Not Accessible

Your library or personal account may give you access

Abstract

This work reports a packaged optical fiber axicon probe generating Bessel beam and Bessel beam interferometry technique for measuring RI of hazardous liquid HCL, H2SO4. The measurement resolution of our system is 1*10 "4± 0.0007.
