An Introduction to the Lock-In Amplifier and a Mie Scattering Experiment
written by Jessie Petricka
A three week laboratory sequence which begins with an introduction to the lockin amplifier and builds to an automated measurement of Mie scattering. In week one, the lockin introduction builds familiarity using a LabVIEW simulation and a pre-recorded CD. Students then use the lockin to measure a frequency response curve of an acoustical resonance in a glass beaker. Then, as a prelude to a precision measurement, they also do an optical measurement of ND filters. In week two, the Mie scattering is automated using LabVIEW with GPIB and a stepper motor controller. Finally, in week three the students perform chi-square data analysis of their scattering data to find the diameter of the scattering media.
