Abstract

The concept has been demonstrated of using multiple sources to construct an imaging system to give range to each pixel in a wide field of view without a mechanical scanner. The receiver has a single detector that sees the entire field of view. With a diffuse reflector as a target, the system gave a range of 3 m with a range accuracy of 7.5 cm indoors when light-emitting diodes having an output of 5 mW were used as the sources. When laser diodes having an output of 15 mW were used, the maximum range outdoors in bright sunlight was 13 m with a range accuracy of 15 cm. When operation was outside but the target was shaded, the range accuracy was 7.5 cm.
