Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must

Anamorphic Stretch Transform (DAST) and its application to image compression. DAST is a physics-inspired transformation that emulates diffraction of the image through a physical medium with specific nonlinear dispersive property. By performing space-bandwidth compression‚ it reduces the data size required to represent the image for a given image quality. This diffraction-based compression is achieved through a mathematical restructuring of the image and not through modification of the sampling process

Important Personalities in Police Photography *Joseph Nicephore Niepce - was able to obtain camera images on papers sensitized with silver chloride solution in 1816.He invented a photographic process which he called "heliography" meaning "writing of the sun" *Louis Jacques Mande Daguerre - invented "Daguerreotype"‚ an early photograph produced on a silver or silver-covered copper plate.It formed an image directly on the silver surface of a metal plate.It was a positive process‚thus‚it yielded
