The subject of the study is presentation of optical techniques for the measurement of local values of overall heat transfer coefficient. Measuring systems based on Schlieren and interference systems, built either in classical versions or modified by the authors of the present study, were used in the research. The recording of the distribution of optical density of the information carrier around the object under analysis was carried out using a CCD matrix with the image acquisition card. The role of the information carrier in the experimental research was performed, alternatively, by the collimated beam of a 25 mW-power He-Ne laser or a slotted white light source in the form of a halogen lamp, type H3. The modifications introduced to the optical measuring range along with a reduction in the susceptibility of the systems to misalignment.
