Abstract

New methods of measuring such parameters of accelerated motion as angular velocity, angular and linear acceleration are considered. Measuring principles are based on the fact that there are inertial forces influencing the components of an optical-mechanical devices in noninertial frames of reference (rotating or under linear acceleration) and it leads to the components displacement and a changing of beam track relative to initial track. These changes are either the sources of noise or can be used to extract useful information about parameters of device accelerate movement. An instrument for measuring angular speed was suggested in the article.

Keywords: inertial frames of reference, angular velocity, angular acceleration, linear acceleration
