Abstract

Multiplanar object 10, shown in cross-section, is illuminated by light source 11 and its image is transmitted through optical system 12. The image is focused on viewing screen 13 from which it is viewed by an observer. Lens system 12 is comprised of two subsystems show n as lenses 14 and 15. The latter are automatically reciprocated by devices, not shown, at or above the flicker rate with respect to object 10. The respective reciprocating cycles of lenses 14 and 15 are in phase and have the same periodicity. The stroke of lens 14 is relatively shorter than the stroke of lens 15. Lens 14 provides high resolution of the image even though the focal planes of object 10 are undefined. Reciprocating lens 15 provides a uniform magnified image size of the object being viewed.

Multiplanar object 10, shown in cross-section, is illuminated by light source 11 and its image is transmitted through optical system 12. The image is focused on viewing screen 13 from which it is viewed by an observer. Lens system 12 is comprised of two subsystems show n as lenses 14 and 15. The latter are automatically reciprocated by devices, not shown, at or above the flicker rate with respect to object 10. The respective reciprocating cycles of lenses 14 and 15 are in phase and have the same periodicity. The stroke of lens 14 is relatively shorter than the stroke of lens 15. Lens 14 provides high resolution of the image even though the focal planes of object 10 are undefined. Reciprocating lens 15 provides a uniform magnified image size of the object being viewed. At screen 13, a magnified image of the object with high resolution is provided.
