| Abstract: | In this paper, the relationship between light measuring range and optical system of SLR (Single Lens Reflet) camera has been analysised. The calculating model of Light measuring system has been established, and the calculating method and formulae light measuring power have been arived. By calcutating ths light track, writing computer programme, the examples of some parameters of light measuring systems and their light measuring ranges have been given. |
