GasVue® Backscatter Absorption Gas Imaging

For 10 years, Alan Dewey was the top electronic engineer at Laser Imaging Systems, Inc.  We designed and manufactured GasVue® Backscatter Absorption Gas Imaging Systems.  We designed infra-red scanners, video pre-amplifiers for infra-red detectors, laser control systems, laser temperature control to 0.02 oC.  We know the challenges and limitations of designing such sophisticated systems for industrial use.  We know how to make repeatable CO2 laser grating adjustments down to 7 mm.  This is done with stepper motor drive and LVDT feedback. We also have experience designing class 4 laser systems to comply with C.D.R.H. regulations.  GasVue® systems used DC excited CO2 waveguide laser.  Early systems were operated with water chillers and a dc heater around the laser tube.  Later, direct cooling by Peltier thermoelectric modules resulted in much lighter and manueverable systems.
