  • Photographic transparency for producing a lenticular array
    Patent number: 4028109
    Abstract: An apparatus and method are disclosed by which a processed photosensitive material can be provided with a lenticular surface with each lenticule having a predetermined profile. The lenticules are arranged relative to one another with such a degree of accuracy that any speckle and scintillation that might be produced when the processed material is utilized as an element of a transmission or reflection type screen is reduced to a minimum, if not completely eliminated. Once the exposure factors for the emulsion have been established, the exposure profile can be determined for a particular lenticule profile to be imaged onto the photographic material or emulsion. The exposure profile can be utilized to provide a transparency master target pattern which can be of a relatively large size.
