Description
Y=sinωyt・・・(式1)
X=sin(ωxt+φ)・・・(式2)
ここで、φは垂直走査線Yに対する位相差であり、位相差φが無い場合(φ=0)には、図6(a)に示されるように、往路Ta(実線)と復路Tb(破線)とが均等に配置される描画軌跡(走査軌跡)を描く。なお、図6(a)は、垂直方向に1往復(1周期)する期間内に1フレームの描画を行うリサージュ走査の例示である。
共振周波数ωy:共振周波数ωx=1:水平走査線数・・・(式3)
以下、水平走査線数を20本、フレームレートを60fpsとした場合を例として、さらに説明する。なお、この例では、式3にしたがい、共振周波数ωy=30Hz、共振周波数ωx=600Hzとなる。
周波数比R=(1/N分周器を通過した水平位置センサの出力)/(垂直位置センサの出力)・・・(式4)
なお、標準状態では、位相差φ=0であり、周波数比R=1となっており、これが基準値となる。
