Abstract

　本発明に係る計測装置（６０）は、平面状に並んだ複数の画素領域（２１）を有したイメージセンサー（２０）と、被検物（６２）の表面からの光を入射させてイメージセンサー上に被検物の表面の像を結像させる色出しレンズ（１１）と、イメージセンサーを構成する複数の画素のそれぞれが受光した光の強度に基づいて、被検物の表面の高さを算出して被検物の３次元形状を測定する演算処理部（３０）とを備えて構成されている。複数の画素は受光した光を少なくとも２つの波長毎に分けて波長毎の受光強度を検出し、演算処理部は複数の画素において検出された波長毎の受光強度のうち、２つの波長の受光強度から強度レベルの差を検出し、強度レベルの差を基に被検物の表面の垂直方向距離を測定して被検物の３次元形状を求める。
