Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To provide an easily manufacturable and compact polarization phase modulation element and an integrator optical system with a high utilization factor of light using the same. SOLUTION: Two coherent luminous fluxes with mutually the same wavelength are made incident on a photosensitive material (17) capable of recording exposure amount as modulation of a refractive index symmetrically with respect to a normal (X2) to a photosensitive material (17) surface. The photosensitive material (17) is exposed with interference fringes formed out of the two luminous fluxes. In this case the exposure is carried out by making the pitch of the interference fringes shorter than the used wavelength via a mask (M) so as to make a region on the photosensitive material (17) surface to be exposed form a specified pattern. The pattern becomes a structural birefringent region on which the interference fringes with the pitch shorter than the used wavelength are recorded as a refractive index distribution.
