Title: Optical filter for flash lamps in pulsed thermal imaging

Abstract

An optical filter made from a borosilicate optical material is provided for flash lamps used in pulsed thermal imaging. The filter substantially eliminates the infrared radiation from flash lamps to allow for accurate detection of surface temperature during entire pulsed thermal imaging tests.

Rapid flash lamp

Patent Gavenonis, Thomas L.; Hewitt, William H.

A method and apparatus for providing low peak time and pulse width actinic energy from a lamp by varying the input energy of a capacitive ignition circuit having relatively high voltage to the lamp. The lamp comprises a pair of electrodes disposed within a light transparent envelope in which a combustible and an oxidizing gas reaction combination is located. The combustible is preferably shredded zirconium which is in contact with and provides an electrical discharge path between the electrodes. The gas is preferably pressurized oxygen.

Tunable coherent light filter for optical sensing and imaging

Patent Wasserman, David; Shaner, Eric A.

Systems and methods are provided for filtering coherent infrared light from a thermal background for protection of infrared (IR) imaging arrays and detection systems. A Michelson interferometer is used for coherent light filtering. In an implementation, a system includes a fixed mirror, a beam splitter, and a moving mirror which can be controlled translationally, as well as tip/tilt. The Michelson interferometer may be used as an imaging system. For imaging applications, a system may comprise a tunable array of micro-electromechanical systems (MEMS) mirrors. A mid-wave IR interferometer with electronic feedback and MEMS mirror array is provided.

Method for thermal tomography of thermal effusivity from pulsed thermal imaging

Patent Sun, Jiangang

A computer-implemented method for automated thermal computed tomography includes providing an input of heat, for example, with a flash lamp, onto the surface of a sample. The amount of heat and the temperature rise necessary are dependent on the thermal conductivity and the thickness of the sample being inspected. An infrared camera takes a rapid series of thermal images of the surface of the article, at a selected rate, which can vary from 100 to 2000 frames per second. Each infrared frame tracks the thermal energy as it passes from the surface through the material. Once the infrared data ismore » « less
