Abstract
A laser projector includes a laser, scanning mirrors projecting a laser line image on a surface, a computer including an algorithm controlling a speed of the laser line image, and a computer screen having a user interface. The user interface includes a throttle control which modifies the speed control algorithm permitting an operator to reduce the maximum speed of the projected laser line image using the throttle control, thereby improving the visibility of the laser line image. For example, a method of improving the visibility of a projected laser line image includes projecting a laser line image on a surface to determine the visibility of the laser line image and decreasing the maximum scanning speed of the projected laser line image if the visibility of the laser line image is insufficient.
