4D Movie Recording
One of the most prevalent types of microscopy is optical sectioning microscopy (including phase, nomarski and confocal microscopy), where the researcher can make 4-dimensional recordings (3D + time) of their biological samples. A diagram of this type of system can be seen in the figure below.
