DISPOSITIF DE FOCALISATION D'ONDES ELECTROMAGNETIQUES |
摘要 |
<p>The electromagnetic wave focusing device has a mirror group consisting of a focal-line type primary reflective mirror and secondary reflective mirror which have a unique parabolic cross-sectional shape. Incident light rays are primarily reflected by the primary reflective mirror and are then secondarily reflected by the secondary reflective mirror, so that solar rays are focused at one point. The electromagnetic wave focusing device can be made extremely thin and light-weight, and can be folded without causing great loss of precision or great increase in mass. Consequently, the mirror bodies can be folded into a compact form and loaded inside the restricted space of a rocket or the like; thus, the device can be transported into aerospace, and a sunlight focusing device having high focusing performance can be reproduced on-site with a high precision.</p> |
