Dispositivo opto-electrónico y métodos para colimar y determinar el grado de colimación de un haz de luz

摘要

The invention relates to an optoelectronic device for determining the degree of collimation of a light beam, which can also be used for collimating beams by means of the incorporation of a collimation element (2). The device comprises a diffraction grating (3), a mask (5) including a plurality of windows (4) each having a diffraction grating, said diffraction gratings of the windows (4) being out of phase with one another, a matrix (7) of photodetectors (8), the number of which can be greater than or equal to the number of windows (4) of the mask (5) or which can be located in a matrix with two-dimensional distribution (CMOS or CCD), and one or more data processing elements (8). The invention also relates to methods for determining the degree of collimation of a light beam or for collimating a beam.
