As shown in (a) and its partially enlarged view (b), two beams A and B from the same laser are respectively fed to the lenses 3 and 4, respectively.
When these two focused beams are made to interfere with each other in the localized space 5 in the photosensitive material 1 on the substrate 2, spatial interference fringes are formed in the part 5. While changing the relative angles of the beams A and B, the localized spaces 5 are moved in the photosensitive material 1 as shown by arrows 6 so that the optical systems 3 and 4 and / or the photosensitive material 1 or both are connected by interference fringes. hand,
The interference fringe distribution as previously calculated is recorded in the photosensitive material 1. This movement may be intermittent movement in the direction of the surface of the photosensitive material 1 or continuous movement. Alternatively, the interference fringes may be continuously moved in the surface direction. If the area 5 of the interference fringes is smaller than the film thickness of the photosensitive material 1, the movement in the film thickness direction is also performed. In this case, by changing the relative angle between the two laser beams A and B at the same time as the movement, the pitch of the interference fringes and the angle formed by the center line of the angle between them and the normal line of the photosensitive material surface are changed. Thus, the angle of the interference fringes in the photosensitive material can be changed.

By recording with precise control using a computer, for example, by correlating with the position of the area, arbitrary diffraction angle distribution characteristics of the condensing element, combiner for head-up display, spatial distribution color filter, etc., wavelength transmission or reflection An optical element having distribution characteristics and transmittance or reflectance distribution characteristics can be manufactured.

The positions of the laser beams A and B are illustrated in association with the positions while precisely controlling the position of the interference region by precisely controlling the position in the radial direction indicated by 11 and the height indicated by the arrow 12. The light source side is controlled and the angles of the laser beams A and B in the directions of arrows 8 and 9 are controlled so that the relative angle between them and the angle between the laser beam A and B and the normal to the surface of the photosensitive material become predetermined values. Control is performed to sequentially record in the light-sensitive material. Although a rotary table is used in FIG. 2, an XY stage may be used, or a method of moving a laser beam may be used.
