LIGHT STIRRER

摘要

This invention provides an optical mixer to convert coherent light into virtually incoherent light by using a hollow motor to rotate the optical mixing plate at the peripheral speed of at least 1800 times per minute relative to the laser beam diameter. This invention comprises an optical mixing plate 8 installed on the light path and a hollow motor 2 to rotate said optical mixing plate 8 at high speed, and is capable of converting the laser beams incident on said optical mixing plate 8 into virtually incoherent light.
