New laser accelerometer is presented. Proved method consists in the using of standing wave of coherent radiation in the
linear resonator as the sensitive element of the accelerated movement measurement. There are not in new accelerometer
named autonomous resonatory device (ARD) any matter parameters altering during movement of the resonator, attached
with object to be measured. It provides the best accuracy in the measurements. Volume part of generalized function of
eikonal for rectangle laser resonator is derived. Imaginary quantity of the eikonal provides the visible altering of
amplitude of interacting field of baghron in space. Optical schemes of the prototypes are presented. ARD can be applied
as measuring transducers for control of movement in demanded operating regions and it provides autonomous
measurement of acceleration of actual motion at free falling of object as against to all other accelerometers.
Classical theory of new autonomous laser accelerometer based on Galileo transformations, Maxwell equations and the
complement condition is proposed. Presented description allows the using of standing wave of coherent radiation in the
linear resonator as sensitive element of accelerated movement measurement. It appears that existence of field in form of
baghron is necessary condition of invariance of Maxwell equations in irregular moving systems. It is shown that vector
of radiation of infinite plane wave of light is equal to its wave vector. Generalized function of eikonal and Doppler-effect
are observed. Laws of baghronica were discovered. Theory of laser accelerometer based on quantum operators was
published with same results. Available future investigations are listed.
The most precise navigation systems are commonly based on at least 3 laser gyros and 3 mechanical accelerometers, based on moving or tensioned elements. Laser gyro's "dead zone" guides to existence of additive subsystems, and mechanical accelerometer accumulate the "error of zero" and does not measure during the free fall of an object. Here is found that dead zone on laser gyro characteristics is a result of the precession of momentum of pulse of ring baghron. The necessity of precise laser gyro tuning in Alert city, Canada, is discussed. The method to minimize the precession and to avoid the dead zone on the output characteristics is proposed. Therewith new solutions for autonomous control and navigation are discussed. Here is proposed the autonomous unit of sensors of irregular movement without moving parts and without ring laser resonators, disposed motionless on the object to be measured, based on unique unified 6 mini modules of the autonomous resonatory devices (ARD's). Another new solution could be computer 3D-mouse without pad and with 3 independent outputs for each axis of irregular movement, or the gear of control, which could be arranged in the marker or pen. ARD theory, the experiments and testing are discussed.
We create vibrosensor of new generation based on linear baghrometer. The same vibrosensor is available for precise measurement of amplitude, frequency and phase of vibration in wide range. Full consent of the proposed theory with experimental results is provided. Semiconductor laser based vibrosensor is presented.
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.
We name the phenomena 'optodynamics' when the light with a defined linear momentum or an angular momentum interacts with external forces and force momenta of an inertial system and there is no change in the dimensions and time of the moving system. A semiclassical theory is applied to elucidate the effects. The minimal measured angle of rotation for a laser gyro is defined. The additive decrease of the gyro scale factor due a standing wave non-plane phase front is obtained. It is found that the existence of 'dead zone' on the gyro characteristics is a result of the force momentum precession of the light in a ring resonator. Gyroscopic invariant of a ring laser is defined. Autonomous laser accelerometer is proposed.
The being advantages ofthe laser gyro against the precise gyro with rotating mass are the cost efficiency and the theoretical rapidity for practical systems. There have been unavailable the relevant publications on the laser gyro's necessary precision providing and also on its rapidity and on the nonstationary systematic errors excluding in real time. on the other hand it is known that output frequency of continuous wave linear laser is establishing, even in stationary conditions, during the transition time of 20 minutes up to 3 hour for different laser types '. Thus most traditional measurements with continuous wave laser are used in stationary conditions, when the counting of output characteristics is begun after the necessary transition time is gone 2 Since the output ofring laser is proportional to the active media generation frequency, the laser gyro has the nonstationary systematic error with the same value of the transition time. The investigations have been performed would be derived in the two groups. There are the laser gyro error's "mathematical models" and so-called "dynamic compensation methods" discussed in . The "dynamic compensation methods" are based on using of the temperature-depending elements in feed back system of the output signal. The both methods require the lasting measurements of laser gyro output in the stationary conditions to define the coefficients of the error model or to determinate the characteristics ofthe temperature-depending elements. These measurements must be repeated or the parameters must be automatically tuned for any other case. So it is unreasonable. The plasma heat regime influence on the precise ring laser output is considered in this work following to The case of the heat influence on the plasma without the dimensions changing is supposed. The thin effects, as modes drag, mode competition and radiation trapping ,do not be considered in order to the more clear idea. The each component of laser active media (electron gas, ion gas, excited atoms, etc.) has its own optical properties and puts its deposit in the ring laser output instability The analysis resulted in shows that, in case of constant electron and ion concentrations and when the frequency of electron-ion collisions is comparatively low, one obtains the Fresnel drag effect with electro-neutral atoms only.
