Disclosed are an optical fiber probe and a method for manufacturing an optical fiber probe which can reduce astigmatism. The disclosed optical fiber probe comprises:

Optical fiber probe and method for manufacturing optical fiber probe

Disclosed is an annular-beam coupling system enabling reduction of noise generated from a core of a double-clad fiber. The disclosed annular-beam coupling system comprises: a fiber for transmitting light of a light source; a collimator for receiving the light outputted from the fiber and forming a parallel beam of a circular shape; an annular-beam generation unit for converting the parallel beam into an annular beam; and a double-clad fiber having the annular beam coupled to a cladding region thereof.

Annular-beam coupling system

An optical probe, according to one embodiment, comprises: an optical fiber into which light for irradiating an object is incident from a light source; a lens which focuses the light incident into the optical fiber; and a wavefront modulator on which a pattern is formed so that the wavefront of the light incident into the optical fiber can be modulated, wherein the optical fiber, the lens, and the wavefront modulator are arranged on the same axis, the light passing through the wavefront modulator can form a focus on the same axis, and the resolution or focal depth of the light can be adjusted through a pattern design formed on the wavefront modulator.
