Abstract: An optical detection system integrating tonometer and autorefractor includes first and second optical modules. The first optical module includes a light source, first and second lens sets, a reflector, a first light-splitter and a sensor. The first lens set and reflector are disposed corresponding to light source. The first light-splitter is disposed corresponding to the reflector, second lens set and sensor. The second optical module includes a second light-splitter and first to third optical elements. The incident light emitted by the light source passes through the first lens, reflected by the reflector, passes through the first light-splitter, reflected by the second light-splitter, passes through the first to third optical elements and emitted to an eye. A sensing light from the eye passes through the third to first optical elements, reflected by the second light-splitter and first light-splitter, passes through the second lens set and emitted to the sensor.

Abstract: An optical intraocular pressure measuring apparatus includes a light source, an optical module, a pressure providing module, a deformation measuring module, and a processing module. The light source provides an incident light. The optical module divides the incident light into a first incident light and a second incident light and emits them to a reference object and an object to be detected through a first light path and a second light path, and receives a first reflected light signal from reference object and a second reflected light signal from the object to be detected respectively. The pressure providing module coupled with second light path provides a pressure to deform the object to be detected. The deformation measuring module measures the deformation of the object to be detected. The processing module processes the first reflected light signal and second reflected light signal to generate an intraocular pressure measurement result.

Abstract: An optical measuring apparatus includes a first light source, a second light source and a switching unit. The first light source is used to emit a first light toward a first direction. The second light source is used to emit a second light toward a second direction. The switching unit selectively switches to a first mode or a second mode. When the switching unit switches to the first mode, it blocks the second light and let the first light emitted to an aiming region on eyeball to perform an optical aiming and determine an eye axis center position on the eyeball; when the switching unit switches to the second mode, the switching unit changes the second light from the second direction to the first direction to let the second light emitted to the eye axis center position on the eyeball to perform an optical measurement.

Abstract: An auxiliary staring and imaging focusing device includes an illumination system, an imaging system, a staring device and a focusing device. The illumination system has an illumination optical-path to project a detection light to illuminate a fundus of a subject's eye. The imaging system has an imaging optical-path for receiving a reflected light and a fundus image of subject and imaging the reflected light and fundus image on an image display. The staring device is located in the illumination optical-path and forms a staring surface provided with staring points contrast with a detection light for the subject to watch. The focusing device is provided with a split-image screen in the illumination optical-path. The split-image screen has a shutter with a default size, and two facing prisms are disposed on the shutter and a light-transmitting space is formed between two prisms for a center staring point to pass through.
