Claim Text:
1. A depth camera for a time of flight device for presenting three dimensional data to a host comprising: a light source for launching a beam of light at a range of interest for a field of view, the light source having an adjustable frequency and an adjustable peak optical power; a detector array for receiving and detecting portions of the beam of light reflected off of objects within the range of interest and field of view; and a controller for adjusting the light source frequency and peak optical power within a single frame time period in accordance with a plurality of frequency and peak optical power pairs to obtain a plurality of three dimensional data measurements for each frame time period, whereby the range of interest and field of view is divided into a plurality of volumes of interest, each volume of interest having a different, frequency, peak optical power, and minimum and maximum distance from the light source, to increase dynamic range and depth of field within each volume of interest.
