This paper presents the most recent mathematical modelling and procedure for Laser-Doppler Anemometers (LDA) calibration used by the Brazilian National Institute of Metrology Institute, the National Institute of Metrology, Quality and Technology (Inmetro). Here we calculate the fringe spacing calibration coefficient (C ? ) and the Burst Spectrum Analyser (BSA) calibration coefficient (C ??? ). Using these two calibration coefficients we can calibrate a LDA in a determinate velocity range.
