Abstract

PURPOSE: To enable two kinds of different information to be read without operating any select switch by controlling the incident light of holograms by an electro-optic element thereby selecting images.
CONSTITUTION: Incident light from the direction of the arrow 3 is modulated by a polarizing plate 4 and liquid crystal 5, after which it enters holograms 6. The holograms 6 are divided to the patterns similar to those of the driving electrodes 7 of the liquid crystal and are recorded with respectively different images. Incident light to the holograms 6 is controlled by controlling the voltage to be applied to the electrodes 7 and 8 and the images visible in the holograms are selected by the voltage applied to the electrodes 7a and 7b.
