Improvement of methods and means of control of deviations from straightness by using acousto-optic heterodyne laser measuring systems
The article deals with the construction of high-precision acoustooptic (AO) heterodyne laser measurement systems for monitoring deviations from straightness when working in continuous mode with phase-digital Δφ(Δl y )–ΔNout and frequency-digital Δf(Δl y )–ΔNout transformations, as well as in...

| Summary: | The article deals with the construction of high-precision acoustooptic (AO) heterodyne laser measurement systems for monitoring
deviations from straightness when working in continuous
mode with phase-digital Δφ(Δl
y
)–ΔNout and frequency-digital
Δf(Δl
y
)–ΔNout transformations, as well as in pulse mode. It discusses
the use of solid-state AO modulators, phase-locked loop systems
phase and frequency together with the fiber phasemodulaters and
precision ADC. The variants of linearization of the transformation
function, increasing the resolution are proposed. It discusses
the possibility of implementing laser measurement systems with
support channels and admittance control. |
