For the purpose of space exploration and aircraft technologies, researchers have explored travelling at hypersonic speeds, which entails attaining speeds over Mach 5, more than five times the speed of sound. This puts a huge strain on the aerodynamic and thermal designs of vessels and components. To test components and their capability to withstand airflows at such velocities, the University of Manchester in the United Kingdom have combined their hypersonic wind tunnel with a thermal imaging camera from FLIR Systems.
A new report from FLIR Systems describes how Norwegian waste treatment company - Lindum Ressurs og Gjenvinning AS has successfully implemented a FLIR GF320 gas camera to spot methane leaks, prevent uncontrolled gas venting and keep the air clean at and around its landfill sites. Using the FLIR camera as both a maintenance and safety tool - Lindum has made estimated savings of more than Euro 12,000 per year and has been able to reduce the foul odour nuisance considerably.
In laser sensor and measurement applications the challenges of the design of fast driver circuits is a very demanding task. This white paper describes the design of fast driver circuits, PCB layouts and optical measurement considerations, as well as a solution to achieve an ideal design for pulses as short as 2.5ns.
We report measurements of dynamic (ac) electrical conductivity in borosilicate glasses doped with the semiconductors CdSxSe1-x and AgI in a wide range of frequencies and temperatures. The concentrations of homogenously dissolved dopants are governed by the heat treatment conditions of the glass samples leading to a creation of CdSSe and AgI nanocrystals. The ac conductivity rises with increasing average size of the CdSSe nanocrystals, in contrast to the case of the metal halide doped borosilicate glasses.
Thermal imaging cameras allow researchers to not only see volcanic heat, but also to get non contact temperature readings from a safe distance, which keeps the researchers out of harm’s way.
