Abstract
We propose the laser accelerometer for guidance and navigation as component for control systems. The linear laser has been sued to provide the sensitive light standing wave - baghron - in the proposed sensor. The custom optical components and the photodiode have been used to convert an interference pattern intensity signal to a reading of the acceleration. The main goal of the proposed efforts is to demonstrate the ability of the sensor to measure on the vehicle an acceleration of an irregular movement with respect to an inertial system in wide working range. Proposed sensor is being without any dead zone or hysteresis on output characteristics, it doesn't measure the gravity without motion and could be used in a large number of important applications. There are not in the accelerometer any parameters of the resonator attached/fixed with the object to be measured, which would be altering during the movement of the object. There is not any moving part or tensioned element in the proposed accelerometer defended with the US patent No 5,652,390. Date of patent: July 29, 1997. Class: 073-657.000.
