This paper presents a smart beam profiling system capable of measuring the 3D spatial profile of laser and other collimated and non-collimated sources. The system utilizes an ESP32 camera module for portable imaging of laser beams and online computer program for collecting the images, processing and 3D plotting of the profiles. A customized smartphone app is developed for real-time monitoring the results and controlling the systems remotely thus allowing the system deployable into a large-scale profile measurements such as required for industry and hospital laser based diagnostic and surgery systems where precise and reliable profiles are maintained. The 3D profiles of a red laser diode and blue LED are characterized and beam diameter, divergence and propagation parameter are measured.
