We present?PhotonSTR-T18, a LabVIEW based package for the calculation of intensity correlation and structure functions from the measurement of the time of arrival of scattered photons from soft materials.?PhotonSTR-T18can calculate the intensity correlation and structure functions of the scattered photon history from one (auto-mode) and two independent sets of collected data (cross-mode) Here, we present a description of the software operation and functionalities. To validate our package capabilities, we present the analysis of data acquired from model colloidal nanoparticles embedded in polymer matrices. Our results compare quantitatively well with previous results, thus validating our software’s applicability in the field of photon correlation spectroscopy.
