High-Speed Photography Of Light Beams Transmitted Through Pinhole Targets

A method of high speed photography is presented. It was designed and performed in order to study temporal behaviours of plasma closure effects of pinhole targets in laser plasma experiments. A series of high speed photographs were taken for the laser beam transmitted through the pinhole targets. Spatially resolved and integrated temporal histories of closure effects were observed, respectively. Some physical information about closure effect, for example, closure speed and so on was studied.
