OPTICAL GAS DETECTOR |
| 摘要 |
A gas detector including a planar mirror; a concave spherical mirror facing the planar mirror, having an optical axis orthogonal to the planar mirror, the distance between the planar and spherical being equal to 0.75 times the radius of curvature of the spherical mirror, to within 10%; a radiation emitter/receiver arranged at the point of intersection of the spherical mirror and of the optical axis; and a radiation receiver/emitter arranged at the point of intersection of the planar mirror and of the optical axis. |

1. A gas detector comprising:
a planar mirror (2); a concave spherical mirror (4) facing the planar mirror (2), having an optical axis (6) orthogonal to the planar mirror, the distance (D) between the planar and spherical mirrors being equal to 0.75 times the radius of curvature of the spherical mirror, to within 10%; a radiation emitter/receiver (E) arranged at the point of intersection of the spherical mirror (4) and of the optical axis (6); and a radiation receiver/emitter (R) arranged at the point of intersection of the planar mirror (2) and of the optical axis (6). |
