TRANSMISSION RECEPTION EQUIPMENT FOR VARIOUS QUANTITIES OF ROTATING BODY

PURPOSE:To use a multichannel light emitting body to accurately measure various quantities of a rotating body, to extend the measurement range, and to extend the application range of measurement in accordance with the structure of an object to be measured. CONSTITUTION:This equipment is provided with a rotation-side rotating body various quantities converter 3 provided in a rotating body 1, a rotation-side signal processing unit 4 which is connected to the converter 3 and converts an inputted-electric signal to a digital signal to output it, a rotation-side optical element unit 5 which is connected to the signal processing unit 4 and is provided with first optical element groups 20A to 27A which convert the digital signal to optical signals S3 to S5 and S12 to S16 to transmit them, a fixed-side optical element unit 6 which receives optical signals S3 to S5 and S12 to S16 transmitted from first optical element groups 20A to 27A to output an electric signal, and a fixed-side signal processing unit 7 which is connected to the optical element unit 6 and measures various quantities of the rotating body by numerical processing of the inputted electric signal.
