Synopsis : On-line measurement of quality and dimensions of products and the condition of processes has recently become very important to keep stable production of high quality and homogeneous products. This tendency is also applicable to the steel industry. To satisfy these strong needs, optical measurement technologies and instruments have been developed because of their advantages such as noncontact, high-response and high-sensitive measurements. Recent advances of hard-ware technologies have also contributed to development of new instruments. Recent examples are dimensional measurement using optical cross sectional method and surface property measurement of steel sheets or rolls for which surface reflective characteristics and image information are utilized. In order to develop these kinds of instruments, durability against adverse environment, countermeasures to realize high response, resolution and precision measurement are taken into consideration. In this paper, the actual state of optical measurement technologies and also future trends are described. |
