Methods and systems for generating non-diffracting light sheets for multicolor fluorescence microscopy

摘要

Methods and systems for generating non-diffracting light sheets for multicolor fluorescence microscopy are disclosed. A method for generating a non-diffracting light patterned Bessel sheet comprises transmitting an input light beam through a Fourier transform lens the input light beam has a spatial intensity pattern at a first plane, and a Fourier plane is formed after the Fourier transform lens to obtain a first light beam; transmitting the first light beam through an annulus mask to obtain a second light beam; and transmitting the second light beam through an excitation objective lens to form a non-diffracting patterned light sheet. A method for generating a non-diffracting light line Bessel sheet comprises transmitting an input light beam at a first lane through an annulus mask to obtain a first light beam; and transmitting the first light beam through an excitation objective lens to form a non-diffracting Bessel light sheet.
