description The utility model belongs to the technical field of laser beam expanding, and particularly relates to a volume light generating device for Tomo-PIV flow field illumination, which comprises a laser source, a first concave lens, a convex lens, a second concave lens, a plano-concave cylindrical mirror, a diaphragm assembly, a first lens sleeve and a second lens sleeve. Wherein the first concave lens, the convex lens and the second concave lens are arranged in the first lens sleeve, the plano-concave cylindrical mirror is arranged in the second lens sleeve, and the first lens sleeve and the second lens sleeve are rotatably connected so as to be used for changing the beam expanding dimension of a circular light beam; the distance between every two adjacent lenses in the first concave lens, the convex lens and the second concave lens is adjusted based on the required beam expanding ratio and the focal length of each lens. According to the volume light generating device provided by the utility model, the shape and t
