Title: Methods and systems for imaging bulk motional velocities in plasmas

Abstract

A method and apparatus for imaging the distribution of bulk motional velocities in plasmas such as inertial confinement fusion (ICF) implosions. This method and apparatus use multiple narrow-band x-ray crystal imaging systems, one or more of which have a bandpass tuned to lie within the Doppler-broadened emission line profile of a suitable plasma emission line. Crystals tuned on the one end of the profile will preferentially reflect x-rays from plasma ions moving towards the crystals, while crystals tuned to another end of the profile will preferentially reflect x-rays from plasma ions moving away from the crystals.

System and method for generating motion corrected tomographic images

Patent Gleason, Shaun S [Knoxville, TN]; Goddard, Jr., James S. (Knoxville, TN)

A method and related system for generating motion corrected tomographic images includes the steps of illuminating a region of interest (ROI) to be imaged being part of an unrestrained live subject and having at least three spaced apart optical markers thereon. Simultaneous images are acquired from a first and a second camera of the markers from different angles. Motion data comprising 3D position and orientation of the markers relative to an initial reference position is then calculated. Motion corrected tomographic data obtained from the ROI using the motion data is then obtained, where motion corrected tomographic images obtained therefrom.

Apparatus for producing an acoustic image of an object according to the present invention may comprise an excitation source for vibrating the object to produce at least one acoustic wave therein. The acoustic wave results in the formation of at least one surface displacement on the surface of the object. A light source produces an optical object wavefront and an optical reference wavefront and directs the optical object wavefront toward the surface of the object to produce a modulated optical object wavefront. A modulator operatively associated with the optical reference wavefront modulates the optical reference wavefront in synchronization with themore » « less
