Non-contact temperature measurement

Advances in Space Research, 1991
Three methods for noncontact temperature measurement are presented. Ideal gas thermometry is realized by using laser-induced fluorescence to measure the concentration of mercury atoms in a Hg-Ar mixture in the vicinity of hot specimens. Emission polarimetry is investigated by measuring the spatially resolved intensities of polarized light from a hot ...

Non-contact endoscopic temperature measurement

Optical Fibers and Sensors for Medical Diagnostics and Treatment Applications XX, 2020
We demonstrate a pyrometric contactless temperature sensor using a flexible fused silica fiber of 360 μm diameter for endoscopic/laparoscopic surgery equipment. The large bandwidth (up to several kilohertz), and the broad temperature range (from 35°C to 250°C) of the sensor can be instrumental for time-resolved analysis and control of laser ablation ...

Non-contact resistivity measurements

Proceedings, 1996
Resistivity method finds wide application in many countries for the problems of near-surface geophysics. Frequently at field work by a resistivity method some problems of galvanic contacts with the ground occurs, for example at rocky surfaces, on dry sand, in permafrost regions, on a snow and an ice surface, on asphalt and concrete in cities, etc.

Non-contacting distance measuring system

The Journal of the Acoustical Society of America, 1986
To determine if a pulsed beam system, typically an ultrasonic pulsed beam system, which is located externally of a motor vehicle is in operative condition, a transmitter (14) projects a beam to a fixed reflector (16) located on the vehicle, and one (19) of a group of timing stages (18; 19, 20, 21) evaluates the transit time to the reflector.

Non-contact surface roughness measurement

SPIE Proceedings, 1993
A noncontact optical profiler for measuring surface roughness is described. The system consists of a differential interference microscope with a polarization phase shifter CCD detector array video frame grabber and computer. Interferometric phaseshifting techniques are used to obtain surface slope information. The slope data is then integrated to yield
