These are things I've found on the Internet. Look upon my works ye mighty and despair.
Catching Elephant is a theme by Andy Taylor
Conventionally, a half mirror or polarization beam splitter was used as a combiner that superimposes a display image and an external image. However, it had a large optical loss ratio and a good see-through function could not be achieved. With efficient optical superimposition using an HOE, the high see-through characteristic that seldom loses external light and bright image display can be achieved together.
