Abstract
An optical system mounted on a confocal endomicroscope is proposed. The optical system may include a first laser coupled to a first optical fiber and a second laser coupled to a second optical fiber. The optical system may also include an optical fiber coupler that couples the first optical fiber and the second optical fiber into a third optical fiber such that the first beam propagating through the first optical fiber and the second beam propagating through the second optical fiber are simultaneously propagated through the third optical fiber. The optical system may further include an optical propagation module through which the first and second beams output from the optical fiber coupler are propagated.

An optical system mounted on a confocal endomicroscope for outputting a first beam of a first wavelength via a first laser and a second beam of a second wavelength via a second laser, irradiating an object with the first and second beams simultaneously, acquiring emission light emitted from the object, and processing the acquired emission light, the optical system comprising:
- the first laser coupled to a first optical fiber and the second laser coupled to a second optical fiber;
- an optical fiber coupler configured to combine the first optical fiber and the second optical fiber into a third optical fiber such that the first beam propagating through the first optical fiber and the second beam propagating through the second optical fiber are propagated simultaneously through the third optical fiber;
- and
- an optical propagation module through which the first beam and the second beam output from the optical fiber coupler propagate,
- wherein the optical propagation module comprises:
- an optical path through which the first beam, the second beam, and the emission light propagate;
- a plurality of optical members;
- a first collimator coupled to the third optical fiber;
- and
- a second collimator, coupled to a fourth optical fiber and connected to a probe for irradiating the object with the first and second beams,
- wherein the second collimator is configured to condense the first and second beams, corresponding to parallel light propagating along the optical path, to be transmitted through the fourth optical fiber,
