total reflected air layer mechanism (G) within the transparent pyramid. The arrises
(6, 7, 8, 9, 8', 7') of the transparent pyramid and the boundary of the
total reflected air layer mechanism are collinear. When a vertex of the pyramid
is considered as the visual eliminating point (5) of the pyramid arrises, the
boundary of the total reflected air layer mechanism will be overlapped with the
pyramid arrises completely in vision, and the boundary of the total reflected air
layer mechanism will be a part of the pyramid in vision and can not be distinguished in
vision, so the total reflected air layer mechanism will be hided in the device without
