Tetrahedron type light pattern generation device, has optical device producing convergent beam, and displaying unit displaying beam pattern in tetrahedron shape, where optical device has convex lenses for increasing focusing of beam
The device has an optical device (11) producing convergent beam, and displaying unit (12) that displays beam pattern in tetrahedron shape. The optical device has a white or monochromatic light source emitting photons towards a concave mirror which reflects the light. The device (11) has two convex lenses placed side by side for increasing focusing of the beam so as to focus the beam in a point situated at an outlet of the device (11).
