An optical fiber for an optical fiber sensor and a chemical sensor using the same are disclosed. The optical fiber includes a core area, and a suspended cladding area formed around the core area and having at least one cladding hole. The core area has at least one core hole for reducing an effective refractive index of the core area. The optical fiber and the chemical sensor using the same may have improved measurement sensitivity by increasing an evanescent field fraction of existing suspended core fibers.

Optical fiber for chemical sensor

A holographic characterization and playback apparatus is provided, which includes a light source, an optical path-forming optical system for separating the light emitted from the light source into a probe light and a reference light of different polarizations, and combining optical paths of the probe light and the reference light.

Holographic characterization and playback apparatus

The present invention relates to an optical coherence tomography device and an optical coherence tomography method using same for capturing the cornea and the retina of the eye by using light sources in respectively different wavelength ranges. According to the present invention, included are two light sources, a first interferometer and a second interferometer for generating respectively different interference patterns by the light outputted from each of the light sources, and interference pattern detection means for detecting an interference pattern occurring in each interferometer.
