  • PHONON DISRUPTORS FOR INCREASED THERMAL RESISTANCE WITHOUT SACRIFICING ELECTRICAL SIGNAL QUALITY IN THERMAL SENSORS USING ALLOY AND INTERMETALLIC MATERIALS
    Publication number: 20220373395
    Abstract: Sensor interconnects and supports and methods of making them utilize phonon disruptors for increased thermal resistance while maintaining acceptable electrical signal quality in materials. Phonon disruptors include the use of an electrically conductive alloy material or intermetallic material of at least two or more elements to promote scattering of phonons. These materials are selected to scatter heat carriers while allowing electrons to pass through the material.

  • Apparatus and method to perform per-pixel microbolometer camera time constant measurements
    Patent number: 11231325
    Abstract: An apparatus to measure the time constant of microbolometer-type uncooled thermal imaging camera pixels on a per-pixel basis has been developed. The apparatus utilizes a longwave infrared laser and acousto-optic modulator as a periodic light source to excite the pixels of the camera's focal plane array. The image frames captured by the camera during excitation are then processed and the data fit using the algorithms developed to find the time constant for each pixel in the array.
