摘要：
In an optical display apparatus including a hologram device and a light source, the hologram is a reflection-type hologram formed by: light having information of an object which is obtained by using light having passed through a slit; and reference light having an incident optical path different from that of the light having the information of the object, wherein a reconstructed image of the object is displayed by light from the light source.
