IMAGING RANGE FINDING DEVICE AND METHOD

Imaging range finding device and method are disclosed. The range finding device can include an array of emitters and photodetectors in optical communication with an imaging lens. During the range finding method, the emitters in the array can emit light that is directed by the lens toward a target object. The photodetectors in the array can detect light received from the object through the lens and onto the photodetectors. The lens, the array, or both can be movable to adjust the light emitted by the device. Characteristics of the emitted light and/or the received light can be used to find the object's range.
