Abstract
An improved laser gyro dither mechanism is shown utilizing a three-spring suspension system which isolates dither vibrational energy generated within the gyro and prevents that energy from passing to the mounting case of the laser.
Claims8
An improved dither mechanism, comprising:
- a first body having first and second coaxial hub attachment fixtures;
- a second body having a first inner toroidal attachment fixture substantially concentric with said first hub attachment fixture;
- a third body having a second outer toroidal attachment fixture whose diameter is greater than said first toroidal attachment fixture and is substantially concentric with said first toroidal attachment fixture and said hub;
- a first spring system angularly flexibly connecting said first toroidal attachment fixture and said first hub attachment fixture for angular resilience therebetween;
- a second spring system angularly flexibly connecting said first and second toroidal attachment fixtures for angular resilience therebetween;
- a third spring system angularly flexibly connecting said second toroidal attachment fixture and said second hub attachment fixture for angular resilience therebetween.

A laser gyro assembly having an improved dither mechanism, comprising:
- a first body comprising a ring laser body, a second body comprising a ring laser gyro case, a third body comprising a counterweight, and spring means angularly flexibly connected said first body to said second body, said first body to said third body and said second body to said third body.
An isolation system, comprising:
- a first body,
- means for vibrating said first body,
- third body means for counterbalancing the vibration of said first body,
- second body means for housing said first body and said third body means
- first, second and third spring systems for angularly flexibly connecting said first body, said third body means and said second body means allowing resilient relative angular rotation between said bodies, wherein the vibrational energy generated by said means for vibrating said first body is isolated from said second body means by said first, second and third spring systems.
