Optical sensor device










Image Number 14 for United States Patent #8125620.

A method and apparatus for the acquisition of repetitive signals in a sensing device comprising a transmitter, a receiver and an object. The transmitter repetitively emits a modulated electro-magnetic signal into a transmission medium, with the emitted signal interacting with the object producing a counter propagating return signal. The return signal may contain properties that reflect all, or a portion, of the initial signal or may be correlated with said signal through a process of absorption and reemission, in which reflected signal characteristics are governed by the object's physical material characteristic. The return signal is detected and converted into digital signals by a receiver via a reception channel through the use of edge transitions rather than logic levels from one or more comparator outputs to reconstruct the return signal waveform. A several waveform acquisition and reconstruction methods are disclosed for use with an edge sampling detection apparatus. When directed towards the time-of-flight distance measurement the invention also discloses a useful method to provide optical feedback using a moving waveguide.
