Latest Patents

One of his latest patents is titled "Compact computational spectrometer using solid wedged low finesse etalon." This invention involves a two-layer hybrid solid wedged etalon combined with a traditional imager to create a compact computational spectrometer. The hybrid wedge, made of NbO and Infrasil 302, operates from 0.4-2.4 µm. Initial demonstrations utilized a CMOS imager and achieved spectral resolutions of <30 cm from single snapshots. The computational spectrometer functions similarly to a spatial Fourier Transform infrared (FTIR) spectrometer, employing a non-negative least squares fitting algorithm for spectral reconstruction. This innovative technique surpasses the performance and spectral resolutions achievable through traditional Fourier methods. Additionally, with extra imaging lenses and translational scanning, the system can be transformed into a hyperspectral imager.

Another significant patent is "Material property determination using photothermal speckle detection." This device includes a pump light source that irradiates a target specimen and a sensor that observes a probe speckle pattern based on light reflected from the specimen. A correlator analyzes changes in the probe speckle pattern images to determine the material properties of the target. This method offers higher sensitivity than existing techniques and allows for the use of visible probe wavelengths, making it accessible for low-cost visible detectors with high spatial resolution.
