OPTICAL CONTROL SENSOR SYSTEM

摘要

A optical control sensor system includes a driver (102) controlling operation of a light source (103) coupled to an end of an optical fiber (105), an orthogonal signal generator (101), generating a set of different orthogonal signals controlling the driver, a terminal sensor (104) coupled to another end of the optical fiber selecting a predetermined set of input orthogonal signals for converting them into component combinations, constituting output signals, and directing the output signals back to the optical fiber, a device (108) coupled to the light sources and to the first end of the optical fiber for extracting output signals that have passed through a return path in the optical fiber, a detector (109) converting optical output signals into electrical signals, and a selector (110) and a decoder (111) connected to the orthogonal signal generator indicating a current state of the optical control sensor system.
