Figure 1 shows a diagram using two 1x3 optical branching couplers.
A configuration diagram of a transmission-type multi-point object detection sensor in which three light-emitting elements and three optical fibers for emission, one light-receiving element and three optical fibers for input are connected. This is a reflective multi-point position sensor that connects one light emitting element and two emitting optical fibers using an optical branching coupler, and consists of two light receiving elements.
Figure 3 shows the configuration of a reflective multi-point temperature sensor in which one light-emitting element, one light-receiving element, and two sensor sections are connected by optical fiber using a 2x2 optical branching coupler. It is a diagram. DESCRIPTION OF SYMBOLS 1... Light emitting element, 2... Optical fiber for light emitting side connection, 3... Light emitting side optical branching coupler, 4... Object, 5
