Scanning Laser Optical Tomography (SLOT) is a fast method
which can be used for imaging biological tissue or complete organs in a high
3-D resolution.
The Laser Zentrum Hannover e.V. (LZH) has filed a patent
application for a SLOT process, which was originally developed as a 3-D
fluorescence process for quickly scanning larger samples. SLOT, which can be
viewed as the optical equivalent to computer tomography, works with isotropic
resolution, that is, with the same resolution in all three spatial planes. It
simultaneously records transmissive, scattered and fluorescent light. Samples
can thus be imaged with a 3-D resolution of at least 1/1000 of the object size,
in a short time. The goal of the current project is further development of this
promising technology, so that an imaging speed of 20 seconds for 600 individual
projections can be reached.
