at this pixel average beam power at this pixel total number of times this pixel has been scanned average number of times this pixel has been scanned time when this pixel was first scanned by the beam time when this pixel was last scanned by the beam pulse width experienced at this pixel and maximum power allowed at this pixel the u201c total accumulated beam power at this pixel u201d is computed by simply adding the instantaneous beam power to the current value stored in the u201c total accumulated beam power at this pixel u201d this value may be used to monitor and visualize the total power delivered in each area of the audience this data element may also consist of separate data elements for red green and blue beam power if it is desired to monitor and attenuate these separately the u201c average beam power at this pixel u201d is related to the u201c total accumulated beam power at this pixel u201d in that it represents a beam power that is accumulated over time and it is calculated using the instantaneous beam power as an input however the u201c average beam power at this pixel u201d requires an additional level of computation in order to produce a value that represents an average over time this may be.
