Abstract

Sensor de suciedad y procedimiento para detectar la cantidad de suciedad de una superficie. Un sensor (20) para detectar la cantidad de suciedad de una superficie, que comprende: una superficie transparente (21) expuesta a suciedad; un emisor de luz (22) para emitir un haz de hacia la superficie transparente; un primer receptor de luz (23) y un segundo receptor de luz (25); medios (24) entre el emisor de luz (22) y la superficie transparente (21) configurados para dejar pasar una parte de la luz procedente del emisor hacia la superficie transparente (21) y para redireccionar el resto de luz hacia el segundo receptor (25); medios de adquisición y procesamiento (26). El primer receptor de luz (23) está configurado para recibir la luz difundida al chocar contra la suciedad de la cara externa (21e) de la superficie transparente (21). Los medios de adquisición y procesamiento (26) están configurados para calcular una medida porcentual del grado de suciedad de dicha superficie transparente (21).
