Abstract: A ranging system includes: a source generating a wideband incident wave that is transmitted toward a target and that is reflected by the target to form a reflected wave; a feedback detector to detect the reflected wave to generate a detected signal; an operator configured to perform low-pass filtering on the detected signal at an adjustable filtering bandwidth to generate a filtered signal, and calculate cross-correlation of a feedback signal that originates from the filtered signal and a reference signal that corresponds to the incident wave to generate a cross-correlation result; and a controller calculating a distance to the target based on an operation output that originates from the cross-correlation result.

Abstract: A multi-channel transmitter includes a light source, a pulse generator and a mode splitter. The light source generates a continuous source light wave with multiple modes that are different from each other in terms of wavelength and waveform. The pulse generator generates, based on the continuous source light wave, an intermediate light pulse with multiple modes that are different from each other in terms of wavelength and waveform. The mode splitter has a plurality of output terminals, and generates, based on the intermediate light pulse and respectively at the output terminals thereof, a plurality of output light pulses that respectively correspond to the modes of the intermediate light pulse.

Abstract: The present disclosure provides an image scanning system and an image scanning method. The image scanning method includes: receiving a first image of a first optical device and a second image of a second optical device; determining objects of the first image or the second image; selecting at least one of the objects of the first image or the second image as a region of interest to scan the region of interest continuously by the second optical device so as to obtain depth image information of the region of interest; and integrating the depth image information into the first or second image. Therefore, the present disclosure obtains higher image resolutions, faster scanning speeds and more accurate recognition results.
