Abstract

Un aparato para visualizar una imagen suspendida en el espacio que comprende: un objeto (10) para visualizar; unos medios reflectantes que están dispuestos para recibir luz de un objeto, en que los mencionados medios reflectantes comprenden bien una superficie especularmente reflectantes o un primer retro-reflector (12), en que el primer retro-reflector comprende un conjunto de elementos retro-reflectantes o una lámina retro-reflectante; un divisor del haz (14) en un recorrido (16) de la luz procedente del objeto hasta el primer retro-reflector, estando el divisor del haz (14) dispuesto en un ángulo agudo con la dirección de propagación de la luz, de forma que transmita parte de la luz y refleje parte de la luz, en que la luz que es transmitida o reflejada por el divisor del haz (14) es recibida por el primer retro-reflector (12), siendo reflejada por su parte posterior hacia el divisor del haz, el cual o bien reflejao transmite parte de esta luz retro-reflejada, para formar una imagen real (18) suspendida en el espacio; un elemento óptico convergente (20) dispuesto entre el divisor del haz (14) y el primer retro-reflector (12), de forma tal que durante la utilización la luz procedente del divisor del haz (14) pasa a través del elemento óptico convergente (20) hacia el primer retro-reflector (12), el cual la refleja de vuelta a través del elemento óptico (20) hacia el divisor del haz (14), caracterizado porque el elemento óptico convergente (20) comprende una lente Fresnel que tiene una superficie substancialmente plana o uniforme y una superficie con surcos, en que la configuración de los surcos de la superficie con surcos no tiene un punto de simetría central.
