Latest Patents
Di Cecca holds a patent for a "Compact computational spectrometer using solid wedged low finesse etalon." This invention features a two-layer hybrid solid wedged etalon that is combined with a traditional imager to create a compact computational spectrometer. The hybrid wedge is constructed from NbO and Infrasil 302, designed to operate within the wavelength range of 0.4-2.4 µm. Initial demonstrations utilized a CMOS imager, achieving operation from 0.4-0.9 µm with spectral resolutions of less than 30 cm from single snapshots. The computational spectrometer functions similarly to a spatial Fourier Transform infrared (FTIR) spectrometer, employing spectral reconstruction through a non-negative least squares fitting algorithm. This algorithm is based on analytically computed wavelength response vectors derived from the physical thicknesses across the two-dimensional wedge. The computational technique employed results in performance and spectral resolutions that surpass those achievable through traditional Fourier techniques. Additionally, with the incorporation of extra imaging lenses and translational scanning, the system can be transformed into a hyperspectral imager.
