“…Therefore, the wavelength of the beam needs to be altered (compensated) to incorporate any changes in these parameters. [252][253][254][255][256] The advantages of interferometry include the inherent sensitivity and accuracy of interferometric measurements offered by an instrument that does not need to be calibrated because 251 Polymer Chemistry Review the wavelength of the laser light source provides a precisely known wavelength. In addition, the ability to collect data at high speed allows for the real-time characterization of rapid photopolymerization reactions, among others.…”
