The paper presents a novel approach to detect and monitor excited biomolecules by means of holographic registration of thermal disturbances produced by their radiationless deactivation. The photoacoustic and photorefractive methods do not provide any data on spatial distribution of these disturbances. Holographic interferometry allows one to obtain in a single shot a 2D image of the area under study containing information on spatial distribution of local variations of refractive index induced by temperature variations. The method feasibility is demonstrated on the monitoring of photosensitized generation and radiationless deactivation of singlet oxygen in water.
