Transient Grating of Rolled Polyethylene Films

Description

Each text file includes meta data at the beginning. PM Period and grating periods are in microns. dt is the time step in microseconds. Data follows this section. The data is the raw data plus a constant that brings the data near 0 (The raw data can have large voltage offsets from 0 due to the detector used). The data is broken up into numerous measurements at + and - heterodyne phases. Each data set is preceded by the phase of the data. Note, the data is in mV, though the magnitude is not important for interpreting the results. For help in interpreting the raw data, please contact the authors.
