Abstract

In parallelized microscopy, the optical lattices can be generated by multi-beam interference and realize parallelization imaging to improve the imaging speed. The optical lattices which depend on the system parameters such as the objective focal length, the distance between interference light sources and the aperture angle α, can affect the imaging quality. We built a simple optical system with the full conjugation between two Wollaston prisms and focal plane to obtain the optical lattices, and discuss the relations between the optical lattice and the system parameters. In the experiment, the interference fringes period of the optical lattice is 27.9μm for the focusing lens with focal length 150mm, but it is 46.5μm for the focusing lens with focal length 300mm.
