Titel:
Improving the accuracy of laser self-mixing interferometry for velocity measurement 
Abstract:
Self-mixing interferometry (SMI) employs fewer components, leading to a compact, robust and low cost system. In this paper, the main error sources of SMI for velocity measurement are analyzed and a simple error model is proposed. The dependence of signal amplitude and relative error on the incident angle is acquired by experiment. With the comparison of simulations and experiments, the proposed model is proved that relative errors could be reduced by decreasing the incident angle. To reduce the...    »
