PURPOSE:To expand the separation angle of laser beams by arranging two reflectors so that the incident and separation angles of two laser beams made incident with a fixed separation angle is expanded and projected. CONSTITUTION:Out of two laser beams B1, B2 separated and projected from an ultrasonic wave polarizer 17, one beam B1 goes straight on the optical axis without polarization and the other beam B2 is polarized and projected with a certain separation angle theta1 from the beam B1. In an angle amplifier 30, the beam B1 goes straight on the optical axis and the beam B2 is reflected and refracted by the reflectors 31, 32 to obtain a projection angle theta4 larger than the incident angle theta1. |
