Apparatus and method for stereo viewing in variable direction-of- view endoscopy |
摘要 |
A variable direction-of-view endoscope (74) with a spherical viewing window (34) symmetric about a symmetry plane (52) sealed to a distal end portion (18). The endoscope optical system can be adjusted to vary the direction of a view vector (22) through an unlimited range (50) about a pivot axis (23). The spherical viewing window (34) enables a process that switches the device between an initial configuration (54) and a final configuration (56), both having the same viewing direction (55). In addition to providing the user with an alternative to a possibly unfavorable viewpoint, this redundancy enables a stereo imaging process which captures (66) and displays (72) a stereo image pair (70) affording the user three-dimensional viewing.
