Experimental setup for PIV measurements with a deformable mirror. Laser light (561 nm) is transformed to a light sheet by a cylindrical lens. Seeding particles within a water basin scatter light through a microscope objective (MO) to a deformable mirror. A beam splitter (BS) reflects the modulated light which is focused by a lens (L) to a CCD camera
