Abstract
In the sending and receiving of a signal through an optical waveguide, an unknown substrate connected to the optical waveguide can be recognized. A signal processing apparatusA is provided with an optical waveguideA in which the light input from an arbitrary position on an outer circumference is output in an entire circumference direction at a level in accordance with a positional relation with the input location, a master substrateM arranged on the outer circumference of the optical waveguideA, a single or a plurality of slave substratesS arranged at any of a plurality of mount locations at different positions along the outer circumference of the optical waveguideA, in which as the light is output from A laser diodesS of all the slave substratesS connected to the optical waveguideA, from a level of a light transmitted through the optical waveguideA and input to the photo detectorM of the master substrateM in accordance with the arrangement of the slave substrateS, the master substrateM recognizes the mount positions and number of the slave substratesS.
