Laser Beam Analysis Using Image Processing

The laser beam profiles captured by CCD camera processed and analyzed by using 2D- graphic and displayed on the monitor. The analysis of the He-Ne profiles and laser diode profiles are presented. The results showed that the He-Ne laser emits a pure Gaussian beam, whereas the diode laser emits an elliptical beam shape. The laser beam profile analysis developed to study the intensity distribution, the laser power, number of modes and the laser beam, these parameters are quite important in many applications such as the medical, industrial and military. The analysis of the image profile can be used in determination the distance of the objects depending on the distribution of the spot contours of the laser beam with its width. As well as it can be used to capturing images to the objects and determining their distance and the shape of the objects.
