- Conservation of étendueWhat are your opinions on the conservation of étendue? I believe that multiple-exposed thick or volume (Bragg) holographic optical elements can be used to gain greater étendue than a classical lens system by combining more than one optical system in the same physical volume. What do you think?Like
