Abstract

The algorithms developed can be used for any application, which requires tridimensional visualization and additional processing of experimentally acquired images. This paper especially refers to image processing and visualization in laser beam analysis. The information, acquired by a CCD camera and stored as a matrix of gray levels, is processed and the result is a 3-D representation of the beam intensity profile. An interpolation-and-averaging method (independent of the matrix dimensions) was developed, aiming at reducing the time required for data representation in on-line applications and also to diminish the camera noise and sampling errors. The experimental works were performed using a COHU 4913 camera, connected to an LBA-100 laser beam analyzer, which were coupled to a PC compatible computer. Several lasers, such as He-Nw, He-Se, pulsed and cw Nd:YAG lasers, laser diodes, and laser diode arrays, operating at different wavelengths, were studied. The developed algorithm was implanted on the computer, so that the overall system performances were improved, obtaining a user-friendly interface for data visualization and further processing.
