The Photographic Emulsion Layer as a Three-Dimensional Recording Medium,ring layer into account. The characteristics of interest are the density (D), the granularity (G) and the modulation transfer function MTF. Here MTF is concerned with the distribution of the exposing light in the emulsion layer, whereas D and G describe the nature of the resulting developed granular

Optical Aperture Synthesis Producing High-Resolution Photographs by Incoherent Superposition of Low by simple photographic synthesis of the ‘high-resolution’ image in a single photograph, exposed successively through sets of small apertures, placed successively to generate the spatial frequency components of the desired large aperture..The high-resolution “full spatial-frequency range” optical im

Imaging with Low-Redundancy Arrays,trum of an incoherent object.. Stated another way, a certain spatial-frequency redundancy is inherent to such a system, with low spatial frequencies being weighted more heavily than high spatial frequencies. In this paper we propose that it may sometimes be desirable to destroy this redundancy by in

Optical Transfer Function Measurement by Holographic Techniques,oherent optical system is represented by . which is a complex function of the spatial frequency s and t. OTF is equivalent to the autocorrelation of the pupil function f(u,v) of an optical system as . In addition, there is the Fourier transform relation between OTF and the point spread intensity h(x

Holography Using an Extended Spatially Incoherent Source,atial and time coherence of the source. In 1967, Leith and Upatnieks made a hologram of very excellent quality with their achromatic fringe system (ref.1). They placed a photographic plate at the image plane of a grating and recorded a hologram between two beams of different orders of diffraction, i

Application of Holographic Interferometry to Mechanical Experiments,is not restricted only to an object with specularly reflecting surfaces. Another merit is the capability of time shearing interferometry. A wave front from an object can be compared not with any reference wave front but with that of the object itself in different states. Such advantages make the int

Experimental Aspects of Holographic Interferometry,ording of high speed elusive phenomena, aerodynamic visualization, non-destructive testing, and contouring. All represent problems and applications which can be uniquely solved by holography with state-of-the-art laser illuminators and some new optical systems insensitive to the incoherence of these
