How to reduce reflections induced due to the plexiglass chamber during Laser Doppler Velocity measurements done in backscatter mode?

I am conducting an experiment to measure the velocity of the axial swirler in the closed plexiglass chamber using LDV (TSI Ar-ion Innova 70C) in back-scattering mode, as shown in the picture, at a...
