Abstract: An image sensor includes a pixel array across a substrate, with at least one pixel of the array being defined by dielectric walls extending from both the top and bottom surfaces of the substrate. The dielectric walls contact each other within the substrate. The dielectric walls encircle around, or form a perimeter around, a volume of semiconductor material that defines the pixel. In this way, light entering through one end of the pixel is generally confined between the dielectric walls as it traverses through the height of the pixel. By using two different dielectric walls formed from the frontside and backside of the substrate, thicker substrates can be used which increases the quantum efficiency of the pixel.

A spectrometer includes a slit formed at the first image plane to allow a slit-shaped portion of the light pass through.

A focusing lens focuses the spectrally dispersed light at a second image plane such that the spectral dispersion is imaged along a first axis thereof, and a spatial image of the slit width is imaged along a second axis for detection by a sensor. A sliding lens group between the optical channel and the first image plane moves to direct the incident light, scanning the entire image over the slit such that multiple frames acquired by the sensor each correspond to a horizontal line of the image.

Abstract: An imaging spectrometer and camera are disclosed including a prism that refracts incident light a spectral range for spectrographic analysis with a shortest wavelength (?S) and a longest wavelength (?L). A diffraction grating is aligned with the prism and diffracts the incident light. The refraction and diffraction for a set of diffraction orders used for the spectrographic analysis both increase a deflection angle of the incident light from an original optical axis. The spectral range spans greater than an octave such that ?L>2?S. The refraction and diffraction are such that a second diffracted order of ?S does not overlap with a first diffracted order of wavelengths shorter than ?L. The second order diffraction for wavelengths between ?S and ?C, and the first order diffraction for wavelengths between ?C and ?L, are detected in different spatial regions to perform the spectrographic analysis from ?S to ?L.
