    Abstract: The present invention relates to a photonic mixer device with a photosensitive layer, at least two modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) and at least two readout electrodes (1, 2, 101, 102, 201, 202, 301, 302, 401, 402, 501, 502, 601, 602) connected to the photosensitive layer, the modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) being able to be connected to a modulation device which raises and lowers the potential of the modulation gates relative to one another and relative to the preferably constant potential of the readout electrodes corresponding to a desired modulation function. In order to further develop the known photonic mixer device such that it shows an increased charge conversion efficiency and reduced dark currents, it is proposed according to the invention that the readout electrodes (1, 2, 101, 102, 201, 202, 301, 302, 401, 402, 501, 502, 601, 602) in each case have at least two discrete electrode sections (1A-1E, 2A-2E) arranged at a distance alongside each other.

    Abstract: A spectral feature of a pulsed light beam produced by an optical source is estimated by modifying the wavelength of the pulsed light beam based on a predefined repeating pattern having a pattern period including a plurality of steps, the modification including shifting the wavelength of the pulsed light beam by a wavelength offset from a baseline wavelength for each step in the pattern period; measuring the wavelength of the light beam for each step in the pattern period as the wavelength is modified across the pattern; and estimating a spectral feature of the pulsed light beam over an evaluation window that includes all of the steps within the pattern period based at least in part on the measured wavelength of the light beam for each step in the pattern period.

    Abstract: The presented invention concerns an apparatus for detecting the phase and amplitude of electromagnetic waves, comprising at least two modulations photogates which are sensitive to the electromagnetic waves, and accumulating gates which are associated with the modulation photogates and which are not photosensitive, and electrical connections for the modulation photogates and the accumulation gates so that the latter can be connected to a reading-out device and the former can be connected to a modulating device which increases and reduces the potential of the modulation photogates relative to each other and relative to the preferably constant potential of the accumulation gates corresponding to a desired modulation function. It is proposed in accordance with the invention that a plurality of modulation photogates and accumulation gates are provided in the form of long narrow parallel strips which group-wise form a PMD-pixel.
