Title:
ELECTROMAGNETIC WAVE DETECTION DEVICE AND INFORMATION ACQUISITION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/220974
Kind Code:
A1
Abstract:
This electromagnetic wave detection device 10 comprises a first propagation unit 16, a second propagation unit 17, a first detection unit 19 and a second detection unit 20. The first propagation unit 16 allows electromagnetic waves incident on a reference surface ss to travel in a prescribed direction for each pixel px. The second propagation unit 17 comprises 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 second surface s2 separates electromagnetic waves travelling in a second direction d2, causing these to travel in a third direction d3 and a fourth direction d4. The fourth surface s4 emits electromagnetic waves travelling in the fourth direction d4 onto the reference surface ss, and allows electromagnetic waves re-incident from the reference surface ss to travel in a fifth direction d5. The first detection unit 19 detects electromagnetic waves emitted from the third surface s3. The second detection unit 20 detects electromagnetic waves emitted from the sixth surface s6.
