Description
EPO0524561A1は、遠隔制御車輌に搭載した高エネルギー放射線探査システムを記載している。これはオペレータ・ステーションから作動され、原子力発電所などの区域のリアルタイム・ビデオ像に重ねられる高解像度の線量マップを形成するために使用される。放射源をピンポイントで指示できるようにするために、このシステムは正確に定めた方向からの放射線を検出することができる。レンジ・ファインダー、ビデオ・カメラおよびレーザー・ポインターが放射線検出器と同じプラットフォーム上に取付けられている。それらは放射線検出器と同じ方向で指示するように整列されている。放射線検出器は放射源を発見すると、レーザー・ポインターは放射線検出器の視野のほぼ中央を表示するためにビデオ像上で見えるように意図した輝点を形成する。
