Jyrki K. Kauppinen was born in Finland in 1944. He was received his Bachelor of Arts degree in 1967, his Master of Science degree in Physics in1968, and the Ph.D. degree in 1975 from the university of Oulu. He started his academic career at the University of Oulu working in many positions from assistant to professor. The National Research Council of Canada appointed him a research fellow in 1980. Dr. Kauppinen was elected as senior research fellow at the Academy of Finland in 1981. He has also worked at the Technical Research Center of Finland and the Metrology Research Institute of Helsinki University of Technology. In 1990 he was a visiting scientist at the National Research Council of Canada and at Kansas State University. At present he is a professor of Physics at the University of Turku (since 1986), a docent in Physics at the University of Oulu, and a docent in Optical Measurement Technology at Aalto University in Espoo.
Professor Kauppinen has published about 180 papers in international scientific journals and he has presented about 150 conference presentations and about 60 invited lectures. He has written invited review articles in Encyclopedia of Applied Physics, in Encyclopedia of Spectroscopy and Spectrometry, in Spectrometric Techniques, in Optics Encyclopedia, and in Handbook of Vibrational Spectroscopy. His paper dealing with Fourier Self-Deconvolution has the highest citation number in the whole history of the Journal of Applied Spectroscopy. In 2001 Kauppinen and Partanen published a book Fourier Transforms in Spectroscopy (Wiley-VCH). He has 20 patents or patents pending.
He has been for example a member of the program and steering committees in the International Conferences on Fourier Transform Spectroscopy, a member of the working group of IUPAC for Unified Wavenumber Standards, a member of Finnish Academy of Science and Letters, and a member of the editorial board of Applied Spectroscopy Reviews. He was the chairman of the program committee and a member of the steering committee for the first International Conference of Advance Vibrational Spectroscopy ICAVS-1 held in Turku. He was also a member of the program and steering committees for ICAVS-2. He has received the International Bomem-Michelson Award in 1992 and the Innovation Award (the Foundation for New Technology) in 1999 and in 2005 for developing the commercial FTIR gas analyzer GASMET with Temet Instruments Ltd (later Gasmet technologies Ltd).
His varied research interests include high-resolution Fourier transform spectroscopy, development of high-resolution interferometers. He built his first high resolution FTIR spectrometer at the University of Oulu. This spectrometer was the fifth high resolution FTIR instrument in the world starting to record spectra in 1971. All the time the resolution of the spectrometer has been the highest one in the world. Later Dr. Kauppinen modified the interferometer using the first time home made cube-corner mirrors. The modified cube-corner interferometer achieved the resolution of 0.001 1/cm, which is still the highest practical resolution. At the University of Turku he has built a new cube-corner interferometer with a resolution of 0.0004 1/cm . Further, he has produced infrared wavenumber standards and studied a lot of rotation vibration spectra of molecules including all the greenhouse gases with his high resolution interferometer. He has developed the gauge measuring interferometer for the Finnish standard of length, low resolution stationary interferometers (without moving parts), small very stabile low resolution interferometers for IR, NIR, VIS, and UV such as Carousel-interferometer, Pendium interferometer, and Diamond interferometer, an automatic, commercial, portable FTIR gas analyzer GASMET.
Dr. Kauppinen has developed data processing by various sophistic mathematical methods such as resolution enhancement using Fourier Self-Deconvolution and the extrapolation of signals. Applications of the extrapolation to audio signals are commercialized in the company Noveltech Solutions. So three spinoff companies have been founded based on his research work. His latest innovation was an optical microphone using silicon cantilever as a pressure sensor. In the cantilever the movement of the free end is measured with a small interferometer with the precision smaller than picometer.This microphone has been used in photoacoustic spectroscopy to improve sensitivity. In Gasera Ltd there are a few commercial instruments based on his microphone. In principle, photoacoustic detection of gases is based on the greenhouse phenomenon in a small gas chamber. Typical detection limits in Gasera photoacoustic gas sensors are about 0.1 ppb with one second observation time. Drug sensors are even more sensitive than the dogs specially trained for drug tests.
