Filed:

Dec 4, 2006

Appl. No.:

11/634322

Inventors:

Christopher A. Wiklof - Everett WA, US
Michael P. Weir - Blanchester OH, US

Assignee:

Microvision, Inc. - Redmond WA

International Classification:

A61B 1/06

US Classification:

600160, 600113, 600478

Abstract:

Apparatuses and methods for scanned beam imagers and scanned beam endoscopes that utilize multiple light collectors are disclosed. In one aspect, a scanned beam imager is disclosed. The scanned beam imager includes a scanned beam source operable to scan a beam onto a region of interest of an object. The scanned beam imager further includes a first light collector structured to collect light reflected from the region of interest and a second light collector positionable relative to the scanning tip. The second light collector structured to collect light transmitted through the region of interest.

Abstract:

A drive circuit includes a generator and a driver. The generator generates a signal having a period and a varying amplitude during a driving portion of the period, and the driver is coupled to the generator and drives a plate of an electrostatically drivable plant with the signal. The drive circuit may be used to drive a mirror plate of a comb-drive MEMS mirror.
