FIELD: machine building.
SUBSTANCE: procedure consists in lightning object with optical radiation, in conversion of reflected signal into autodyne signal and in recording its power. Further the signal is digitised and analysed. Value of object acceleration is determined by solving an inverse problem defining minimum of functional: 
where a is linear acceleration of an object, Pexsp are experimental values of the autodyne signal, Ptheor are theoretical values of the autodyne signal, θ is phase incursion of the autodyne signal, t is time interval of the autodyne signal. The exact value of global minimum is found by the method of descent along sought-for parametres θ and a.
EFFECT: measurement of acceleration at micro-shifts in wide dynamic range of accelerations and upgraded accuracy of absolute acceleration measurement within limits meeting modern precision devices.
