... held constant by a pressure regulator, and back pressure Pb (downstream the nozzle) is adjustable by a valve. If the downstream valve is closed, the entire nozzle is at a pressure equal to P0, and there is no flow. As the valve is slowly opened, the flow is at first subsonic, and follows a pressure ...

... coupler splits light launched into port 1 and a specific wavelength, λG, is reflected by the two identical gratings. These reflected signals interfere in the 3dB coupler in such a way that the signal is dropped and the back-reflected light intensity arriving at port1 is zero, providing the coupler i ...

Harold Hopkins (physicist)

Harold Horace Hopkins FRS (1918–1994) was a renowned British physicist. His Wave Theory of Aberrations, (published by Oxford University Press 1950), is central to all modern optical design and provides the mathematical analysis which enables the use of computers to create the wealth of high quality lenses available today. In addition to his theoretical work, his many inventions are in daily use throughout the world. These include zoom lenses, coherent fibre-optics and more recently the rod-lens endoscopes which 'opened the door' to modern key-hole surgery. He was the recipient of many of the world's most prestigious awards and was twice nominated for a Nobel Prize. His citation on receiving the Rumford Medal from the Royal Society in 1984 stated: ""In recognition of his many contributions to the theory and design of optical instruments, especially of a wide variety of important new medical instruments which have made a major contribution to clinical diagnosis and surgery.""
