Abstract: A guiding fixation method applied to an eye examination device is disclosed. The eye examination device at least includes a first default light source and a second default light source. The guiding fixation method includes steps of: (a) disposing at least one dummy light source between the first default light source and the second default light source; (b) when a distance between the eye examination device and an eye changes, the dummy light source emitting light to guide the eye to gaze at it; (c) when the distance between the eye examination device and the eye stops changing, switching to the first default light source and/or the second default light source to emit light to guide the eye to gaze at it.

Abstract: A spectrometer is disclosed. The spectrometer includes a fiber input, a collimator lens, a rotating shaft, a grating, a focal lens and a focal plane which have arranged in order. A broadband incident light of the fiber input becomes a first parallel beam through the collimator lens and separated by the grating into multiple parallel beams of different wavelengths and then focused by the focal lens to emit an output beams to an imaging position on the focal plane. The spectrometer can rotate the collimator lens and fiber input to change the imaging position on the focal plane.

Abstract: An optical measuring device is provided. An actuator of a reference mirror set drives a reference mirror to move back and forth at a scan velocity. A first light source module transmits a first light beam to an optical coupling module transmitting two parts of the first light beam respectively to an examinee object and the reference mirror set. The first light beam then is reflected by the examinee object and reference mirror set and then transmitted to the optical coupling module and the processing unit. The second light source module transmits a second light beam to the examinee object. Then the second light beam is reflected and then transmitted to the second sensing unit. The second sensing unit provides a sensing signal to the processing unit which accordingly provides a value of the relative velocity. The thickness is calculated according to the relative velocity and the scan velocity.

Abstract: An endoscopy apparatus having high degree of motion freedom and the operating method thereof are disclosed. The endoscopy apparatus having high degree of motion freedom includes a multi-stage endoscopy module and a control module. The multi-stage endoscopy module includes at least a first endoscopy unit and a second endoscopy unit. The first endoscopy unit and the second endoscopy unit can provide a first bending and a second bending respectively. The second bending is larger than the first bending. When the multi-stage endoscopy module moves to a region near a target observing position, the control module will control the second endoscopy unit to generate slight deformation to observe a real-time state of the target observing position.
