Schematic of the beam trajectory for one tomogram with reduced speckle pattern. a. Beam trajectory with marked positions of spectra acquisitions; TAscan – time span between spectra acquisitions, Tresonant – resonant scanner period and time span between spectra acquisitions with the same lateral y position. b. Schematic view of the spectra acquisition positions in a case with denser sampling in the x direction. Acquired spectra with the same lateral y position can be regarded as one of a set of parallel tomograms separated by the distance Δy in y direction. The distance Δy can be easily controlled by the operator. This set of tomograms is averaged to create one tomogram with a reduced speckle pattern.
