Method of making a hologram |
摘要 |
This specification discloses a method of making a hologram imaged substantially without aberrations during the use when the wavelength of a light during the making differs from the wavelength of a light during the use and having high diffraction efficiency. In order to eliminate any aberration occuring when the hologram is used in a light beam of a different wavelength and to obtain high diffraction efficiency, a making light beam is caused to enter a predetermined coaxial optical system from outside the axis thereof to impart a suitable aberration, and a hologram is formed on a hologram sensitive material by the making light beam.
