    5 Principle of Time of Flight Scope of remote sensing technology · Presence or proximity detection, where the absence or presence of an object in a general area is the only information that is required (e.g., for security applications). This is the simplest form of remote sensing; ·...
  • Page 16: Range-Gated Imaging Tof

    converted to a distance, based on the following equation: The difficulty in implementing the direct time-of-flight measurement method resides in the time intervals to be measured. In order to resolve a distance to centimeter-level accuracy, the required accuracy for the timers is 67 ps. Implemented in digital logic, this would require a 15 GHz clock speed, which is obviously not practical.
  • Page 17: Continuous Waveform Tof

    By measuring the energy received in successive integration intervals, it is possible to extrapolate the distance between the sensor and the measured object, based on the ratio of energy received in the different intervals. The difficulty with range-gated imaging is that CCD and CMOS imagers have a limited dynamic range;...
  • Page 18: Vzense Tof Principle

    5.1.4 Vzense ToF Principle Vzense DCAM500 product principle is based on range-gated imaging ToF solution, and the sensor inside is based on Panasonic CCD sensor MN34906.
  • Page 19: Noise Factors

    A strong ambient light may affect the accuracy and precision of the depth data, the Vzense DCAM500 is suggested to in user below 50K LUX ambient light. 5.2.2 Multipath Propagation Based on the principle of ToF, Multipath effect may happen when the light reflected more one once.
  • Page 20: Scattering Effect

    5.2.4 Scattering Effect Scattering light effect is a noise factor to ToF products, it is caused by multiple reflection inside the lens of camera or the cover of camera. To eliminate the scattering light effect, you should: 1. Keep the cover glass of the camera clean; 2.
