HOLOCAM



A compact imaging system, which allows to measure the local phase of light per pixel (phase-precision = bit-quantisation, i.e. a 8 bit detector yields a precision of approx. 0.01 rad).

The HOLOCAM has been successfully tested in the laboratory. It works without reference beam.

The HOLOCAM opens up a new quality in optical vision.

INNOVATION

 

 

The HOLOCAM has been made possible by two major improvements:

 

1) a new way to generate interferograms by a 3D field transport which transforms the fields by "winding" them. The winding can be modelled exactly.

 


2) a new representation of the interference pattern as a linear function of the (unknown) phase. The phase-solution is obtained by solving an equivalent problem: finding the lowest energy state in a linear system. This approach is stable, local and does not use any approximation.

 

 

 

REFERENCE BEAM

 

In digital holography (as is the case here), the omnipresent reference beam is a historical burden, without further use. It limits precision, complicates or hinders the setup. The IFE invention has eliminated the reference beam.
