Machine vision refers to many technologies, software and hardware products, integrated systems, actions, methods and expertise. Machine vision as a systems engineering discipline can be considered distinct from computer vision, a form of computer science. It attempts to integrate existing technologies in new ways and apply them to solve real ...
Direct laser writing is a very popular form of optical maskless lithography, which offers flexibility, ease of use, and cost effectiveness in R&D processing (small batch production). The underlying technology uses spatial light modulating (SLM) micro-arrays based on glass to block laser pathway from reaching a substrate with a photoresist (in ...
The method allows for the exact and easy generation of very fine patterns with unlimited depth of field. Disadvantages are high cost of implementation, difficulties providing the ideal beam geometry, and laser typical effects like speckle noise and the possible self interference with beam parts reflected from objects. Typically, there is no ...
A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation.
The guidance system may serve also as a mediator for cooperative multiple robots. [1] [2] Examples of proof-of-concept experiments of directing a robot by a laser pointer are shown on video. [3] [4] Laser guidance spans areas of robotics, computer vision, user interface, video games, communication and smart home technologies.

Contoura Vision is the only technology where consistent success beyond 20/20 vision has been achieved in the majority of patients. More than 40% of the patients that were evaluated were able to read one line on the visual acuity chart more than a person with 20/20 vision, and 13.5% could read two additional lines.
As it was first built in 1974, SHIVA I consisted of four banks of capacitors arranged in a cross shape with the experimental chamber in the middle. The capacitors held 1 MJ at 100 kV, able to discharge them in 1 μs. Early experiments were hampered by problems with the implosion, but by 1976 successful implosions were being carried out. [2]
