Optical scanning system for reading micro-image records

An optical system for reading a microrecord wherein a plurality of data sets are formed on the face of a planar record medium, each data set representing a reduced scale image of a distinct page of intelligence and being dissected into a multiplicity of data sub-sets which are dispersed on the medium in accordance with a predetermined pattern, the dispersed sub-sets which constitute the plurality of data sets being interlaced with each other whereby each data set occupies a distinct position on the medium and may optically be extracted therefrom, said optical system comprising an array of lensettes in parallel relation to the record medium, each lensette in the array being optically aligned with a respective correspondingly-positioned sub-set in a selected data set and being constituted by a reflective concave element and a reflective spherical element associated therewith to project an image of the sub-set to recreate the page represented by the selected data set.
