Studies On Degree Of Freedom For High-Speed Photography

In this paper we try to perfect information theory of high speed photography (HSP), which are theoretically and practically analyzed with theory on degree of freedom (DOF). Generally speaking, information theory of HSP should be able to used for evaluating HSP systems and HSP methods, and for the best it should be able to show the way to upgrade HSP's performances and throughly exploits resources of the recording light used as information carrier. As a method for studying information theory of HSP, optical DOF theory should be utilized at first, in which particularities of HSP systems, statistical rules of measured events and know-how from long-term HSP's practices must be taken into consideration.
