3.1 effective light intensity of transient detector responsivity theresponsibilityofinstantaneouseffectiveintensity measurementinstrument Receiving surface of the effective light intensity of transient detector probe, receives illumination signals corresponding to the time 1lx telecommunications No, the symbol R, the unit is lx/V. By the inverse square law can be obtained from the formula (1). E = Il2 (1) Where. E --- standard lamp in a standard detector receiving surface of the standard illuminance produced, lx; I --- standard lamp luminous intensity, cd; Distance l --- standard filament lamp to the detector plane receiving surface, m. At this time, if the optical signal generated by the detector is V, by the formula (2) calculate the effective light intensity of transient detector ring Degree should. R = EV (2) Wherein. R --- transient response of the effective light intensity measuring instrument, lx/V; The instantaneous voltage V --- transient light generated in the receiver, V. 3.2 instantaneous luminous intensity instantaneousintensity The degree of intensity of transient luminous source at a certain time, generally required to give instantaneous luminous intensity distribution curve over time Line, its sign is that I (t), in units of cd. Instantaneous luminous intensity calculation formula (3) as follows. I (t) = V (t) · Rl2 (3) Where. I (t) --- transient light source varies with time instantaneous luminous intensity, cd; V (t) --- the instantaneous source voltage transients generated at the receiver, V. ...
