Temporal Thermal Imaging Method For Detecting Subsurface Objects and Voids

Номер: US20130322693A1
Автор: Nancy Kerr Del Grande
Принадлежит: Individual

A temporal thermal survey method to locate at a given area whether or not there is a subsurface object or void site. The method uses thermal inertia change detection. It locates temporal heat flows from naturally heated subsurface objects or faulty structures such as corrosion damage. The added value over earlier methods is the use of empirical methods to specify the optimum times for locating subsurface objects or voids amidst clutter and undisturbed host materials. Thermal inertia, or thermal effusivity, is the bulk material resistance to temperature change. Surface temperature highs and lows are shifted in time at the subsurface object or void site relative to the undisturbed host material sites. The Dual-band Infra-Red Effusivity Computed Tomography (DIRECT) method verifies the optimum two times to detect thermal inertia outliers at the subsurface object or void border with undisturbed host materials.

A tunable tunnel junction thermometry circuit includes a variable width tunnel junction between a test object and a probe. The junction width is varied and a change in thermovoltage across the junction with respect to the change in distance across the junction is determined. Also, a change in biased current with respect to a change in distance across the junction is determined. A temperature gradient across the junction is determined based on a mathematical relationship between the temperature gradient, the change in thermovoltage with respect to distance and the change in biased current with respect to distance. Thermovoltage may be measured by nullifying a thermoelectric tunneling current with an applied voltage supply level. A piezoelectric actuator may modulate the probe, and thus the junction width, to vary thermovoltage and biased current across the junction. Lock-in amplifiers measure the derivatives of the thermovoltage and biased current modulated by varying junction width.
