Picture.Regrettably, although there has been proposed the axial scanning method that some are focused based on space-time, corresponding axis is not suggested that
To synchronizing detection method, i.e., currently there is not yet the report of relevant three-dimensional high-speed wide visual field chromatography imaging method.Specifically, existing
It is mainly that light pulse is changed to optical dispersions devices such as, gratings by adjusting prism based on the axial scanning method that space-time focuses
Group velocity dispersion, and then change focusing surface and realize scanning.Change group velocity dispersion the result is that so that after dispersion different frequency
The distance between light beam changes, so that the change of light pulse converged position, i.e. focusing surface change in location.However, above-mentioned
The approach for changing group velocity dispersion is constrained by machinery inertial, limits the speed of axial scan.In addition, for realize clearly at
Picture, end of probe image sensor (such as CCD, sCMOS) needs synchronizing moving, to keep the object-image relation of focusing surface and image planes, and it is high
Fast Mechanical Moving image sensor is unpractical, therefore three-dimensional high-speed wide visual field chromatography imaging technique speed is still unhappy.
