Holography and Digital Holography Microscopy (DHM)

Abstract:
Holography was invented in 1947 by Dennis Gabor who received Nobel Prize in 1971 for his work where as before microscopy affected only image variations of intensity as with a photograph. Gabor invention made it possible to record not only intensity but also light phase.

In conventional microscope the object is lead by a conventional light source and enlarged by a lens system. The image shows only contrast in intensity, no accurate 3D or vertical measurement is possible.

In holographic microscopy the beam from a coherent light source or laser is split into two beams. One illuminating the object itself and the other providing a reference beam which when recombine with the other beam creates a phase interference that is registered on the hologram plate.
