Abstract
A system may include a projector subsystem in a theatre projecting fight toward a screen, a sensor measuring light levels of the projected light, and a processing device. The projector subsystem may project light such that there is a hazardous light area and a non-hazardous light area of an audience seating area. The processing device may receive a measured light level of projected light from the sensor. The processing device may determine a second light level between the hazardous light area and the non-hazardous light area based on the measured light level and the position of the light projected over the audience seating area. The processing device may compare the second light level to an unsafe threshold light level. The processing device may determine a configuration for the system such that the light level of projected light in the non-hazardous light area is less than the unsafe threshold light level.
