Abstract
Traditionally, the photopyroelectric (PPE) technique is a contact phot othermal method. The work investigates the signal characteristics of t he non-contact PPE configuration. Below the modulation frequency of 5 Hz a two-dimensional theoretical approach is necessary due to axial an d lateral heat flow, whereas at higher frequency a one-dimensional mod el is convenient as well.
