High-sensitivity photoacoustic leak testing.
The photoacoustic effect may be exploited for the detection and localization of gas leaks from otherwise sealed components. The technique involves filling the test component with a tracer gas, and radiating the component to produce photoacoustic sound from any leak site where tracer gas is present. This paper describes demonstration experiments utilizing 10.6-micro radiation from a carbon-dioxi...
متن کاملCurrent Trends in Leak Testing Technology
Leak detection techniques are not exclusively used for the vacuum products but are finding increasing applications in almost all industrial areas. Therefore, leak definition is evolving to accommodate the industry point of view. A leak always requires a flow of mass though the walls of a volume intended to be sealed. It usually results in escape or admission of liquids or gases from sealed comp...
متن کاملOptical Leak Testing of Hermetic Packages
A production leak test system using digital holography, Optical Leak Testing (OLT), has been developed for simultaneous gross and fine leak testing of hermetic semiconductor, MEMS and Optoelectronic devices. The technique has also shown the unique capability to leak test ceramic SMC’s on PCBs, even if conformal coated. Many devices are manufactured using welded, brazed or soldered metal lids wi...
متن کاملAdvances in photoacoustic noninvasive glucose testing.
We report here on in vitro and in vivo experiments that are intended to explore the feasibility of photoacoustic spectroscopy as a tool for the noninvasive measurement of blood glucose. The in vivo results from oral glucose tests on eight subjects showed good correlation with clinical measurements but indicated that physiological factors and person-to-person variability are important. In vitro ...
متن کاملAcoustic methods for leak detection and tightness testing
Air tightness testing has importance in industrial environments where in compressed air systems leaks account for a high percentage of energy loss. These losses can effectively be reduced by locating and repairing of leaks. Furthermore, tightness is a criterion for the quality of different kinds of seals and joints. For leak detection and tightness testing acoustic methods (passive and active) ...
