Abstract

The focus of this paper is to describe the development and fabrication of a portable hand-held electronic area planimeter to measure wheal areas during dermatitis assays. The planimeter straddles over the wheal and the scientist traces the wheal's perimeter using an optical beam splitter/cross-hair and a miniature x-y table. Transducers connected to the x-y table and an electronic circuit performs the area integration and displays the data on a digital panel meter. The apparatus permits noncontact measurement of areas up to 1000 mm2 with a resolution of 1 mm2.

摘要

本文的重点是描述一种便携式手持电子面积测量仪的开发与制造，用于在皮炎检测中测量风团面积。该测量仪横跨在风团上，科学家使用光束分离器/十字准线和微型xy工作台追踪风团的周长。连接到xy工作台的传感器和一个电子电路进行面积积分，并在数字面板仪表上显示数据。该仪器允许对面积达1000平方毫米的区域进行非接触式测量，分辨率为1平方毫米。
