Weight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)

The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...

A new optical method for studying flames

2014 A spatial-filtering set-up is used in order to visualize mean turbulences in a flame. REVUE DE PHYSIQUE APPLIQUÉE TOME 8, JUIN 1973, PAGE , Classification Physics Abstracts 04.00 08.50 Flames are not easy to photograph. But, by their temperature and concentration gradients they may be considered as phase objects and are subject to several optical treatments [1]. In one of them, a source of...

Using Trusted Sensors to Monitor Patients' Habits

Patients are notoriously inconsistent with taking their medications. Doctors and insurance companies have an incentive to monitor and collect data on whether medical patients and insurance customers are following prescriptions and maintaining a healthy lifestyle. A convenient way of gathering such data is using smartphones. For example, accelerometer readings can be used to reveal how physicall...
