PROBLEM TO BE SOLVED: To provide a technique for preferably adjusting polarization between reference light and signal light in OCT measurement.SOLUTION: In an optical image measuring apparatus, the signal light transmitted through an object to be measured is superimposed on the reference light to generate coherent light, and an image of the object is formed based on the result of coherent light detection. The optical image measuring apparatus includes a detection unit, an adjustment unit, and a formation unit. The detection unit detects each of polarization states of the signal light and the reference light. The adjustment unit adjusts the polarization state of the signal light and/or the reference light based on the result of polarization state detection. The formation unit forms the image of the object based on the result of the coherent light detection which is obtained by superimposing the signal light and the reference light after adjustment of the polarization states of the lights.COPYRIGHT: (C)2013,JPO&INPIT【課題】OCT計測における参照光と信号光との間の偏光調整を好適に行うことが可能な技術を提供する。【解決手段】光画像計測装置は、被測定物体を経由した信号光を参照光に重畳させて干渉光を生成し、この干渉光の検出結果に基づいて被測定物体の画像を形成する。光画像計測装置は、検出部と、調整部と、形成部とを有する。検出部は、信号光及び参照光のそれぞれの偏光状態を検出する。調整部は、偏光状態の検出結果に基づいて、前記信号光及び/又は前記参照光の偏光状態を調整する。形成部は、偏光状態が調整された後の前記信号光と前記参照光とを重畳させて得られる干渉光の検出結果に基づいて、被測定物体の画像を形成する。【選択図】図3
