Abstract

The optical deflector is useful where large aperture and/or multiple light beams are to be steered and stabilized. The entrance light beam (top) is split by reflecting surfaces R1 and R2, as shown in the figure. The beam sections are mutually realigned by internal reflecting surfaces R1' and R2'. Surfaces R1' and R2' rotate together about the y-axis. R1 and R2 rotate with the y-axis about the x-axis.

Multiple Beam Combining Optical Deflector

The optical deflector is useful where large aperture and/or multiple light beams are to be steered and stabilized. The entrance light beam (top) is split by reflecting surfaces R1 and R2, as shown in the figure. The beam sections are mutually realigned by internal reflecting surfaces R1' and R2'. Surfaces R1' and R2' rotate together about the y-axis. R1 and R2 rotate with the y-axis about the x- axis.

The optical light beam combination is achieved at R1 and R2 by selective transmitting reflector. Light beams are incident on the external reflecting surfaces of R1 and R2 from opposite sides along the x-axis. An additional reflector R3 is located beneath the roof formed by R1 and R2. R3 is centered on the x-axis parallel to R2. Beams arriving inside the roof formed by R1 and R2 are deflected by R3 so that all beams proceed parallel to common axes. R3 revolves about the x-axis with R1 and R2.
