Abstract

An infrared (10μm) wavefront is recorded holographically on a dynamic recording medium consisting of a thin oil film on a glass substrate. The phase hologram obtained is used to restore the information of the infrared wavefront or alternatively as a diffraction grating for a visible reconstruction beam. This property is applied to implement a single hybrid interferometer (Michelson or Mach-Zehnder) for the simultaneous testing of infrared and/or visible optical components. Experimental results both for visible and infrared components (parallel plate, lens) confirm the usefulness of this interferometer.
