Latest Patents

One of his latest patents is a method and apparatus for detecting a gas concentration with reduced pressure dependency. This invention relates to a method that makes the measurement of a trace gas concentration invariant or at least less affected by pressure variations in the gas and atmospheric pressure changes. The method neither requires a pressure sensor nor a pressure calibration routine. Furthermore, it can be applied to other gas species present in the background gas or to the background gas itself that cross-interfere with the target gas of interest. This allows for the removal of any pressure dependency of cross-interference parameters of other gas species and/or the background gas. The new method for accurately measuring a gas concentration is based on optimizing the wavelength modulation amplitude of the laser to minimize pressure dependency.

Another significant patent is for a laser diode structure with reduced interference signals. This invention is designed for generating a collimated or divergent laser beam, preferably for application in gas detection. The laser diode is arranged in a closed housing, which comprises a housing bottom, an exit window, electrical connections, a temperature control device for the laser diode, and an optical element for influencing the laser beam. The temperature control device carrying the laser diode is arranged on the housing bottom, and the optical element is positioned at a distance from the laser diode. The invention proposes an electrically controllable power device for the cyclic alteration of the position and/or alignment of the optical element in relation to the laser diode. This oscillating motion of the optical element helps in time-averaging the etalon and/or self-mixing effects caused by the back-reflections of the laser beam in the housing, thereby reducing the optical noise of the laser diode structure.
