Pulsar uses a combination of rotating and fixed mirrors and a strong laser source to achieve an total internal reflection on a concave circular mirror. Due to the laws of optical reflection of light, the resulting image resembles a star. Because the angle of reflection is changed all the time due to a moving mirror, the star formations appear to pulsate and change their geometrical pattern. The title 'pulsar' refers to very dense neutron stars that emmit radiowaves which reach earth in a so called 'lighthouse' effect, or pulses, whereby the star appears to pulsate extremely accurately. www.balintbolygo.com
