Measurement of gradient index profiles by Babinet fringe analysis.
A theory for determining one-dimensional ray deflections with the help of distorted Babinet fringes has been developed. An approach for investigating two-dimensional ray deflections has been presented. Applications of the techniques for the study of gradient index glass have been described.
Accurate Adjustment of the Wedges of a Babinet Compensator
The appearance of a fringe system instead of complete darkness when a Babinet compensator is placed in zero azimuth between crossed Nicols indicates that the optic axes in the wedges are not accurately at right angles. A general theoretical analysis of the formation of this fringe system is given. Since, in practice, accurately crossed Nicols are seldom obtained, the analysis is extended to include the case where the angle between the vibration directions of the Nicols differs slightly from ½π. Curves are plotted showing the theoretical intensity distribution across the field of view for several selected cases and photographs of actual fringes are shown for comparison. Brief details are given of the use of the fringes to test the wedges before and after they are mounted as a completed compensator.
Complex telemonitoring of patients and elderly people for telemedical and homecare services
The paper presents a project that has as main goal researches, design and implementation of an electronic-informatics-telecom and scalable system, that allows the automatic and complex telemonitoring, everywhere and every time (at home, in hospitals, at work, of mobile subject etc, using several communication paths), in real time, of persons with chronic illnesses, of elderly people, of those having high medical risk and of those with neurolocomotor disabilities.
