Spatial light modulators
TL;DR: Near real-time reusable spatial light modulators for coherent optical data processing are reviewed and the PROM, liquid crystal, and electron beam addressed DKDP and oil film light valves appear to be the most promising devices.

Digital flashing tomosynthesis: a promising technique for angiocardiographic screening
TL;DR: This system is feasible for both an ambulatory basis to allow high-volume cardiovascular angiographic screening by only one X-ray snapshot, and for quantification of natural progression or potential regression of coronary artery disease resulting from interventional or pharmacological therapy.

Application of a Fresnel zone plate to gamma-ray imaging.
TL;DR: The fundamental principles of holography were first set forth by Gabor in 1948 and this technique has now been applied to imaging gamma-ray sources at the suggestion of Barrett.

X-Ray and gamma-Ray Imaging with Multiple-Pinhole Cameras Using a posteriori Image Synthesis.
G. Groh,G. S. Hayat,G. W. Stroke +2 more
TL;DR: An image having considerably increased SNR compared with a single pinhole camera image of starlike sources, may be synthesized from the multiplicity of images recorded at x-ray and gamma-ray wavelengths with the multiple-pinhole camera proposed by R. H. Dicke, using the method of extended-source Fourier-transform holography.
