Analysis of Internal-Inertial Image Stabilization
Rachel Gross · Applied Optics · 1971
Internal-inertial image stabilization (IIIS) is a new form of image (or beam) stabilization. One of the components of an image-forming system is directly attached to a gyroscope to provide an inertial reference, thereby eliminating the usual vibration sensor/feedback/control subsystem, ordinarily required to produce vibration-free imaging. This paper discusses two basic optical configurations utilizing IIIS: that for the image surface mechanically coupled to the instrument, as in photographic applications, and that for a mechanically uncoupled image surface, such as an eye. Basic stabilization relations are derived, and a definition of stabilization factor is presented. Kinematic transfer matrix approaches are constructed which allow the effect on image stability of any system element to be determined. A method of deriving the coordinate transformation matrix corresponding to a given reflection matrix is presented.
