1. An electromagnetic wave detection apparatus comprising:
a first propagation unit comprising a plurality of pixels along a reference surface and configured to propagate electromagnetic waves incident on the reference surface in a particular direction at each of the pixels;
a second propagation unit including a first surface configured to propagate electromagnetic waves incident from a first direction in a second direction and propagate electromagnetic waves propagated in a third direction in a fourth direction, a second surface configured to separate electromagnetic waves propagated in the second direction and propagate the electromagnetic waves in the third direction and a fifth direction, a third surface configured to emit electromagnetic waves propagated in the fourth direction, a fourth surface configured to emit electromagnetic waves propagated in the fifth direction towards the reference surface and to propagate electromagnetic waves incident again from the reference surface in a sixth direction, a fifth surface configured to propagate electromagnetic waves propagated in the sixth direction in a seventh direction, and a sixth surface configured to emit electromagnetic waves propagated in the seventh direction;
a first detector configured to detect electromagnetic waves emitted from the third surface; and
a second detector configured to detect electromagnetic waves emitted from the sixth surface.
