  • Laser absorption detection enhancing apparatus and method
    Patent number: 4934816
    Abstract: The disclosure relates to an apparatus and method for increasing the sensitivity of laser absorption detection of gas phase atoms and molecular species within a gaseous medium. An active optical element in a laser absorption detection system is translationally (longitudinally) vibrated a selected amplitude along the optical axis and at a desired frequency to eliminate fringes produced by interference fringe producing optical elements. The vibration frequency is preferably asynchronous with other modulation frequencies in the system.
