Title: Optical vibration detection spectral analysis assembly and method for detecting vibration in an object of interest

Abstract

A vibration detection assembly is described which includes an emitter of light which has object and reference beams, the object beam reflected off of a vibrating object of interest; and a photorefractive substance having a given response time and which passes the reflected object beam and the reference beam, the reference beam and the object beam interfering within the photorefractive substance to create a space charge field which develops within the response time of the photorefractive substance.

Spectral analysis method for detecting an element

Patent Blackwood, Larry G [Idaho Falls, ID]; Edwards, Andrew J [Idaho Falls, ID]; Jewell, James K [Idaho Falls, ID]; ...

A method for detecting an element is described and which includes the steps of providing a gamma-ray spectrum which has a region of interest which corresponds with a small amount of an element to be detected; providing nonparametric assumptions about a shape of the gamma-ray spectrum in the region of interest, and which would indicate the presence of the element to be detected; and applying a statistical test to the shape of the gamma-ray spectrum based upon the nonparametric assumptions to detect the small amount of the element to be detected.

Process for the reconstruction of three-dimensional images of an area of interest of an object comprising the combination of measurements over the entire object with measurements of an area of interest of said object, and appropriate installation

Patent Azevedo, Stephen [Livermore, CA]; Grangeat, Pierre [Saint Ismier, FR]; Rizo, Philippe [La Tronche, FR]

Process and installation making it possible to reconstitute precise images of an area of interest (2) of an object (1) by reducing the errors produced by the contribution of the compliment of the object. A first series of measurements is carried out, where a conical beam (10) only takes in the area of interest of the object (2) and this is followed by a second series of measurements in which the beam takes in the entire object. A combination of the measurements of the two series is carried out in order to make them compatible and obtain a more accuratemore » image of the area of interest (2). « less

Method and apparatus for measuring surface movement of a solid object that is subjected to external vibrations

Patent Schultz, Thomas J [Maumee, OH]; Kotidis, Petros A [Waban, MA]; Woodroffe, Jaime A [North Reading, MA]; ...

A system for non-destructively measuring an object and controlling industrial processes in response to the measurement is disclosed in which an impulse laser generates a plurality of sound waves over timed increments in an object. A polarizing interferometer is used to measure surface movement of the object caused by the sound waves and sensed by phase shifts in the signal beam. A photon multiplier senses the phase shift and develops an electrical signal. A signal conditioning arrangement modifies the electrical signals to generate an average signal correlated to the sound waves which in turn is correlated to a physical ormore » « less
