Fiber-coupled LWIR hyperspectral sensor suite for non-contact component surface temperature measurements

A Fiber Optical Sensor For Non–Contact Vibration Measurements

Vibration tests are widely employed in many industrial fields, and in particular in aerospace industry to evaluate the mechanical behavior of parts for aircrafts and satellites. Usually, these tests are carried out with shakers, while inertial accelerometers are used to measure the shaker table acceleration from which the vibration amplitude is computed. Some applications require the measuremen...

Characterization of Gaseous Effluents from Modeling of LWIR Hyperspectral Measurements

Longwave Infrared (LWIR) radiation comprising atmospheric and surface emissions provides information for a number of applications including atmospheric profiling, surface temperature and emissivity estimation, and cloud depiction and characterization. The LWIR spectrum also contains absorption lines for numerous molecular species which can be utilized in quantifying species amounts. Modeling th...

Non - contact surface charge / voltage measurements

Methods of measurements of surface electric charges and potentials using electrostatic fieldmeters and voltmeters are discussed. The differences and similarities between those methods are presented. The AC-feedback voltmeter is also described as an unique method that combines advantages of both fieldmeters and voltmeters.

Non-contact surface wave measurements on pavements

In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. Quality control of asphalt concrete pavements is crucial to verify the specified properties and to prevent pre...
