摘要： A range image sensor comprising a light source, a light detecting element, a sensor control stage and an image construction stage. The image construction stage calculates a distance value for each image element in a range image based on each electric charge picked up after a specific detection period of different detection periods by the sensor control stage, and then constructs the range image. The specific detection period is one of one or more detection periods during which the light detecting element does not reach saturation, and is one detection period during which a value related to the quantity of light received from the object space becomes maximum of that of the one or more detection periods.

摘要： A preferably CMOS-implementable method and system measures distance and/or brightness by illuminating (22) a target (20) with emitted optical energy having a modulated periodic waveform whose high frequency component may be idealized as S1 = cos(a.t). A fraction of the emitted optical energy is reflected by a target and detected with at least one in a plurality of semiconductor photodetectors (240-N). Photodetector quantum efficiency is modulated (Fig. 8-10) to process detected signals to yield data proportional to the distance z separating the target and photodetector. Detection includes measuring phase change between the emitted optical energy and the reflected fraction thereof. Quantum efficiency can be modulated with fixed (Fig. 10) or variable (Fig. 9) phase methods and may be enhanced using enhanced photocharge collection, differential modulation, and spatial and temporal multiplexing. System power requirements may be reduced with inductors (Lp)that resonate with photodetector capacitance at the operating frequency. The system includes on-chip photodetectors, associated electronics, and processing.

摘要： The invention relates to a device for detecting the phase and amplitude of electromagnetic waves. The device comprises at least two modulation photo gates (1, 2) which are sensitive to the electromagnetic waves. The device also comprises accumulation gates (4, 5) which are assigned to said modulation photo gates and which are not photosensitive, and has electric connections for the modulation photo gates (1, 2) and for the accumulation gates (4, 5) such that the latter can be connected to a readout device and the previous can be connected to a modulating device. Said modulating device increases and decreases the potential of the modulation photo gates (1, 2) in relation to one another and in relation to the preferably constant potential of the accumulation gates (4, 5) corresponding to a desired modulation function. The invention provides that a plurality of modulation photo gates (1, 2) and accumulation gates (4, 5) are provided in the shape of long and narrow, parallel strips which form a PMD pixel in groups.
