  • Patent number: 10996104
    Abstract: Apparatus and associated methods relate to creating corrected images of a scene for a terminal-imaging seeker using an electrically-controllable coded-aperture mask pattern embodied in a programmable spatial light modulator. The coded-aperture mask pattern includes a plurality of pinhole-like apertures, each of which is configured to perform pinhole-like lensing of the scene. The plurality of pinhole-like apertures form a multiplex of overlapping images on a focal plane array aligned with the optical axis. An image processor reconstructs, based on a configuration of the plurality of pinhole-like apertures and the multiplex of overlapping images, a single image of the scene.

  • Patent number: 10989584
    Abstract: The disclosure relates to a method for measuring fill level of a fill substance using terahertz (THz) pulses or for determining distance to an object using terahertz pulses, as well as to a fill-level measuring device suitable for performing such method. The THz pulses are transmitted with a repetition frequency, wherein the repetition frequency according to the invention is controlled in such a manner as a function of travel time that the repetition frequency increases in the case of decreasing travel time and decreases in the case of increasing travel time. The separation or the fill level is determined not based on the measured travel time, but is based on repetition frequency. An exact fill level determination can be performed based on THz pulses, even when the frequency of the THz pulses significantly fluctuates. Consequently, very simply embodied pulse production units with comparatively small requirements for frequency stability of the THz pulses can be used.
