Extended Lattice Light-Sheet with Incoherent Holography

Recently, lattice light-sheet instruments and imaging technology have shown a great improvement in exploring the dynamics of life at subcellular resolution. However, to reconstruct 3-dimensional structures the objective lens or the sample stage are invariably moved. Invention of incoherent holography lattice light-sheet (IHLLS) using FINCH provides quantitative information on the state and size of subcellular changes of neurons over the visible spectrum. The technique allows both faster three-dimensional amplitude as well as phase imaging without moving either sample stage or the detection objective. Amplitude and phase measurements provide intrinsic instrumental simplicity, larger scanning area, and higher resolution when compared to the original LLS schemes. IHLLS is built as an additional detection arm of an original lattice light-sheet (LLS) system. In this chapter, we review the evolution of IHLLS to address its feasibility and limitations.
