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 biometer includes a light-source module, a light-splitting module, a reference-arm, a sensing-arm and a sensing module. The light-source module emits incident-light. The light-splitting module, disposed corresponding to light-source module, divides the incident-light into reference light and sensing light. The reference-arm, disposed corresponding to light-splitting module, generates a first reflected-light according to the reference light. The sensing-arm, disposed corresponding to the light-splitting module, emits the sensing light to the eye and receives a second reflected-light from the eye. The sensing module generates a sensing result according to the first reflected-light and second reflected-light. In a first mode, the sensing light is emitted to a first position of the eye. In a second mode, the sensing light is emitted to a second position of the eye. The incident-light emitted by light-source module is partial annular light and the sensing result includes a partial annular image related to the eye.

Abstract: An optical system applied to an optical biometer is disclosed. The optical system includes a light source, first and second switchable reflectors, and first and second fixed reflectors. The first switchable reflector is disposed corresponding to the light source. The second switchable reflector is disposed corresponding to an eye. In a first mode, the first and second switchable reflectors are switched to a first state, and the incident light emitted by the light source is reflected by the first fixed reflector along a first optical path and then emitted to a first position of the eye. In a second mode, the first and second switchable reflectors are switched to a second state, and the incident light is sequentially reflected by the first switchable reflector, the second fixed reflector and the second switchable reflector along a second optical path and then emitted to a second position of the eye.
