Applicability of light depolarization technique to crystallization studies

In spite of interpretational weaknesses, further development of light depolarization technique seems to be justified by potentially short response time. LDT may appear useful for studying rapid crystallization processes (above 1 kHz sampling frequency), which cannot be followed by measurements of density, X-ray diffraction or calorimetry. However, the LDT data either have to be combined with independent measurements of crystal thickness, or treated as a 'crystallization characteristic' per se, quantitatively inconsistent with calorimetric, volumetric or X-ray diffraction data.
