title: Laser stroboscopic photography. Technique for cell orientation studies in flow.
abstract: Squamous cells in fluid flow are photographed using a laser stroboscopic technique. The technique provides either dark field or phase contrast multiple images of a cell on a single frame of film at resolutions permitted by the thickness of the cell stream. Cell orientation, velocity and acceleration are obtained from these photographs for evaluation of flow system performance.
