The paper presents preliminary results of testing of paintings on canvas response to environmental fluctuations. The research was made on the model paintings varying in the type of canvas support used, gelatine size and additional consolidated size. Optical Coherence Tomography (OCT) was used in particular application – where even semi-transparency of layers of investigation object is not required – as a profilomeric tool for monitoring the response of the painting surface to climatic changes. The tested samples, strained on metal stretcher with force sensors, were examined insite climatic chamber, in conditions designed according to climate parameters usually experienced in sacral interiors and museums. During a few hours long cycle of moistering and drying, the displacement of a chosen point on the surface was monitored and recovered simultaneously in three dimensions (X, Y, Z), with micrometer precision, and the data were recorded at the hard drive. The findings of tests indicate the relation between the technological aspects of paintings on canvas and their reaction to periodical climatic changes.
