LDA CALIBRATION AT INRIM: A PORTABLE DEVICE

A. Piccato, R. Malvano

Abstract

INRIM has been developed a LDA calibrator for a speed range between 0.03 m/s and 14 m/s. The device is composed by a rotating disk with a surface manufactured that simulates the tracer particles. The device is also composed by an alignment system to adapt the calibrator to different focal lengths and beam angles. The particularity of this prototype consists in its solidity and portability. Actually, the target of this device is not the improvement of the general measurement accuracy for LDA calibrators but it has been designed to be portable in order to be used as a possible transfer device for LDA calibration comparisons.
