1. An apparatus for scanning a beam on a luminal organ or surgical cavity which comprises:
a proximal section;
a tether that connects a distal section to the proximal section; and
the distal section comprising;
a transparent portion;
a two-dimensional (2-D) optical projector that projects an optical beam in a 2-D closed curve optical pattern;
focusing optics that receives the projected optical beam in the 2-D closed curve optical pattern and directs and focuses the beam; and
a reflective rotary or angular scanner that scans the projected optical beam focused by the focusing optics from within the distal section through the transparent portion, the optical projector, focusing optics, and reflective scanner operating on the projected beam in series within the distal section prior to projection of the projected beam from within the distal section through the transparent portion toward the luminal organ or surgical cavity.
