Title: Innovations of Yrjo Koskinen
Introduction
Yrjo Koskinen is a notable inventor based in Helsinki, Finland. He has made significant contributions to the field of gas measurement technology. With a total of 3 patents, his work focuses on enhancing the accuracy and efficiency of gas concentration measurement methods.
Latest Patents
One of his latest patents is a method of controlling a short-etalon Fabry-Perot interferometer used in an NDIR measurement apparatus. This method involves generating a measurement signal using a radiant source, which is then provided to a sample point containing a gas mixture. The measurement signal undergoes bandpass filtering with an electrically tunable Fabry-Perot interferometer using at least two wavelengths of the interferometer passband. The filtered measurement signal is detected by a detector after passing through an optical filter component. During the measurement cycle, the passband frequency of the interferometer is controlled to coincide at least partially with the cutoff wavelength range of the optical filter component.
Another significant patent is a single-channel gas concentration measurement method and apparatus. This method employs a radiant source to generate a measuring signal directed to a measurement object containing a gas mixture. The measuring signal is bandpass filtered using at least two passband wavelengths, and the filtered measuring signals are detected by a detector. The bandpass filtering step is implemented by a single electrostatically tunable, short-resonator Fabry-Perot interferometer.
