Wavefront phase

The dark side of the light

The wave front phase is the mathematical description of propagation directionof light rays.

As light passes through transparent media or is reflected in a surface, the wave front phase changes according to the refractive index of the media or the surface profile of the surface.

"Never before the light could be studied in such detail.
This opens a whole new world of possibilities."
Juan Trujillo: Chief WFP project


Wooptix WFP is a new wave front phase sensor capable of achieving resolutions higher than any other wave front sensor.

A wave front sensor of such high resolution expands the possibilities of wave front sensing.
Until now, wave front sensing have been used to measure low order aberrations in optical designs.

The capacity of WFP to measure wave front phase without resolution limit enables measuring fine surface profiles and small scale aberrations that are not accessible with standard wave front sensors.

From the instrumental point of view, to implement WFP, is straightforward. It only needs one image sensor, placed in the pupil plane of the optical system.Then, one image is captured. From the intensity values of that image the wave front phase is computed.
