The self-imaging phenomenon offers the possibility of implementing simple yet versatile optical processors. For example, it can be used for setting economical interferometers, or simple spectroscopes, and lensless spatial filters, or for performing optical correlations, and for implementing optical synthesizers.

Lensless photography of gratings
Strain, 1971A technique is described for the preparation of contactâcopy prints of gratings by means of reflex photography. The authors suggest that the method gives increased contrast and definition compared with classical methods of preparing prints.

PHYSIOLOGIC LENSLESS SPECTACLES
Archives of Ophthalmology, 1934For a long time the following facts have been known : Light passing through a small hole or a transparent spot in an opaque surface may, by virtue of its rectilinear propagation, be caused to form sharply defined images on a surface or screen of suitable character. Simple and practical cameras have utilized this principle.

The achieved imaging results are presented and discussed in this chapter. Using digital in-line holography amplitude and phase-contrast imaging in the extreme ultraviolet on cell-like specimen is presented. This is followed by experiments on coherent diffraction imaging at the Abbe limit demonstrating unprecedented relative resolution.
