    摘要: A time of flight (TOF) based camera system includes an illumination module that illuminates only portion of the sensor's field of view that translates to a given region of the pixels of the imaging sensor. The acquired data of the pixel region is processed and/or readout, typically. After the exposure time of the first pixel region is completed, a second pixel region is illuminated and the second pixel region is processed. This procedure can be repeated a couple of times up to a few hundred even thousand times until the entire pixel array is readout and possibly read-out a number of times. The full depth image is then reconstructed based on the results from the different pixel region acquisitions. This system can be used to reduce stray light. Compared to state-of-the-art TOF camera, the presented method and device show improvements in background light stability and a reduction in multiple reflections.

    摘要: A pixel based on a pinned-photodiode structure that creates a lateral electric drift field. The combination of the photodiode with adjacent CCD gates enables the utilization of the drift field device in applications such as 3-D imaging. Compared with recently used demodulation devices in CCD or CMOS technology, the new pinned-photodiode based drift field pixel has its advantages in its wide independence of the quantum efficiency on the optical wavelength, its high optical sensitivity, the opportunity of easily creating arbitrary potential distributions in the semiconductor, the straight-forward routing capabilities and the generation of perfectly linear potential distributions in the semiconductor.

    摘要: A method for filtering distance information from a 3D-measurement camera system comprises comparing amplitude and/or distance information for pixels to adjacent pixels and averaging distance information for the pixels with the adjacent pixels when amplitude and/or distance information for the pixels is within a range of the amplitudes and/or distances for the adjacent pixels. In addition to that the range of distances may or may not be defined as a function depending on the amplitudes.

    摘要: The sensitivity of a reference pixel array RPA to the reference modulated light MLR is varied for different reference pixels RP of the reference pixel array RPA. In one embodiment the different sensitivities of the reference pixels RP in the RPA is achieved by designing the pixels to have different light sensitivities with respect to each other. In another embodiment, the different sensitivities are achieved by changing optical coupling between the separate reference pixels RP of the reference pixel array RPA to the reference modulated light MLR such as by changing how the different reference pixels RP couple to the aperture LGA of the light guide LG.

    摘要: A two-dimensional, temporally modulated electromagnetic wavefield, preferably in the ultraviolet, visible or infrared spectral range, can be locally detected and demodulated with one or more sensing elements. Each sensing element consists of a resistive, transparent electrode (E) on top of an insulated layer (O) that is produced over a semiconducting substrate whose surface is electrically kept in depletion. The electrode (E) is connected with two or more contacts (Cl; C2) to a number of clock voltages that are operated synchronously with the frequency of the modulated wavefield. In the electrode and in the semiconducting substrate lateral electric fields are created that separate and transport photogenerated charge pairs in the semiconductor to respective diffusions (Dl; D2) close to the contacts (Cl; C2). By repetitively storing and accumulating photocharges in the diffusions (Dl; D2), electrical signals are generated that are subsequently read out for the determination of local phase shift, amplitude and offset of the modulated wavefield.

    摘要: The present invention discloses an optoelectronic detector for light sensing. The optoelectronic detector has a photosensitive element that converts light into electrons. Efficient collection of these electrons at readout nodes, embedded in the photosensitive element, is required to make correct measurements of light characteristics such as, phase shift and intensity. This collection of electrons is achieved by applying a voltage gradient across an electrode within the optoelectronic detector. The optoelectronic detector can have multiple readout nodes. Further, the present invention discloses methods for detecting intensity and phase shift of impinging light and for suppression of background illumination while detecting the characteristics of light.
