Abstract

A time of flight sensor has an image region and a storage region on a device which may be a CCD. A pulse of light illuminates an object, and an image illumination stripe is recorded on the image region. In a distance determining step, the image region is clocked after emitting the pulse of light and the row in which the image illumination stripe is illuminated gives a measure of the distance to the object. The apparatus can self calibrated by emitting a pulse of light without clocking the image region.
