Abstract
Un radar laser que comprende: un láser (10): usado para emitir un haz de luz laser; un detector (20): usado para recibir el haz de luz laser reflejado; y un conjunto de estructuras transceptoras (30): usadas para recibir el haz de luz laser emitido a lo largo de una dirección preestablecida y que transportan el haz de luz laser al detector (20), las estructuras transceptoras (30) se disponen de forma coaxial con el laser (10), las estructuras transceptoras (30) comprenden una unidad de ajuste de campo de vision vertical, la unidad de ajuste de campo de vision vertical haciendo que el haz de luz laser tenga una distribucion no uniforme en el rango del campo de vision vertical y/o ajustando el rango de campo de visión vertical del haz de luz laser. El radar laser tiene una estructura simple y es conveniente para ensamblar y, cuando esta en uso, puede hacer de manera mas flexible ajustes para un detector blanco (40) a traves del laser (10) y la unidad de ajuste de campo de vision vertical, con lo que se evitan las perdidas de forma efectiva.
