Abstract (en)
A simplified, cost effective optical apparatus for solid state photorecording of optical images with enhanced resolution. The optical apparatus of the invention includes an array of optical apertures (203; 303; 503) and a plurality of portions of a phosphorescent material (209). Each portion is optically coupled to a respective one of the apertures. The apertures are exposed to an optical image (103; 403) so as to record the image in the plurality of portions of the phosphorescent material. A number of the apertures of the invention is large, preferably within a range of approximately one million to seven million apertures. For example in a preferred embodiment the number of the apertures is approximately six million apertures. Preferably, the optical apertures are microscopic optical apertures. For example, each aperture has a respective width dimension within a range of approximately ten to fifty microns. Preferably, the respective width dimension of each aperture is approximately twelve microns. <IMAGE>
