Compact telescope configurations for light scanning systems and related methods are disclosed. According to an aspect, a system for imaging or relaying an image of an object includes a first optical element having a first focal length f1 for imaging or relaying an image of an object at the distance f1 from the first optical element. The system also includes a second optical element having a second focal length f2 for receiving an image of the object from the first optical element and for focusing an output of the image at the distance f2 from the second optical element on a side that opposes the first optical element. The first optical element and the second optical element are separated by a distance of approximately [Formula I], wherein r is the finite radius of curvature of the wavefront of light located at the object or image of the object.

摘要:
Methods and computer program products for quantitative three-dimensional (“3D”) image correction in optical coherence tomography. Using the methods and computer program products, index interface (refracting) surfaces from the raw optical coherence tomography (“OCT”) dataset from an OCT system can be segmented. Normal vectors or partial derivatives of the curvature at a refracting surface can be calculated to obtain a refracted image voxel. A new position of each desired refracted image voxel can be iteratively computed. New refracted corrected voxel positions to an even sampling grid can be interpolated to provide corrected image data. In some embodiments, clinical outputs from the corrected image data can be computed.
