A new analytical technique-Photothermal Radiometry (PTR) is introduced in this paper. We set up a PTR measurement system and obtained the optical absorption spectrum of solids by using Ce2O3 powder and a green leaf as the testing sample. Calculated PTR signal-to-noise ratios are found comparable with thsoe observed.
