Abstract
An alignment viewer apparatus (40) for assessing optical path alignment of a stereoscopic imaging system (10), the apparatus (40) having a left reflective surface (42l) for diverting light from a left viewing pupil (14l) toward a beam combiner (44) and a right reflective surface (42r) for diverting light from a right viewing pupil (14r) toward the beam combiner (44). The beam combiner (44) directs the diverted light from left and right viewing pupils (14l and 14r) to form a combined alignment viewing pupil (36), allowing visual assessment of optical path alignment thereby.
Claims28
An apparatus for assessing optical path alignment of a stereoscopic imaging system, the apparatus comprising:
- a) a left reflective surface for diverting light from a left viewing pupil toward a beam combiner;
- b) a right reflective surface for diverting light from a right viewing pupil toward the beam combiner;
- and
- c) the beam combiner directing the diverted light from left and right viewing pupils to form a combined viewing pupil, allowing visual assessment of optical path alignment thereby.
A system for assessing optical path alignment of a pupil-forming stereoscopic imaging apparatus, the system comprising:
- a) an image generator providing a left test pattern to a left image-forming light modulator and providing a right test pattern to a right image-forming light modulator;
- b) a left reflective surface for diverting modulated light away from a left viewing pupil and toward a beam combiner;
- c) a right reflective surface for diverting modulated light away from a right viewing pupil and toward the beam combiner;
- and
- d) the beam combiner directing the diverted light from left and right viewing pupils to form a combined viewing pupil for assessment of the optical path alignment using the overlaid left and right test patterns.
A system for assessing optical path alignment of a pupil-forming stereoscopic imaging apparatus, the system comprising:
- a) an image generator providing a left test pattern to a left image-forming light modulator and providing a right test pattern to a right image-forming light modulator;
- b) a left reflective surface for diverting modulated light away from a left viewing pupil and toward a beam combiner;
- c) a right reflective surface for diverting modulated light away from a right viewing pupil and toward the beam combiner;
- d) the beam combiner directing the diverted light from left and right viewing pupils to form a combined viewing pupil;
- and
- e) a sensor disposed proximate the combined viewing pupil for obtaining an image comprising combined left and right test patterns.
A method for assessing optical path alignment of a stereoscopic imaging system, comprising:
- a) forming a left test pattern at a left image-forming light modulator of the stereoscopic imaging system and forming a right test pattern at a right image-forming light modulator of the stereoscopic imaging system;
- b) diverting light from a left viewing pupil toward a beam combiner;
- c) diverting light from a right viewing pupil toward a beam combiner;
- and
- d) combining the diverted light from left and right viewing pupils to form a combined viewing pupil for visual assessment of the optical path alignment.
