  • Patent number: 11681024
    Abstract: An imaging device is described which, in some examples, includes general pixels and phase difference pixels. The general pixels, when operated by control signals, receive light from a subject and generate currents or voltages that are measured; a depth is estimated based on the measurements. The phase difference pixels generate currents based on a switched charge source. Data obtained from the currents generated by the phase difference pixels is used to adjust the control signals and thereby improve an accuracy of the depth estimation.

  • Patent number: 11656140
    Abstract: An active apparatus includes a pressure sensor array. The pressure sensor array includes at least one transducer and a standard optical fiber mechanically coupled thereto. The active apparatus includes a distributed Bragg reflector fiber laser located within the optical fiber. The fiber laser emits a wavelength. The fiber laser consists of two fiber Bragg gratings, which define a linear cavity. The linear cavity is mechanically coupled to the at least one transducer. A pressure change detected by the at least one transducer causes at least one property change in the optical fiber. For example, the at least one property change in the optical fiber causes a change in the cavity length. The change in the cavity length causes a wavelength shift relative to the wavelength emitted by the fiber laser.
