Abstract :	[en] The holographic camera developed by CSL was aimed at observing of medium to large opaque scattering objects. In the recent times, we received an increasing demand of measurement on small objects (a few centimetres wide) or micrometric systems (MEMS). In the last case, most of them are specular objects ranging to a few microns. The imaging and illumination systems of our holographic device was naturally not adapted to such new objects. Therefore we decided to study a new optical extension to the current system which matches these new needs. Nevertheless the type of displacement that can be measured remain similar to the ones covered by the previous system. We present various examples of applications brought by industrial partners.
