61telescope — /tel euh skohp /, n., adj., v., telescoped, telescoping. n. 1. an optical instrument for making distant objects appear larger and therefore nearer. One of the two principal forms (refracting telescope) consists essentially of an objective lens… …
62Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
63Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …

66Supersonic transport — The Concorde supersonic transport had an ogival delta wing, a slender fuselage and four underslung Rolls Royce/Snecma Olympus 593 engines. A supersonic transport (SST) is a civilian supersonic aircraft designed to transport passengers at speeds… …
67Nantenna — Figure 1. Spectral irradiance of wavelengths in the solar spectrum. The red shaded area shows the irradiance at sea level. There is less irradiance at sea level due to absorption of light by the atmosphere. A nantenna (nanoantenna) is a… …
68Flash (photography) — The furious wing action of a Hummingbird Hawk moth is frozen by flash. The flash has given the foreground more illumination than the background. See Inverse square law A flash is a device used in photography producing a flash of artificial light… …
69Laser cutting — process on a sheet of steel. CAD (top) and stainless steel laser cut part (bottom) Laser cutting is a technology that uses a laser to cut materials, an …
70Diffuse reflection — For reflection of charged particles, see Scattering from rough surfaces. Diffuse and specular reflection from a glossy surface[1] Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many …
