  • Photoacoustic spectroscopy system
    Patent number: 7808640
    Abstract: A system for providing photoacoustic spectroscopy. A light source having a quantum dot filter may provide a band of infrared light which is to be reflected by a lamellar grating to a photoacoustic chamber. The light may be modulated by the grating. The chamber may contain a sample of fluid for which spectral information is sought. A sensor may detect acoustic pressures in the chamber which indicate the spectral information. Signals from the sensor may be processed and displayed. Identification and concentration of certain substances in the fluid may be obtained.
    Type: Grant
    Filed: July 30, 2008
    Date of Patent: October 5, 2010
    Assignee: Honeywell International Inc.
