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 optical measuring device is provided. An actuator of a reference mirror set drives a reference mirror to move back and forth at a scan velocity. A first light source module transmits a first light beam to an optical coupling module transmitting two parts of the first light beam respectively to an examinee object and the reference mirror set. The first light beam then is reflected by the examinee object and reference mirror set and then transmitted to the optical coupling module and the processing unit. The second light source module transmits a second light beam to the examinee object. Then the second light beam is reflected and then transmitted to the second sensing unit. The second sensing unit provides a sensing signal to the processing unit which accordingly provides a value of the relative velocity. The thickness is calculated according to the relative velocity and the scan velocity.
