Abstract
PURPOSE: To improve the reconstruction accuracy of hologram by controlling the number plate position through detecting information marks for position reference of hoolgram recorded on a rotating hologram number plate.
CONSTITUTION: When one part of the principal luminous flux obtained by some means such as a half mirror in a recording time is made into an image through a position information slit or the like, information mark IMi for position reference of hologram is recorded on an angle position corresponding to hologram Hi on hologra trap T1... of a rotating hologram number plate 17. At the time of reconstruction of hologram Hi, a number plate 17 is controlled of its position by detecting the mark IMi with a photocoupler, then a position of the corresponding hologram H1 is controlled, thus enabling that the reconstruction of hologram becomes in a higher degree of precision without occurence of disturbances such as crosstalk.
