A simple and inexpensive instrument called a longitudimeter for measuring distances in microscopy was constructed from a precision map-measuring device and an electric lamp positioned eccentrically on a stand. A precision better than 1% was readily obtained in measurements of the perimeters of trabecular surfaces in cancellous bone. Mixed-image longitudimetry was devised for length measurements in cancellous bone, but the method seems suitable for a wider application in quantitative microscopy.
一种名为长度测量仪的简单且廉价的用于在显微镜下测量距离的仪器,是由一个精密地图测量装置和一盏偏心放置在支架上的电灯构建而成。在测量松质骨小梁表面周长时,很容易获得优于1%的精度。为松质骨长度测量设计了混合图像长度测量法,但该方法似乎适用于定量显微镜更广泛的应用。
