• Canon patent
  • Imaging device curved
    • I approach the normal angle of incidence angle
    • Radius of curvature focal length of the imaging surface, the distance of the exit pupil is approximately equal
    • Optical fiber is generated by bundling etc.
  • Wavefront control element
    • And corrects the aberration by applying a phase difference wavefront of the light beam
