Resumo
Comparative determinations of the noise equivalent power (NEP) of open-ended photothermal cells are performed using LiTaO3 and LiNbO3 crystals with and without indium tin oxide (ITO) transparent electrodes. Open-ended cells can be used for in vivo measurements, which are important when considering the achievability for continuous monitoring of a plant, verifying, for example, the effect of water stress or UV-B radiation on a leaf. We also show the results obtained with one of these cells in the determination of photochemical loss of plant leaves. (c) 2007 Elsevier B.V. All rights reserved.
