摘要： The method serves for canceling errors caused by mismatch of different signal paths in a photodetector with a plurality (k) of storage elements for the photogenerated signals, as typically used in phase-measurement systems. The signal-capturing process is performed in at least two measurement cycles (j) . A first cycle (j=1) is executed with the conventional setup with no phase delay in the control signals. It is followed by further measurement cycles (j=2, 3, 4) which use control signals shifted by a constant phase shift (90°). Corresponding signals are read out through different signal paths. At the end, the signals corresponding to a certain phase (Φ) are added, thus canceling possible offset values.

摘要： Fluorescence lifetime imaging microscopy (FLIM) is a powerful technique increasingly used in the life sciences during the past decades. An all-solid-state fluorescence-lifetime-imaging microscope (1) with a simple lock-in imager (4) for fluorescence lifetime detection is described. The lock-in imager (4), originally developed for 3D vision, embeds all the functionalities required for FLIM in a compact system. Its combination with a light-emitting diode (2) yields a cost-effective and user-friendly FLIM unit for wide-field microscopes. The system is suitable for nanosecond lifetime measurements and achieves video-rate imaging capabilities.

摘要： The pixel (1) for use in an image sensor comprises a plurality of small-sized radiation-sensitive elements (2.1-2.9) for converting incident radiation into electric signals, the radiation-sensitive elements (2.1-2.9) being properly interconnected to form a larger radiation-sensitive area. The pixel (1) further comprises a plurality of storage elements (3A-3D) for storing the electric signals. The pixel further comprises transfer means for transferring the electric signals from the radiation-sensitive elements (2.1-2.9) to any selected one of the storage elements (3A-3D). The pixel (1) exhibits a high optical sensitivity and a high demodulation speed, and is especially suited for distance-measuring sensors based on the time-of-flight (TOF) principle or interferometry.

摘要： The modulation scheme disclosed in this invention report allows for utilizing multiple 3D time-of-flight cameras at the same time by exploiting the inherent pseudo noise properties of the optical modulation signals. Compared to recent systems based on pure pseudo noise modulation signals, the stochastic measurement error in a single-camera environment is significantly reduced. The basic concept relies on the generation of a three level optical modulation signal that includes two pseudo noise sequences.

摘要： A method to compensate for multi-path in time-of-flight (TOF) three dimensional (3D) cameras applies different modulation frequencies in order to calculate/estimate the error vector. Multi-path in 3D TOF cameras might be caused by one of the two following sources: stray light artifacts in the TOF camera systems and multiple reflections in the scene. The proposed method compensates for the errors caused by both sources by implementing multiple modulation frequencies.
