  • Patent number: 5446529
    Abstract: A three dimensional imaging device and method is presented which uses a pulsed light source for detecting objects enveloped by a light-transmitting and light-reflecting and scattering medium such as water or biological tissues. By means of high-speed switching between many storage capacitors the third dimension is recorded by the device with a single pulse from the light-source. The device consists of the pulsed light source, optics for collecting the reflected and scattered light, one or more sensors for detecting the light, drive and output electronics for timing and signal conditioning of data generated by the sensors and processing electronics and software for converting the sensor data to a three dimensional image. The sensors use known technologies for light amplification but collect and process the light-amplified data in a unique manner, using an analog-processing readout chip.

  • Patent number: 6133989
    Abstract: A three dimensional imaging device is presented which uses single pulse from a pulsed light source for detecting objects enveloped by a light-transmitting medium such as the earth's atmosphere or free space. By means of switching off a ramping voltage, individually for each object pixel, the time of arrival of the reflected pulse is recorded. This time is related to the third object dimension. The device consists of the pulsed light source, optics for collecting the reflected light, a sensor for detecting the light, drive and output electronics for timing and signal conditioning of data generated by the sensors and a computer for processing the sensor data and converting it to a three dimensional image. The sensor collects and processes the light data in a unique manner, using a hybrid. The hybrid is actually a two dimensional array of collectors or detectors combined in very close proximity with their own processing electronics.
