Step 1: Position camera, laser, and cylindrical lens

Align the laser so that its beam passes through the cylindrical lens, creating a vertical line rather than a point, and projects onto your target. Initially, the lens was the stem of a wine glass, but in this picture I use a cylindrical piece of acrylic. Position the video camera at a small angle (~15 degrees) from the laser.
