Description
前記z方向補正手段は、前記細胞伸展装置(伸展性部材)又は前記顕微鏡をz方向に前記所定周期Tで振動させる。
図1、図2に示すように、本発明の一実施の形態に係る細胞観察装置10は、細胞伸展装置11、顕微鏡12、x方向移動装置13(x方向補正手段の一例)、及びz方向移動装置14(z方向補正手段の一例)を備える。
(2)x方向移動装置を稼動させ、x方向(伸展方向)のみのキャンセリング(補正)を行った場合の画像を図5(a)〜(c)に示す。このとき、細胞伸展装置の2.00mmの移動(振幅)に対し、1.117mmの移動(振幅)で逆位相で振動させた。画像から、模擬細胞の位置が大きくずれることはないが、焦点位置がずれてしまうため鮮明な画像が得られないことが確認された(図5(b)参照)。
(3)前記のx方向移動装置の稼動に加え、z方向移動装置を稼動させ、x方向及びz方向のキャンセリングを行った場合の画像を図6(a)〜(c)に示す。このとき、z方向移動装置は、36.5μmの振幅で振動させた。画像から、伸展の途中も模擬細胞の様子が明確に観察できることが確認できる。
