SIMULATOR HAVING AN INFINITE-DEPTH-OF-FIELD OPTICAL PICKUP

An optical pickup having a final imaging lens with means for tilting the final lens about its rear nodal point to maintain registration of the optimum image plane resulting from varying object plane orientations. This technique increases the depth of field without affecting the f-number of the optic...

Zusammenfassung:	An optical pickup having a final imaging lens with means for tilting the final lens about its rear nodal point to maintain registration of the optimum image plane resulting from varying object plane orientations. This technique increases the depth of field without affecting the f-number of the optical pickup system or introducing distortions.
