Devices and methods for polarization-sensitive optical coherence tomography and adaptive optics

摘要

The present disclosure includes disclosure of devices, and methods to resolve microscopic structures. In at least one exemplary embodiment, a visualization apparatus comprises a source arm having a light source operable to emit a light beam, wherein the light beam defines a beam pathway, a reference arm comprising a reflecting surface positioned within the beam pathway, a sample arm comprising a wavefront sensor, an adaptive optics wavefront corrector, and a target, each of which are positioned within the beam pathway, wherein the adaptive optics wavefront corrector is operable to compensate for at least one aberration in the light beam, a detector arm comprising a beam detector positioned within the beam pathway, wherein the beam detector is operable to detect the reflected light beam from the reference arm and the target, and wherein the visualization apparatus is operable to minimize at least one aberration of the target.

1. A visualization apparatus, the apparatus comprising:
a source arm comprising a light source operable to emit a light beam, wherein the light beam defines a beam pathway; a reference arm comprising a reflecting surface positioned within the beam pathway and capable of reflecting the light beam; a sample arm comprising a wavefront sensor, an adaptive optics wavefront corrector, at least two 90/10 pellicles, and a target, wherein each of the wavefront sensor, the adaptive optics wavefront corrector, the at least two 90/10 pellicles, and target are positioned within the beam pathway, wherein the adaptive optics wavefront corrector is operable to compensate for at least one aberration in the light beam, wherein the at least two 90/10 pellicles are operable to reduce diattenuation of the apparatus via a first 90/10 pellicle of the at least two 90/10 pellicles that reflects about 10% of a first incident light beam directed at the first 90/10 pellicle parallel to a top surface of an optical table towards the wavefront sensor, and a second 90/10 pellicle of the at least two 90/10 pellicles that reflects about 10% of a second incident light beam directed at the second 90/10 pellicle perpendicular to the top surface of the optical table; and a detector arm comprising a beam detector positioned within the beam pathway, wherein the beam detector is operable to detect the reflected light beam from the reference arm and light beam returning from the target; wherein the visualization apparatus is operable to minimize at least one aberration from an optical element or the target.
