Abstract

　瞳孔測定装置１は、視標１０と、赤外光源１２Ｌ，１２Ｒと、光路Ｌ１，Ｌ２に挿脱自在に設けられた遮蔽板１３Ｌ，１３Ｒと、レンズ１４Ｌ，１４Ｒと、両眼からの角膜反射光をそれぞれ撮像するカメラ１８Ｌ，１８Ｒと、瞳孔解析装置２１とを備える。瞳孔解析装置２１は、輻輳量算出部と、注視判定部とを備え、注視判定部は、遮蔽板１３Ｒにより遮蔽されていない被検眼ＥＬの瞳孔直径の変化率に基づき被検眼ＥＬが計測時に視標１０へ指向されているかを判定する。また、輻輳算出部は、遮蔽板１３Ｒにより遮蔽されている被検眼ＥＲの瞳孔位置の変化に基づき被検眼ＥＲの輻輳量を算出する。これにより、測定結果の信頼性の向上を可能にした瞳孔測定装置が実現される。
