Abstract: The present application discloses a sensing signal receiving system and method. The system includes an interface module configured to receive a sensing signal, a narrowband frequency-selective module configured to determine a frequency-selective signal in the sensing signal according to a preset receive frequency, a high amplification module configured to amplify the received frequency-selective signal to obtain an amplified signal, and an in-phase comparison module configured to convert the amplified signal into a TTL standard signal. A frequency of the frequency-selective signal is the preset receive frequency or is a narrowband section including the preset receive frequency. The narrowband frequency-selective module is further configured to output the frequency-selective signal to the high amplification module.

Abstract: A measurement system is described herein that accurately calculates the complete position and orientation of a dynamic object in real-time. The measurement system includes a laser unit, a target, a camera unit, and a control unit. The target is arranged to rotate about all three spatial axes, and includes a reflective element, a gyroscope, and a pair of light emitting devices. The laser unit is arranged to rotate about two of its spatial axes, and further arranged to emit a laser beam toward the target. The reflective element reflects the laser beam back toward the laser unit, where the laser unit detects the returned laser beam. The camera unit is arranged to detect light emitted from the pair of light emitting devices. The control unit is arranged to gather information and data captured by the system to determine the position and orientation of the object.

Abstract: An automatic target tracking system and method employ an image capturing system for acquiring a series of images in real time of a distant area containing a remote target, and a processing system for processing the acquired images to identify the target and follow its position across the series of images. An automatic beam steering and method operate in conjunction with a laser source for emitting a laser beam to be transmitted in the form of a transmitted laser beam extending along a steerable beam transmission axis to the remote target. The beam steering system is controlled by the processing system to steer the beam transmission axis to be aimed at the target being tracked by the target tracking system, so that the transmitted laser beam will be transmitted at the appropriate angle and in the appropriate direction to be aimed at the tracked target.
