... To align the interferometer, align the two laser spots so that they are on top of each other. Once the spots are aligned, defocus the laser so that the beam is about 4cm diameter at the screen. Final adjustment is through the screws on the back of the adjustable mirror. The spots should flicker or l ...

... In this simplified example* let’s say we have 100 pixels across the width of the monitor. If we display 25 mm of anatomy in those 100 pixels, 4 pixels will be used to display each mm of anatomy. It takes 2 pixels to display a line pair (one pixel for the line and one for the space). Therefore, in th ...

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.""
