摘要： An optical viewing assembly (130) for transferring image information from one image modifying device (78) to another image modifying device (74) includes first and second clamping portions (14) integrally formed at opposite ends of a hollow sleeve (12). Each clamping portion (14) has a pair of clamping legs (24, 26) that are separated from the sleeve (12) by a circumferential slot (16) to permit movement of the clamping legs (24, 26) toward and away from each other by manipulation of a locking lever (44). Movement of the clamping legs (24, 26) toward each other reduces a cross dimension of the clamping portions (14) to thereby clamp an image modifying device therein. Conversely, movement of the clamping legs (24, 26) away from each other increases a cross dimension of the clamping portions (14) to thereby release a clamped image modifying device.

摘要： An optical transducer (200) comprises a light source (230) for emitting radiant energy, and an elongate light collector (204) positioned for receiving radiant energy from the light source (230). Radiant energy projected by the light source (230) is received on the light collector (204) and is transmitted along a length of the light collector (204). A portion of the transmitted radiant energy exits the light collector (204) along its length through a gap (205) to thereby vary the intensity of light along the light collector length. At least one photosensor (232) is positioned for detecting the intensity of radiant energy incident at a particular location on the light collector (204). In this manner, the intensity of radiant energy detected by the at least one photosensor (232) is indicative of at least relative position between the incident radiant energy and the at least one photosensor (232).
