Abstract: An optical biometer including a light source, a first-stage coupler, a first and a second second-stage coupler, a first and a second optical path difference generator, a first and a second optical component set, a first and a second detection device is disclosed. The first-stage coupler receives an incident light from the light source and emits first and second first-stage lights. The first second-stage coupler receives the first first-stage light and emits first and second second-stage lights. The second second-stage coupler receives the second first-stage light and emits third and fourth second-stage lights. The first/second optical path difference generator generates the first/fourth second-stage light with the first/second optical path difference. The first/second optical component set emits the second/third second-stage light to a first/second position of an eye and receives a first/second reflected light. The first/second detector receives a first/second detection light.

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 detection device and an operation method thereof is disclosed. The optical detection device includes a light source, an optical coupling element, a reference optical path modulation element and a data processing element. The light source provides an incident light. The optical coupling element divides the incident light into a reference light and a detection light and emits them to the reference optical path modulation element and the sample to be tested respectively. The reference optical path modulation element reflects the reference light and rapidly changes the light path of reference light. The optical coupling element interferes the reference light reflected by the reference optical path modulation element and the detection light reflected by the sample to be tested to generate an optical interference signal. The data processing element receives and analyzes the optical interference signal to obtain an optical detection result about the sample to be tested.

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.
