Description
◎距離と受光量和の相関値γ(L)=距離(LT)/受光量和(Pbt+Pct)
◎角度と受光量比の相関値γ(θ)=角度(θT)/受光量比(Pbt/Pct)
◎LS=γ(L)×(Pbs+Pcs)
◎θS=γ(θ)×(Pbs/Pcs)
X成分:Δθ=(θc−θb)=γ(θ)×{(Pbc/Pcc)−(Pbb/Pcb)}
Y成分:ΔL=(Lc−Lb)=γ(L)×{(Pbc+Pcc)−(Pbb+Pcb)}

Claims (4)
- 略扇状の照射範囲を有し、この照射範囲をもって操作範囲とし、光学部品を有する1つの発光素子と、前記発光素子からの照射範囲と受光範囲を重ね、光学部品を有する2つの受光素子とからなり、前記照射範囲内に挿入された所定の物体からの反射光により前記物体の移動、若しくは、位置検出を行う二次元位置検出装置であって、前記発光素子及び前記2つの受光素子は略同一方向を向くように配置され、前記受光素子の少なくとも一方には、前記発光素子を中心とする略扇状とした前記照射範囲に対しての放射角方向への感度に他方の受光素子の方向へ向かうに従い受光感度が順次増加又は減少する受光感度特性を光学部品によりもたせ、他方の受光素子の受光感度特性との演算により、前記照射範囲内での前記発光素子からの遠近方向への移動量、および、これと直交する方向への移動量の二次元方向の移動、若しくは、位置検出を可能とすることを特徴とする二次元位置検出装置。
- 前記操作範囲内の適宜の位置には基準点が設定され、この基準点に前記所定の物体を挿入することで反射率を測定し、前記発光素子の明るさ、若しくは、受光素子の感度の少なくとも一方を調整して前記受光素子に達する反射光の光量を一定化するキャリブレーション機能を有することを特徴とする請求項1記載の二次元位置検出装置。
- 前記操作範囲内に最初に挿入される前記所定の物体の位置により前記発光素子に印加される駆動電流は可変とされ、前記所定の物体が最初に挿入されたときの距離が前記発光素子から離れるに従い前記駆動電流は大きく設定される構成とされて前記操作範囲が大きく設定され、前記発光素子から近づくに従い前記発光素子に印加される駆動電流は小さく設定されて前記操作範囲が狭く設定されることを特徴とする請求項1または請求項2記載の二次元位置検出装置。
- 前記発光素子により形成される前記操作範囲は任意波長の光線であり、且つ、操作方向と直角方向には薄面として形成されていることを特徴とする請求項1〜請求項3記載の二次元位置検出装置。
