Query: Light Sheets with Extended Length   High resolution light-sheet optical microscopy requires illuminating a sample
by a thin excitation light sheet with large area. Here, we describe methods for
producing light sheets with extended length, as compared to Gaussian-beam-type
diffracting light sheets with the same thickness, without scanning or dithering
the light beams.
