’s algorithm. The algorithm is as simple as it can be accessed worldwide through cloud , Wooptix can also provide an API for its use on most extended development environments such as Python or Matlab.
