Optical biometer

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.
