Systems and methods for spectrally encoded imaging

摘要

A method of forming an image of a target that comprises illuminating a target with light, maneuvering an optical unit having at least one diffractive element in front of the target through a plurality of positions, capturing, during the maneuvering, a plurality of spectrally encoded frames each from a portion of the light that is scattered from a different of a plurality of overlapping segments along a track traversing an image plane of the target, and combining the plurality of spectrally encoded frames to form a composite multispectral image of at least a portion of said target.

1. A method of forming an image of a target, comprising:
illuminating a target with light; maneuvering an optical unit having at least one diffractive element in front of said target through a plurality of positions; capturing, during said maneuvering, a plurality of spectrally encoded frames each from light in a plurality of different wavelengths, each one of said plurality of different wavelengths is scattered from a different segment of a plurality of parallel segments along a scanning track traversing at least part of an image plane of said target; and combining pixel values of said plurality of spectrally encoded frames imaging each one of said plurality of segments by at least two of said plurality of different wavelengths to form a composite multispectral image of at least a part of said target.
