Description
θ=90−arccos{r/R}+n2/n1*sin{arcos{r/R}−arctan{(d−(R−(R2−r2)1/2))/r}}
ここで、rはレンズのアパーチャ半径、Rはレンズ578の曲率半径、n2は筐体172内の材料の屈折率、n1は筐体172の外の屈折率、dはレンズ578の中心から露光変換器178までの距離であり、更にθは度単位で測定される。通常、T−1・(3/4)筐体172は、エポキシで充填されており、センサ回路15は、n1に対するn2の比をおよそ1.5とする空気中で動作する。曲線590は、半径Rが5.0mmの球面レンズ578を有するT−1・(3/4)筐体の距離dの関数として半角の視野θをプロットする。光変換器178がレンズ578から遠くに移動するにつれて、視野は減少する。
G=f2/(f−d)2
y(n)=x(n)/64+63y(n−1)/64
ここでx(n)は、積算時間期間に対して正確にスケーリングされた直前に取得された周囲光信号2060の2進対数近似値、y(n−1)は前のフィルタ出力、y(n)は現在のフィルタ出力とする。アナログ光信号で平均対数を用いることについては、Jon H.Bechtelに付与された「CONTROL SYSTEM FOR AUTOMOTIVE REARVIEW MIRRORS(自動車用リアビューミラーの制御システム)」という名称の米国特許第5,204,778号に記載されている。
TG(n)=antilog2(K1−y(n))−K2
ここで、TG(n)はサンプル時間nにおけるフィルタ出力に対するグレアセンサ50bの積算時間期間、K1は乗算定数、K2は加算定数である。定数K1及びK2は経験的に求められる。周囲光信号2060の対数平均が、一定のレベルを下回る場合、最大グレア感度積算時間期間を用いる。
50 センサ装置
61 屈折レンズ
112、113 光線
