A miniature fiber-optic probe for optical particle sizing

A miniature fiber-optic probe has been developed for in situ particle size measurements. The probe is based on a near-forward scattering technique and makes use of a two-color seheme in which one wavelength is used for the size measurement while the second wavelength is used to monitor the presence...

Description
Summary:A miniature fiber-optic probe has been developed for in situ particle size measurements. The probe is based on a near-forward scattering technique and makes use of a two-color seheme in which one wavelength is used for the size measurement while the second wavelength is used to monitor the presence of a particle in the center of the scattering volume. Tests of the probe have shown particle size range and sensitivity similar to that observed using fixed lens train systems but with the advantages of portability, ease of remote access, anti inherent alignment stability.
