An approach to achieve superresolution in confocal scanning microscopy
by using the singular-system approach to the inverse problem was rece
ntly proposed. It consists of using a specially designed mask that per
forms the task of data inversion by means of all-optical processing. W
e discuss an approximate binary form of such a mask that permits its p
ractical manufacture for use iri incoherent confocal microscopy. The p
erformance characteristics of such an approximate mask are compared wi
th those of an exact mask and with those of a conventional confocal sc
anning microscope. Although the resolution of the approximate microsco
pe is slightly inferior to the exact one, they are both still advances
over the conventional confocal one (the improvement of resolution bei
ng 65% and 70% respectively).
