Research Abstract	Objects of Project : Trial manufacturing of holographic grating with laser and dichromate-geratine Application of holographic grating (hologram) to measurement. Merits of dichromate-geratine : Grainless grating (hologram). High S/N ratio grating. Highdiffraction efficiency. Demerit of dichromate-geratine : Low sensitivity especially at low spectral frequency. Results : High diffraction efficiency grating ( more than 75 % ). Sensitization effect ( 10mJ/cm at 488nm wavelength ). Application to beam splitter of interferometer. High quality white light real-image refrection hologram.
