FISHEYE LENS DOT PROJECTOR

In some implementations, a dot projector optic may include a collimating lens; a fisheye lens; and a dot aberration correction element disposed between the collimating lens and the fisheye lens. An input to the fisheye lens, from the dot aberration correction element, may be associated with a first...

Zusammenfassung:	In some implementations, a dot projector optic may include a collimating lens; a fisheye lens; and a dot aberration correction element disposed between the collimating lens and the fisheye lens. An input to the fisheye lens, from the dot aberration correction element, may be associated with a first field of view angle. An output from the fisheye lens may be associated with a second field of view angle that is larger than the first field of view angle.
