Optical fiber probe, light detection device, and light detection method |
摘要 |
An optical fiber probe is disclosed that comprises an optical fiber and an optical probe. The optical fiber includes a core though which light emitted from a light source travels. The optical probe is configured to emit the light from a projecting end portion of the core. An inclination angle of a normal line of a part or all of a surface of the optical probe with respect to an optical axis of propagating light that travels through the core is smaller than a total reflection angle of the propagation light but greater than zero degrees.
