Latest Patents

Yosef Akhtman holds a patent for a "Wide-angle computational imaging spectroscopy method and apparatus." This system is designed to provide a large field of view for capturing objects while maintaining a compact design. The system includes various imaging components and a computational device. The imaging components consist of a lens assembly, a fixed or variable-diameter aperture, a spectral filter array, and an imaging sensor. The lens assembly is engineered to offer a wide angle of view and image-side telecentricity, while also correcting for longitudinal chromatic aberrations. However, it may not correct for lateral chromatic aberrations. The lens assembly ensures that chief rays are incident perpendicular to the image sensor, producing different chromatic aberration patterns for each wavelength within the spectral range of interest. The pass-band nanofilter array filters specific bands of light reflected from the imaged object, generating multiple spatio-spectral samples projected onto the photosensitive pixels of the imaging sensor. The computational device reconstructs a complete spectral cube within the spectral range of interest, enabling the computation of object reflectance at each pixel of the captured image.
