ABSTRACT:
A scanning laser system has a scan position controller to control an X-Y beam translator and a beam power controller to control a light source. A processor has accessible a table having a matrix of elements representing regions having spatial coordinates in at least two dimensions. A plurality of regions is required to define a space approximately sized as a human head. Each element contains a beam power variable indicative of radiation exposure at a corresponding region. Software resident in the processor has code for receiving a value of beam power incident on each region being scanned, for incrementing a stored beam power variable for each region if the beam power value is above a predetermined threshold, and for outputting to at least one of the scan position and the beam power controller a signal indicative of each region at which the beam power variable is above a predetermined value.
