Abstract

A method of calibrating photodiode measurements of cell motion is described. A transparent glass plane is inserted perpendicular to the light path, in front of the photodiode. When the glass plane is rotated, changing the angle between the plane and the light path, the image is displaced. The rotatable glass plane acts as an optical lever to simulate cell motion. The optical lever is easy to construct and offers excellent linearity and accuracy.

摘要

描述了一种校准光电二极管对细胞运动测量的方法。在光电二极管前方，插入一块垂直于光路的透明玻璃平面。当玻璃平面旋转时，改变平面与光路之间的角度，图像就会发生位移。可旋转的玻璃平面充当光学杠杆来模拟细胞运动。该光学杠杆易于构建，并且具有出色的线性度和精度。
