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 the following elements. A force-applying element is adapted to apply a force to a target surface on a cornea of an eyeball in a direction, so that the target surface is deformed. A force-sensing element, coupled to the force-applying element, is adapted to sense the force applied by the force-applying element in the direction. A displacement-sensing element, coupled to the force-applying element, is adapted to sense a displacement of the force-applying element in the direction. A processing element is electrically connected to the force-sensing element and the displacement-sensing element to obtain a relationship curve between applied force and displacement. In particular, the processing element analyzes the relationship curve to obtain a characteristic critical point, and obtains an intraocular pressure value of the eyeball according to the applied force corresponding to the characteristic critical point.

Abstract: A photoacoustic detector, a photoacoustic board and a detector using the photoacoustic board are provided. The photoacoustic detector includes a X-ray transmitter, a X-ray receiver, a light module and an ultrasonic module. The X-ray transmitter is configured to transmit a X-ray to irradiate the object. The X-ray receiver is configured to receive an image beam generated after the object is irradiated by the X-ray. The light module is configured to provide light for illuminating the object to generate a first sonic wave signal. The sonic module is configured to receive the first sonic wave signal, transmit an sonic wave toward the object, and receive a second sonic wave signal generated after the object is interacted with the sonic wave. Therefore, a X-ray image, an ultrasonic image and a photoacoustic image are obtained via the photoacoustic detector.

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.
