Patent Images
1. A scanned beam endoscope, comprising:
- a scanning tip operable to scan a beam across a field-of-view (FOV); and
a light collector structured to collect scanned light affected by the FOV, the light collector being positionable relative to the scanning tip, wherein the light collector forms at least part of a trocar, the trocar including a housing having a bore therethrough dimensioned so that the scanning tip can be inserted through the bore.

Abstract
Apparatuses and methods for scanned beam imagers and scanned beam endoscopes having a positionable light collector are disclosed. In one aspect, a scanned beam imager includes a scanned beam source operable to scan a beam across a FOV and a light collector structured to collect light affected by the FOV. The light collector is positionable relative to the beam scanned by the scanned beam source. Scanned beam endoscopes and methods of performing endoscopy are also disclosed that implement the above teachings.

30. A method of performing endoscopy, comprising:
-
introducing a scanning tip of an endoscope tip into a body cavity; scanning a beam emitted from the scanning tip across a field-of-view (FOV) within the body cavity; positioning a light collector relative to the scanning tip, wherein the act of positioning a light collector relative to the scanning tip comprises inserting the light collector through a working channel in the scanning tip; and collecting at least a portion of light affected by the FOV with the light collector. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
