Optical fiber probe, optical detection device, and optical detection method |
摘要 |
An optical detection device image is disclosed that allows fast measurements using near-field light at high resolution and high efficiency but without necessity of position alignment of an optical fiber probe. The optical detection device includes an optical fiber probe having a core for propagating light with an optical probe being formed at a front end of the core; a movement control unit to move the optical fiber probe to approach or depart from a sample; and a detection unit to detect light from the sample surface, wherein on the front end surface of the core of the optical probe, there are a first exit section on a peripheral side for emitting propagating light and a second exit section for seeping out the near-field light, the first exit section and the second exit section are formed in a concentric manner, and the tilt angle of the first exit section is different from the tilt angle of the second exit section.
