Photoacoustics is a non-ionizing, functional imaging modality capable of generating high contrast images of optical absorption at depths significantly greater than traditional optical imaging techniques.
2.
Therefore, if high contrast images are to be obtained, then only a few frames can be used; while for long movies, each frame will be of very low contrast.
3.
Kasdin's work on shaped pupil coronagraphy, one of the techniques being developed for WFIRST, has demonstrated high contrast imaging over a restricted field of view near a bright object such as a star.
4.
"' Aperture Masking Interferometry "'is a form of speckle interferometry, that allows diffraction limited imaging from ground-based telescopes, and is a planned high contrast imaging mode on the James Webb Space Telescope.
5.
That technology can produce a bright, high contrast image with a minimum of electromagnetic radiation, unlike a CRT . The size, brightness, and contrast of the screen are more critical to preventing eyestrain than your distance from it.
6.
Her graduate film " The Solitary Sandpiper " ( short film ), blending dream and reality and fantastic visual landscapes, where she worked innovatively to create a distinct color palette with special processing techniques on negative, such as " Bleach bypass " to create desaturated, high contrast images, would be the hallmark of her feature film " Ballad of Rustom " again in 2013 and define her keen interest in image making in cinema.
