|
Expert has designed and modeled the performance of complete thermal imaging systems, remote temperature monitoring systems, infrared absorption systems, remote temperature monitoring systems, and other types of sensing systems. He has modeled the performance of each component of these systems and combined all of the components to generate a detailed performance model of the complete system.

Expert has worked in the electro-optics field since 1979. He has developed electron-bombarded CCD imagers for very faint visible light. The substantial portion of Expert's effort has been directed toward the development of infrared detectors and hybrid focal plane arrays and infrared imaging systems. He has studied device physics such as the interaction of electromagnetic radiation with the electrons in the detector and the effects of material defects such as dislocations and surface passivation. Expert has substantial wafer processing experience. He has designed infrared detectors and arrays and has helped others design the silicon readout integrated circuits (or multiplexers) to which infrared detector arrays are hybridized. He has developed interconnect processes for hybridizing infrared focal plane array procedures, including indium bump bonding and wire bonding techniques. He has designed, built, and used extensive test and characterization facilities for detectors and imaging arrays. In addition to CCDs, Expert has worked with long wave, medium wave, and short wave infrared (LWIR, MWIR, and SWIR) HgCdTe, InSb, PbSe, and PbS detectors and arrays and the uncooled silicon microbolometer.

Expert has designed complete sensors to detect infrared radiation. This has included the detector, packaging including the Dewar and cooling system, optics, and electronics. He has also set up test facilities to calibrate the sensor. For the past 20 years, Expert has worked on developing infrared detectors and detection systems sensitive to 3-5 micrometer radiation. He has developed HgCdTe, InSb, and PbSe detectors. He has designed thermal imaging systems using large arrays of these detectors. He has also designed numerous detection systems using single-element detectors and small arrays using these detectors and several others. Expert has designed a sensor that detects a hydrocarbon flame by sensing both the infrared and ultraviolet signatures of the flame over narrow spectral regions. By simultaneously detecting both IR and UV, he found that the false alarm rate to be greatly reduced.

Expert has developed complete imaging systems, including the focal plane array, Dewar, cooling system, optics, electronics, and the system interfaces. He has designed drive electronics that operate FPAs and analog and digital signal processing electronics that extract the images from the background. He has worked extensively with cryogenically-cooled systems using Stirling cycle engines and Joule-Thompson cryostats as well as thermoelectrically cooled and uncooled systems. Expert has set up test facilities to fully characterize infrared imaging systems and has also set up computer models that accurately predict the performance of complete imaging systems. Expert has originated several infrared thermometers designed to remotely measure the surface temperature of objects. The application of these devices include a temperature "gun" used to measure the surfaces of industrial facilities and a controller for an induction furnace.

|
Over the course of his career, Expert led teams that developed both low-cost and high-performance infrared line scanners. Examples are a low-cost line scanner that used a thermoelectrically cooled linear PbSe FPA and operated in the MWIR band and a SWIR/MWIR multispectral high-performance line scanner that used two dimensional InSb arrays operated in the time-delay-and integrate mode and was designed for very low light levels.
|
|
|
Expert has written a set of computer programs that calculate the electromagnetic radiation emitted by a source and the radiation incident on a detector. The amount of energy and the number of photons in any spectral band can be calculated. These calculations are used extensively in designing infrared sensors and imaging systems.
|
|
|
Having used InSb photodiodes for detection of mid-wave infrared (MWIR) radiation for many years, Expert has designed MWIR imaging systems using very large InSb arrays that detect very low radiation levels with background limited performance.
|
|
|
Expert has designed several infrared cameras sing InSb and HgCdTe photodiodes and PbS photoconductive detectors. The InSb and PbS cameras detected radiation in the mid-wave infrared (MWIR) 3-5 micrometer wavelength radiation region. The HgCdTe cameras detected radiation in the long wave infrared (LWIR) 8-12 micrometer wavelength region. The systems were staring and scanning. The HgCdTe and InSb scanning systems also had time-delayed-and-integrate (TDI).
|
|
|
In an area of secondary expertise, Expert designed, fabricated, and characterized charge-coupled devices (CCDs) during the development of virtual phase (uniphase) CCD at Texas Instruments. He developed a frontside-illuminated, electron-bombarded CCD that detected individual photons with a signal-to-noise ratio of 10.
|
|
|
Expert transferred manufacturing of a laser modulator from development to production. He developed computerized assembly techniques for a laser modulator that significantly reduced cost and increased reliability.
|
|
|
Expert has designed gas detection sensors using the absorption of infrared radiation. These sensors determine the concentration of a specific gas by measuring the amount of radiation absorbed at specific wavelengths; those wavelengths corresponding to electronic transitions in the molecules being detected. He has used several types of detectors for these sensors, depending on the cost and performance requirements.
