Abstract
【選択図】図7
Description
軸(bi−axial)、二重アパーチャのトランシーバと称される。それは、レーザ2からのビーム4の光軸及びレシーバ・テレスコープ6のFOVの軸が独立していること、及びレーザビームと検知器とが同じアパーチャを共用していないからである。この構成では、トランスミッタ・ビームとレシーバのFOVが重ならない領域においてレシーバの前側に「盲点」(blind spot)14を作り出してしまう点で問題がある。この盲点14の長さが動作の最小レンジ(距離)を表わす。もし、照明ビーム4光軸及びテレスコープ6のFOVの軸が盲点14を短くして最小範囲を減少させるために互いに向かって傾斜する構成は望ましいが、そうするとレーザビームとFOBとがそれらの発散のためにもはや重ならない離間点のところで始まる新たな盲点(図示せず)を作り出すであろう。
(a)トランスミッタとレシーバのアパーチャを小さくすることにより両者の間隔を縮小すること(但し、これは究極的には回折により制約される)。
(b)トランスミッタとレシーバのアパーチャを食い違いにずらすこと、すなわち、トランスミッタのアパーチャを焦点のところに配置するとともに検知器のアパーチャをレンズ近傍に配置してその視野を増大させる。しかし、この解決方法は検知器によりレーザのアパーチャが影になることで制約される。
