摘要：
An optical coherence tomography (OCT) system includes: a light source； a multi-focal delay line； and a light detector. The multi-focal delay line includes: a positive lens； and an optical switch configured to: receive a light from the light source； selectively direct the sample light to the positive lens via a selected one of a plurality of light interfaces each located a different distance from the focal plane of the positive lens； and direct the sample light to an object to be measured. The light detector is configured to receive return light returned from the object to be measured in response to the sample light, and to receive a reference light produced from the light from the light source, and in response thereto to detect at least one interference signal. An associated OCT method may be performed with the OCT system.
