Patent ID: 11874162

Abstract:
An electromagnetic wave detection apparatus 10 includes a first propagation unit 16, a second propagation unit 17, a first detector 19, and a second detector 20. The first propagation unit 16 propagates electromagnetic waves incident on a reference surface ss in a particular direction using each pixel px. The second propagation unit 17 includes a first surface s1, a second surface s2, a third surface s3, a fourth surface s4, a fifth surface s5, and a sixth surface s6. The first surface s1 propagates electromagnetic waves incident from a first direction in a second direction and propagates electromagnetic propagated in a third direction in a fourth direction. The second surface s2 separates electromagnetic waves propagated in the second direction d2 and propagate electromagnetic waves in a third direction d3 and a fifth direction d5. The first detector 19 detects electromagnetic waves emitted from the third surface s3. The second detector 20 detects electromagnetic waves emitted from the sixth surface s6.
