Mining. Total stations are the primary survey instrument used in mining surveying. A total station is used to record the absolute location of the tunnel walls, ceilings (backs), and floors, as the drifts of an underground mine are driven. The recorded data are then downloaded into a CAD program and compared to the designed layout of the tunnel.
Topcon. Subsidiaries. 19. Website. http://www.sokkia.com. Sokkia level. Sokkia Co., Ltd. was founded in 1920 as Sokkisha in Japan. It makes measurement instruments for the surveying, construction and industrial measurement industries. In 2008 Sokkia was acquired by Topcon, but still maintains a separate brand.
Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers. Light confined in the cavity reflects multiple times, producing modes with certain resonance frequencies.
Laser communications in deep space will be tested on the Psyche mission to the main-belt asteroid 16 Psyche, launched in 2023. The system is called Deep Space Optical Communications (DSOC), and is expected to increase spacecraft communications performance and efficiency by 10 to 100 times over conventional means.
Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
With a suitable range of periods, output wavelengths from 700 nm to 5000 nm can be generated in periodically poled lithium niobate (PPLN). Common pump sources are neodymium lasers at 1064 nm or 532 nm. An important feature of the OPO is the coherence and the spectral width of the generated radiation.
As of 2013 there are 5 active laser laboratories at the CLF: Vulcan, Astra Gemini, Artemis, ULTRA, and OCTOPUS. The facility provides both high-power and high-sensitivity lasers for study across broad fields of science from atomic and plasma physics to medical diagnostics, biochemistry and environmental science.
