Abstract
Visidyne proposes to demonstrate innovative technologies to locate points on a human body with sub-mm precision and a low latency. Small (potentially << 1 cm3), battery-powered laser transmitter tags are attached to the subject at various points-of-interest (head, elbow, wrist, knee, etc.). Pulses from the tags are detected by a fixed constellation of receivers at known locations. The receiver signals are then processed using proprietary Visidyne phase measurement technology to solve for the position in 3-D space of each tag. Conceptually the design resembles the Global Positioning System (GPS) in that it uses trilateration to determine locations within a given volume. As with GPS, the design is highly scaleable with the low incremental cost per measured point. The proposed technology builds on previous activities at Visidyne for tracking the orientation of a helmet in an aircraft cockpit for cueing of sensors and weapons.
