Paper Abstract

In order to maximize the analytical performance of thermal lens calorimetry, it is useful to know the system frequency response which is formed from the product of the Fourier transform of the thermal lens impulse response with the frequency components of the excitation waveform. This result is used to describe the variation in the small signal response of double beam thermal lens calorimetry with chopping frequency. This information allows the evaluation of the trade-off between signal averaging rate and frequency roll-off to determine an optimal chopping frequency.
