Abstract
A cylindrical rainbow hologram is studied with a view to widening the horizontal viewing zone by using some unique mirror elements. The experimental result is compared with the calculation in reference to image blur and visual field restriction, both of which are caused by the fact that the rainbow hologram takes the shape of a cylinder. As a result, a 10-cm diam cylindrical rainbow hologram is made, from which the reconstructed image is observed in a 360° horizontal direction.
