Influence of Angle of View on Temperature Measurements Using Thermovision Camera

The influence of the angle of view on the reliability of temperature measurements using thermovision cameras was studied. The experimental setup consisted of a camera and infrared radiator, which allows for temperature adjustment and changes in the angle of view. The experiments were conducted in the laboratory. Preselected distance intervals between the camera and radiator were observed. Three thermovision cameras were used in the measurements. The critical value for the angle of view was determined.
