Summary:Methods and optoelectronic devices to collimate and/or determine the degree of collimation of a beam of light. The invention relates to a method for determining the degree of collimation of a light beam and to a method for collimating a light beam by calculating the periods of two or more autoimages generated by a diffraction grating at different distances. In addition, it includes optoelectronic devices designed to carry out both methods. The different devices comprise a diffraction network (3), one or more photodetection systems (4) and an electronic data processing device (5). When a single photodetection system is included, two or more autoimages are obtained by means of mirrors or by tilting the photodetection system with respect to the optical axis of the device. Devices designed to collimate a beam include a collimator element (2).

La invención se refiere a un método para determinar el grado de colimación de un haz de luz y a un método para colimar un haz de luz mediante el cálculo de los periodos de dos autoimágenes, o más, generadas por una red de difracción a distancias diferentes. Además, incluye dispositivos optoelectrónicos diseñados para llevar a cabo ambos métodos. Los distintos dispositivos comprenden una red de difracción (3), uno o varios sistemas de fotodetección (4) y un dispositivo electrónico de procesamiento de datos (5). Cuando se incluye un único sistema de fotodetección, se obtienen dos o más autoimágenes mediante espejos o mediante la inclinación del sistema de fotodetección con respecto al eje óptico del dispositivo. Los dispositivos diseñados para colimar un haz incluyen un elemento colimador (2).
