PROBLEM TO BE SOLVED: To provide an optical measuring apparatus for an eyeball, etc. with improved measurement accuracy in optical measurement as compared with a case where correction by a signal in a non-emission period is not made.SOLUTION: An optical measurement apparatus 1 includes: a light emission part 20A for emitting a light to an eyeball 10 of a person to be measured a control part 70 for controlling the light emission part 20A so that a cycle of an emission period in which a light is emitted and a non-emission period in which a light is not emitted is shorter than a cycle of fluctuation mixed in a measurement environment a light receiving part 20B for receiving a light from the eyeball in the emission period and outputting a first signal in the emission period, and outputting a second signal in the non-emission period and a correction part 40 for correcting the first signal using the second signal input from the light receiving part 20B.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】非出射期間における信号による補正をしない場合に比べて、光計測における計測精度を向上させた眼球の光計測装置などを提供する。【解決手段】光計測装置1は、被計測者の眼球10に向けて光を出射する光出射部20Aと、光を出射する出射期間と光を出射しない非出射期間との周期が計測環境において混入する揺らぎの周期より短くなるように光出射部20Aを制御する制御部70と、出射期間において眼球から受光して第1の信号を出力し、非出射期間において第2の信号を出力する受光部20Bと、受光部20Bから入力された、第2の信号を用いて第1の信号を補正する補正部40とを備える。【選択図】図1
