Patent number: 10627522Abstract: The invention is directed to a device and method for conducting measurement of a Doppler shift caused by molecular and aerosol movement while simultaneously providing measurement of temperature using LIDAR. The device incorporates a light source; and a Fabry-Perot etalon having a resonant cavity formed with two plane parallel reflecting surfaces, wherein the light source is positioned relative to the a Fabry-Perot etalon such that light is injected into a plane parallel resonant cavity of the Fabry-Perot etalon at an angle of incidence other than normal to the reflecting surfaces. The Fabry-Perot etalon may be formed with each of the parallel reflecting surfaces having different reflectivities. The light source may be positioned to direct the light to bypass a first reflective surface of the plane parallel resonator cavity, and/or implemented using a divergent light source.Type: GrantFiled: March 12, 2015Date of Patent: April 21, 2020Assignee: Michigan Aerospace CorporationInventors: Paul Byron Hays, Scott K. Lindemann

Patent number: 8866322Abstract: A magnitude and direction, or a measure responsive thereto, of a velocity (V) of a first portion (17) of an atmosphere (20) are determined from at least first and second portions of scattered light (30) generated along a common beam of light (28) within the first portion (17) of the atmosphere (20) and received along linearly independent directions at locations that are relatively remote with respect to one another, at least one of which is relatively remote from a source (11) of the beam of light (28).Type: GrantFiled: July 29, 2010Date of Patent: October 21, 2014Assignee: Michigan Aerospace CorporationInventors: Peter Tchoryk, Jr., Charles J.

Patent number: 8810796Abstract: A portion of a first portion of light (13, 90, 90?) from a source of light (11) is masked by a mask (138), and the resulting masked first portion of light (90?) is combined using a beam splitter optic (136) with at least one second portion of the light (30) that had been subject to scattering by a medium (20, 20?, 20?). The mask (138) is configured so that interference patterns (104, 47) generated from the first and at least one second portions of light are substantially mutually exclusive even though those interference patterns (104, 47) would otherwise overlap one another absent the mask (138).Type: GrantFiled: December 24, 2010Date of Patent: August 19, 2014Assignee: Michigan Aerospace CorporationInventors: Paul Byron Hays, David Michael Zuk

Patent number: 8797550Abstract: A fringe pattern from an interferometer is imaged onto a digital micromirror device containing an array of micromirrors in an associated pattern of pixel mirror rotational states that provide for sampling the circular fringe pattern in cooperation with one or more associated photodetectors, so as to provide for generate a corresponding set of associated complementary signals. A plurality of different sets of associated complementary signals generated for a corresponding plurality of mutually independent associated patterns of pixel mirror rotational states are used to determine at least one metric associated with the circular fringe pattern.Type: GrantFiled: October 19, 2011Date of Patent: August 5, 2014Assignee: Michigan Aerospace CorporationInventors: Paul Byron Hays, David Keith Johnson, David Michael Zuk, Scott Kevin Lindemann

Patent number: 7522291Abstract: At least one second beam of light from a first beam of light generated by a laser is directed into an atmosphere. Light therefrom scattered by molecules or aerosols in the atmosphere is collected by at least one telescope as at least one light signal, which together with a reference beam from the first beam of light are simultaneously processed by a Fabry-Pérot etalon, and resulting fringe patterns are imaged onto a detector adapted to output a resulting at least one signal responsive thereto.Type: GrantFiled: October 29, 2007Date of Patent: April 21, 2009Assignee: Michigan Aerospace CorporationInventors: Paul Byron Hays, Charles J.
