NGP Inc. proprietrary method for real time monitoring of analytes named differential swept wavelength absorption spectroscopy, or DSWAS is covered by the U.S. Patent No. 9,784,674 B2 and by the Canadian Patent No. CA2904850C iGASTRAX is the instrument for real…
This is the spectrum of the tunable fiber optic laser built with two-cascaded Optune tunable optical filters (see Publications [1]). It has FWHM line width down to 41MHz, tuning range of 200+nm, tuning speed below 1ms across 200nm and linear…
The accuracy of camera calibration is key in overall accuracy of remote measurement equipment using digital cameras. By the time of reading this page, there are probably several thousand articles covering this subject in major libraries such as IEEE, SPIE…
This MATLAB 3D graph shows temperature distribution inside a hot metal plate moving at constant velocity, when a laminar flow of cold water impinges normal to its surface. The water-metal interface is on the bottom of the graph. This configuration…
The MFOS – Optical Layout diagram shows the optical layout of Michelson interferometer built with single mode optical fibers. The reference arm on bottom side has L1 length. The measuring arm on top side has L2 length. Two anchor points…
Laser measuring instruments have big market opportunity in structures monitoring by fiber optic sensing technologies. This video shows several structures already monitored by fiber optic sensors or having great potential to be monitored by fiber optic sensors. The actual cost…
Recovering from Noise the Response of Fiber Optic Sensors We work currently on an interrogator for fiber optic sensors targeted mainly to bare single mode optical fiber used as distributed fiber optic sensor. External perturbations such as local force or…
