FIGURE 1. A diagram of rigid-body motions shows the six possible degrees of freedom. For rotationally symmetric parts, the axis of symmetry is assumed to be along the Z axis.

Aspheres: Removing alignment errors from measurements of spherical, aspheric, and freeform optics

Optical surface measurements include alignment error from rigid-body position uncertainty; challenges exist when fitting such errors on aspheres and freeforms.

James C. Wyant with Maria Ruiz in 2014, a first-year graduate student at the College of Optical Sciences, who that year received a Louise Wyant Memorial Scholarship in Optical Sciences. James Wyant and his family are now contributing $2 million and SPIE $500,000 to an educational-funding initiative for optics and photonics.

FIGURE 1. A real laser beam will have a divergence angle (θR) greater than that of an ideal Gaussian beam (θG); the beam’s wavefront is planar in the near field near the beam waist and curved in the far field.

FIGURE 1. An illustration of liquid-crystal metasurface (LCM) beam steering depicts its operation. The incident light is TM-polarized. Shown here, the LCM steers to two different output angles (a and b), determined by the spatial frequency of the phase-modulation pattern applied to the array of tunable resonators on the LCM (c and d). Higher spatial frequencies steer the output beam closer to the incident beam.
