focusing by diffraction
71Pinhole camera — A pinhole camera is a very simple camera with no lens and a single very small aperture. Simply explained it is a light proof box with a single hole in one side. Light from a scene passes through this single point and projects an inverted image on …
72Optical coherence tomography — Intervention Optical Coherence Tomography (OCT) image of a sarcoma MeSH …
73X-ray microscope — An X ray microscope uses electromagnetic radiation in the soft X ray band to produce images of very small objects. Unlike visible light microscopes, X rays do not reflect or refract easily, and they are invisible to the human eye. Therefore the… …
74Atomic beam — is special case of particle beam; it is the collimated flux (beam) of neutral atoms.The imaging systems using the slow atomic beams can use the Fresnel zone plate (Fresnel diffraction lens) of a Fresnel diffraction mirror as focusing element. The …
75Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… …
76David Pritchard (physicist) — David E. Pritchard is physics professor at the Massachusetts Institute of Technology (MIT). Professor Pritchard carried out pioneering experiments on the interaction of atoms with light that led to the creation of the field of atom optics. His… …
77Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance — NOTOC The Airborne Real time Cueing Hyperspectral Enhanced Reconnaissance, also known by the acronym ARCHER, is an aerial imaging system that produces ground images far more detailed than plain sight or ordinary aerial photography can.cite web… …
78Giacinto Scoles — (b. 1935 in Torino, Italy) is a European North American chemist and physicist who is best known for his pioneering development of molecular beam methods for the study of weak van der Waals forces between atoms, molecules, and surfaces. He… …
79Acoustic microscopy — Introduction = Acoustic microscopes employ very high or ultra high frequency ultrasound. These microscopes operate nondestructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks,… …
