According to one aspect, embodiments herein provide a whole angle gyroscope comprising a central point, at least one mass arranged symmetrically about the central point, a plurality of transducers, each configured to perform at least one of driving and sensing motion of the at least one mass, and a processor coupled to the plurality of transducers, the processor configured to operate the plurality of transducers to drive the at least one mass in at least a first vibratory mode and a second vibratory mode, identify a rate dead zone of the whole angle gyroscope, and operate the plurality of transducers to apply a force to the at least one mass to reduce the identified rate dead zone of the whole angle gyroscope.

Calibration system and method for whole angle gyroscope

A non-contacting mensuration system including a light source for projecting light on a target; an imager having an image plane; a first optical subsystem configured to project a first image of the light on the target onto a first portion of the image plane of the imager; and a second optical subsystem configured to project a second image of the light on the target onto a second portion of the image plane of the imager so that two different images are obtained from different aspects simultaneously.
