The paper proposes a method to study functional disorders of hollow tubular organs using an infrared optoelectronic system that functions on the principle of optical location. The paper provides a general design of the developed optical probes used in gastroenterology, proctology, pulmonology and urology. The diagnostic results of the study of functional esophageal disorders are demonstrated through the example of the trachea and bronchi. The results are visualized on the monitor as an amplitude diagram that depends on the speed and frequency of changes in the lumen of the examined organ. The analysis of the diagrams provides information on functioning and mobility of the walls of the examined organ. The study results are recorded and stored for subsequent analytical processing of information.
