Abstract
A system and method for controlling the energy of light pulses for use with a projection optics system is provided. The system includes a light source configured to emit light pulses, a transmission element configured to transmit a first part and a second part of an active light pulse, the first part being transmitted to the projection optics system, and a feedback system including a detector configured to receive the second part of the active light pulse and determine a total measure of energy of the active light pulse, and a control unit configured to receive the total measure of energy and in response control an amplitude of a subsequent light pulse. In some implementations, the control unit may additionally set a threshold value for communication to a comparator to compare against the total measure of energy and in response control the width of the active light pulse.
