Abstract
A method for imaging a sample. The method includes, during a single acquisition event, receiving depth-encoded electromagnetic (EM) fields from points on a sample that includes a first depth-encoded EM field for a first point and a second depth-encoded EM field for a second point, and redirecting the first depth-encoded EM field along a first predetermined direction to a first location on a dispersing re-imager and the second depthencoded EM field along a second pre-determined direction to a second location on the dispersing re-imager. The method further includes spectrally dispersing the first depthencoded EM field to obtain a first spectrum, re-imaging the first spectrum onto a first location on a detector, spectrally dispersing the second depth-encoded EM field to obtain a second spectrum, re-imaging the second spectrum onto a second location on the detector, and detecting the first re-imaged spectrum and the second re-imaged spectrum.
