Abstract
An irradiation control system includes a radiation energy source for producing radiation energy in the form of pulses; a path defined for the radiation energy, between the radiation energy source and a surface to be irradiated with the radiation energy from the radiation energy source; an energy changing member provided in relation to the path and being effective to change the proportion of the radiation energy, irradiating the surface, to the radiation energy produced by the radiation energy source; a detecting device for detecting the irradiation of the surface with a predetermined amount of radiation energy; a driving device for changing the state of the energy changing member at least during a period from start of irradiation of the surface with the radiation energy to the detection of irradiation of the surface with the predetermined amount of radiation energy through the detecting device; and a control device for controlling the timing of production of radiation energy by the radiation energy source, in relation to the state of the energy changing member.
