で一体的に並置きれた２分割レンズと、前記拡散反射面
から見て上記２分割レンズの背面に配置されこの２分割
レンズをそれぞｔｔｉ、 る前記拡散反射面からの反射
晃を受けその幅寸法を電算的に測定するフォトダイオー
ドアレイとを備えたことを特徴、とする長さ測定装置。a projector that projects slit light onto a diffuse reflection surface; a two-split lens that directs the slit light toward the diffuse reflection surface and is integrally arranged side by side with a constant optical axis interval; and a photodiode array disposed on the back surface of the two-split lens, each of which receives light reflected from the diffuse reflection surface and calculates the width dimension of the two-split lens. Length measuring device.
