Problems solved by technology

[0007] A disadvantage of this arrangement is that manual manipulation of one adjustment screw may interfere with other adjustment screws or move the entire optical base structure
Such systems can also be adjusted with remote motors, such as stepper motors; however, these types of motors tend to be bulky and expensive and may require complex reduction gearing and other modifications
Another problem with some existing optical mounts is the lack of ability to reset the optical mount to a known position if it is disturbed or inadvertently moved

Embodiment Construction

[0040] Embodiments described herein relate to compact motorized drive mechanisms, including piezoelectric inertial drives, for use with mounts for optical adjustments. Such a mount can be configured to have little or no angular range limitation, availability of a center hole through the mount, positional stability in case of power loss of the mount, good sensitivity and relative to other optical adjustments The low cost of the motorized adjustable base. This motorized drive mechanism in the form of a piezoelectric inertial drive can be used in a wide variety of mounts for optical adjustment, including rotating mounts (such as swivel stages), optical mounts configured to adjust the angular tilt or orientation of optical instruments, Bases, such as mobile optical bases, which may include rotating or articulating configurations, and translational bases, which may include translational stages and the like. Such mounts may be used in particular in situations requiring the use of m...

Abstract

Adjustable mounts for optical elements or the like that may include absolute position information feedback. For some embodiments, position data may be generated independent of displacement measurement. Position data feedback may be provided to driver embodiments, such as piezoelectric inertia drivers, by a controller and used to achieve a desired position setting for an adjustable mount.
