Abstract: An OCT scanning probe includes a tubular housing, at least one electrode, an optical fiber scanner and an auxiliary localization component. The electrode is disposed on an outer surface of the tubular housing. The optical fiber scanner is disposed in the tubular housing and includes an optical fiber and an optical element. The optical element is disposed on an emitting end of the optical fiber and at corresponding position to a light transmittable portion of the tubular housing. The auxiliary localization component is disposed on the tubular housing, and overlaps part of the light transmittable portion. A light beam emitted from the optical fiber scanner passes through the light transmittable portion to obtain a tomographic image. An interaction of the light beam with the auxiliary localization component causes a characteristic in the tomographic image, with the characteristic corresponding to the auxiliary localization component.

Abstract: An optical system adapted to detect an object including a beam splitting and combing element, a catheter, a focusing element, a deformation detecting module, and an object detecting module is provided. The catheter sleeves outside an optical fiber, and the optical fiber has at least one fiber Bragg gratings. The deformation detecting module and the object detecting module are coupled to the beam splitting and combing element. A first light is reflected by the at least one fiber Bragg gratings and then transmitted to the deformation detecting module. A second light is transmitted to and reflected by the object, so as to be transmitted to the object detecting module. A first wavelength range of the first light is different from a second wavelength range of the second light.

Abstract: An intraocular pressure detecting device includes a pressure generation unit, a light source, an image sensing unit and a processing unit. The pressure generation unit applies pressure to a target surface of an eyeball along a first operation axis direction, such that a deformation is generated on the target surface. The light source emits light that irradiates the target surface along a second operation axis direction, so as to generate a speckle pattern on the target surface. The image sensing unit observes and records an image variation of the speckle pattern along a third operation axis direction. The processing unit is signally connected with the image sensing unit to receive an image of the speckle pattern. The processing unit identifies and analyzes a feature size of the image of the speckle pattern for obtaining an intraocular pressure value of the eyeball. An intraocular pressure detecting method is also described.
