摘要
A motion sensor assembly is adapted to determine an angular velocity of a moving contrast in its field of view. The motion sensor assembly includes: a motion sensor with a first and a second analog photoreceptor each adapted for observing the moving contrast, the first and the second photoreceptors being separated by a predetermined interreceptor angle; and an angular velocity calculating unit connected to the first and second photoreceptors for calculating the angular velocity of the moving contrast based on a first and a second analog signal delivered by the first and the second photoreceptors, respectively. The first and the second analog signals delivered by the first and the second photoreceptors at are sampled a given sampling frequency to obtain a first and a second digital signal, respectively. An interpolator is configured to interpolate the first and the second digital signals upon their crossing a predetermined threshold between successive samples.
