Abstract

The temperature dependence of the resonance frequency for a cantilever of a shape-memory alloy vibrated photothermally is described. The temperature coefficient of the resonance frequency of the alloy with memory for shape recovery was positive (2.0 × 10-2/°Q) at a temperature near the martensitic transformation, in contrast with it being negative (–2.2 × 10-3/°C) for the alloy without memory. The technique of using one laser for both excitation and detection was adopted for determining the resonance frequency of the photothermal vibration.
