Optical fiber fabric and optic nerve activity measurement support device

摘要

An object of the present invention is to form a light emitting portion that emits planar light with a light transmitting portion by setting the weft density of an optical fiber fabric to an appropriate range, and efficiently emits leaked light by bending the optical fiber in the light emitting portion. Provided are an optical fiber fabric and an optic nerve activity measurement support device which have no problems with the nature. The optical fiber fabric 1 has an optical fiber as a warp 3 and a yarn including an elastic yarn as wefts 4a and 4b, and transmits a light from a light source 2 to a light emitting portion 6; The bending angle at which the optical fiber of the warp crosses with the weft is smaller in the light emitting part 7 than in the light transmitting part 6, and the light emitting part 7 leaks the light 5a-5e due to the bending of the optical fiber. It emits light. The optic nerve activity measurement support apparatus of the present invention is connected to the optical fiber fabric for irradiating the eye with stimulating light.
