The research proposes a system for recording and processing the spatial characteristics of the laser beam to detect the thermal convective flow appearing already at an early stage of the fire. The work is carried out within the framework of the development of new effective methods and technical means of early fire detection. Methods of computer processing of spatial characteristics of a laser beam, allowing to detection of the appearance of a thermal convective flow, are investigated. The efficiency of the correlation method of processing spatial characteristics has been investigated. A processing method, reflecting a pixel-by-pixel difference of counts of the intensity distribution of the beam profile, is offered. Their efficiency has been compared.
