18. ower is used Nevertheless aside from safety concerns when high power lasers are used audience scanning effects can be unpleasant as they sweep past a viewer s eye This is because again the beam is so small that the entire beam s power scans across the pupil of the eye One easy solution is to use Pangolin s SafetyScan lenses They increase the divergence of the laser but only within the audience area Once affected by Pangolin s SafetyScan lenses the beam becomes bigger and because the beam is bigger this effectively lowers the irradiance beam power per unit area that enters the pupils of the audience members Due to the inverse square law that governs light this means that higher actual laser power can be used because the size of a laser beam is increased in both the horizontal and vertical dimensions The result is that higher laser power can be used and the show is much more effective The side benefit is that since the beam is bigger it also makes a much more pleasant softer audience scanning experience but only in the audience area When the SafetyScan lens is used correctly the laser beam is unchanged above the heads of the audience so the marbling effect seen in fog remains and the spectacle brilliance and drama of an audience scanning laser show are retained Mirror targeting can also be performed above the heads of the audience A SafetyScan lens can easily be mounted directly to the front of any laser projector either
19. s is mounted outside of a laser projector directly in front of the exit aperture as securely as possible However the lens may also be mounted inside the projector for greater security When mounted outside ideally a lens mount should be used which provides three degrees of adjustment Pangolin sells and has produced engineering drawings of such a mount that provides all three degrees of adjustment The mount designed by Pangolin is described in the next chapter Each degree of adjustment is described below The first degree of adjustment is obvious up down You adjust the lens upward and downward until the beam is diverged primarily in the audience area but where the beam is not diverged above the heads of the audience members The second degree of adjustment is left right You will notice that that in addition to affecting the beam divergence the lens will also effectively steer the beam leftward or rightward if the center of the lens is not placed precisely over the center of the X Y scanners For best results project a test pattern that has a vertical center line such as the Pangolin Orientation test pattern Move the lens leftward and rightward so that the center line of the test pattern is not affected remains vertical and centered throughout the projected image The third degree of adjustment is tilting the lens about the split at the top If the top portion of the lens is at an angle with respect to the light coming from the X Y s
