- 8. Apparatus comprising a scanned beam imager, wherein the scanned beam imager includes an optical dome and a dual-resonant-mirror scanner, wherein the optical dome has an optical axis, wherein the scanner is adapted to scan, about substantially orthogonal first and second axes, a beam of light through the optical dome within a field of view centered about the optical axis, wherein the scanner has first-axis angular extremes and second-axis angular extremes, and wherein the optical dome has a variable optical power distribution which gives a larger field of view than would be given by a constant optical power distribution.
- 13. Apparatus comprising a scanned beam imager, wherein the scanned beam imager includes an optical dome and a dual-resonant-mirror scanner, wherein the optical dome has an optical axis, wherein the scanner is adapted to scan, about substantially orthogonal first and second axes, a beam of light through the optical dome within a field of view centered about the optical axis, wherein the scanner has first-axis angular extremes and second-axis angular extremes, and wherein the optical dome has a variable optical power distribution which gives the scanned beam imager a smaller image resolution size proximate the optical axis than would be given by a constant optical power distribution.
- 18. Apparatus comprising a scanned beam imager, wherein the scanned beam imager includes an optical dome and a scanner, wherein the optical dome has an optical axis, wherein the scanner is adapted to scan a beam of light through the optical dome within a field of view centered about the optical axis, wherein the optical dome has a coating, and wherein the coating has a spatially variable transmittance distribution.
