Latest Patents

Dahong Qian holds a patent for a "Noncontact position measurement system using optical sensors." This invention combines optical and computational components to create a high precision, six degree-of-freedom, single-sided, noncontact position measurement system. The system utilizes reflective optical targets on a target object to sense its position. Light beams directed toward these optical targets produce reflected beams, generating electrical signals that indicate the points of intersection of the reflected beams and the position-sensitive detectors. The position-sensitive detectors may include lateral-effect photodiodes. The signals are transformed to provide measurements of translation along and rotation around three nonparallel axes, defining the space in which the target object moves. He has 1 patent to his name.
