DEVICE FOR MEASURING HOLOGRAM RECONSTRUCTION IMAGE BY VARYING VERGENCE OF INCIDENT WAVE METHOD FOR MEASURING HOLOGRAM RECONSTRUCTION IMAGE USING THE DEVICE COMPUTER READABLE MEDIUM FOR PERFORMING THE METHOD

摘要

According to the present invention, a device for measuring a hologram reproduction image using a convergence degree varying method of incidence light waves comprises: a light source array outputting incidence light waves at different output distances in a hologram film; and a camera photographing reproduction light waves for the incidence light waves passing through the hologram film, and measuring a hologram image for a specific focal distance reproduced by the hologram film. Thus, a plurality of holographic images having different focal distances can be sequentially measured at a fixed position by selectively lighting light sources constituting the light source array.
