Abstract

A method and system for viewing objects obscurred by intense plasmas or flames (such as a welding arc) includes a pulsed light source to illuminate the object, the peak brightness of the light reflected from the object being greater than the brightness of the intense plasma or flame; an electronic image sensor for detecting a pulsed image of the illuminated object, the sensor being operated as a high-speed shutter; and electronic means for synchronizing the shutter operation with the pulsed light source.

Electronic imaging system and technique

Patent Bolstad, J.O.

A system is described for viewing a weld site obscured by an intense plasma or flame comprising: a pulsed light source providing an illumination beam for illuminating the weld site, the peak brightness of the light reflected from the weld site being greater than the brightness of the intense plasma or flame; an electronic image sensor for detecting a pulsed image of the illuminated weld site, the sensor operating as a high-speed shutter; and electronic means for synchronizing the shutter operation with the pulsed light source.

SEM technique for imaging and measuring electronic transport in nanocomposites based on electric field induced contrast

Patent Jesse, Stephen [Knoxville, TN]; Geohegan, David B [Knoxville, TN]; Guillorn, Michael [Brooktondale, NY]

Methods and apparatus are described for SEM imaging and measuring electronic transport in nanocomposites based on electric field induced contrast. A method includes mounting a sample onto a sample holder, the sample including a sample material; wire bonding leads from the sample holder onto the sample; placing the sample holder in a vacuum chamber of a scanning electron microscope; connecting leads from the sample holder to a power source located outside the vacuum chamber; controlling secondary electron emission from the sample by applying a predetermined voltage to the sample through the leads; and generating an image of the secondary electronmore »« less

Motion artifact suppression technique of magnetic resonance imaging

Patent Pattany, P.M.; McNally, J.E.

This patent describes an apparatus for generating motion desensitized magnetic resonance images comprising: main magnetic field means for generating a generally uniform magnetic field through an image region; a radio frequency pulse means for selectively applying radio frequency pulses to the image region; a slice selection gradient control means for selectively applying magnetic field gradient pulse in a slice select direction across the image region; read gradient control means for selectively applying magnetic field gradient pulses across the image region in a read direction; a phase encode gradient control means for selectively applying magnetic field gradients in a phase encodemore »« less
Blood flow imaging using a CW NMR technique

Patent Moran, P.R.; Halbach, R.E.

In an NMR flowmeter which measures flow through an active region by applying a polarizing magnetic field having a relatively fixed magnitude in the active region and by applying a transverse excitation field within the active region to produce a transverse magnetization in paramagnetic nuclei located in the active region, and receiving the signal produced by the transversely magnetized paramagnetic nuclei, this patent describes an improved method comprising: applying a first contoured polarizing magnetic field at one boundary of the active region such that paramagnetic nuclei flowing into the active region through the boundary do so from a region ofmore »« less
