摘要： The present invention relates to a method for measuring a time delay between two output signals measured by two adjacent optical sensors, the time delay resulting from a movement of an object moving in a given direction. The method comprises the steps:
- carrying out a spatial filtering of the signals Ph 1 and Ph 2 delivered by a first and a second optical sensor;
- calculating a first order derivative and carrying out a temporal low-pass filtering of the signals;
- calculating the second order derivative of the signals;
- measuring the delay between the signals;
and is characterized in that the step of measuring the delay is a feedback loop based on an estimated delay between the temporally filtered signals.

摘要： The present invention relates to a method for measuring the angular position of a contrasting edge of an object having a luminance transition zone which is substantially rectilinear in a given direction and separates two regions of different luminances. This method comprises the functional steps of:
- carrying out, in a transverse direction different from the given direction, an amplitude modulation of the signals delivered by a first and a second optical sensor; and
- calculating an output signal (Y out (t)) starting from the signals delivered by the first and the second optical sensors (D 1 , D 2 ) as a function of the angular position of the luminance transition zone.
