Claim 9:
10. An imaging unit, comprising:
a light source that illuminates an object with a sequence of light pulses;
a time-resolving sensor that is synchronized with the light source and outputting a first signal and a second signal based on detecting one or more photons corresponding to a light pulse that have been reflected from a surface of the object, a first ratio of a magnitude of the first signal to a sum of the magnitude of the first signal and a magnitude of the second signal being proportional to a time of flight of the one or more detected photons, and a second ratio of the magnitude of the second signal to the sum of the magnitude of the first signal and the magnitude of the second signal being proportional to the time of flight of the one or more detected photons; and
a processor configured to determine a distance to the object based on the first signal and the second signal and to determine a surface reflectance of the object where the light pulse has been reflected based on the first signal and second signal.
