Abstract
A technique for relative velocity determination between a surface and a velocity determination system involves capturing a set of outputs from a first photosensor array and then comparing subsequently captured sets of outputs from a second photosensor array to the set of outputs from the first photosensor array until a satisfactory match is found between the outputs. Once a satisfactory match is found, the elapsed time between the capture of the two sets of outputs represents the time to travel the known separation distance between the two photosensor arrays. Given the known distance of travel and the elapsed time to travel the distance, the relative velocity is a simple calculation of the distance traveled divided by the time to travel the distance.
