Abstract

The present disclosure relates to an optical tracking device and a method of operation thereof, comprising emitting light towards a surface by a light source at regular first intervals of a first frequency with a first predetermined duration; receiving light reflected from the surface by an image sensor; determining image arrays from the light received by the image sensor at the regular first intervals, the image arrays comprising a first plurality of pixels; generating a first comparison array between the first image arrays generated at subsequent first intervals; determining a first displacement amount based on the first comparison array; wherein, if the first displacement amount is bigger than a displacement amount threshold, the method further comprises: emitting light towards the surface at regular second intervals of a second frequency with a second predetermined duration, determining second image arrays from the light received by the image sensor at the regular second intervals, the second image arrays comprising a plurality of pixels, generating a second comparison array between the second image arrays generated at subsequent second intervals, determining a second displacement amount based on the second comparison array.
