    摘要： An electronic device includes a ranging light source and a reflected light detector. A logic circuit causes the ranging light source to emit ranging light at a target. Reflected light from the target is detected using the reflected light detector, with the reflected light being a portion of the ranging light that reflects from the target back toward the reflected light detector. An intensity of the reflected light is determined using the reflected light detector. A distance to the target is determined based upon time elapsed between activating the ranging light source and detecting the reflected ranging light. Reflectance of the target is calculated, based upon the intensity of the reflected light and the distance to the target.
