An apparatus comprises an array of light emitting diodes (LEDs), each LED in the array having an asymmetric optical characteristic. The asymmetric optical characteristic of a first subset of LEDs in the array is oriented at an angle of 90&#xb0;, 180&#xb0;, or 270&#xb0; with respect to the asymmetrical optical characteristic of a second subset of LEDs in the array. The apparatus may be the array of LEDs or an illumination system comprising a light source comprising the array of LEDs. Methods of manufacturing the apparatus are also provided.

Uniforming an array of LEDs having asymmetric optical characteristics

A beam-shaping optical system suitable for use with optical coherence tomography includes a beam-shaping body having a beam-shaping element and an alignment feature. An optical fiber is coupled to the alignment feature. The fiber has a fiber end configured to emit an electromagnetic beam. The fiber and the body are configured to direct the beam into the beam-shaping element such that the beam is shaped solely by reflection into an image spot.

Reflective optical coherence tomography probe

Systems and methods for multiple-pass stripping of an optical fiber are disclosed. The method include irradiating a first portion of the coating with a first beam of radiation having a wavelength at which the coating is substantially transparent and an intensity that exceeds the optical-damage threshold of the coating to form a first damaged coating portion. The method also includes receiving at least a portion of the first radiation beam and redirecting it as a one or more redirected radiation beam to either the first portion of the coating to assist in forming the first damaged coating portion, or to one or more second portions of the coating to form one or more second damaged coating portions. The method additionally includes exposing a section of the central glass portion damaged portions of the coating.

Systems and methods for multiple-pass stripping of an optical fiber coating

Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body having a folded optical axis and at least one alignment feature that supports the end of an optical fiber adjacent an angled planar end wall. The monolithic body also includes a total-internal reflection surface and a lens surface that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot at the image plane.

Monolithic beam-shaping optical systems and methods for an OCT probe

An OCT optical probe component comprising: A rod having a first end and a second end, a lens situated proximate to the second end of the rod, the lens having a surface with an inner zone a, and an outer zone b, wherein the inner zone a is associated with the focal length fla, and said outer zone b is associated with the focal length flb, such that optical probe component is multi-focal, the optical probe capable of imaging at multiple image planes, via the lens of an object adjacent to the first end of the rod, wherein the at least two images are separated by a distance d, wherein d&#x3e;1 mm.
