Abstract: An optotype calibration method is disclosed. The optotype calibration method includes steps of: (a) when a first optotype and a second optotype located outside an observable area, moving the observable area from an original position until the first optotype or the second optotype appears in the observable area; (b) adjusting a focus mechanism to make the first optotype and the second optotype close to each other; (c) moving the observable area back to the original position; and (d) repeating the steps (a)˜(c) until the first optotype and the second optotype align with each other.

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 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.
