ELECTROMAGNETIC NONCONTACTING MEASURING APPARATUS |
摘要 |
<p>ELECTROMAGNETIC NONCONTACTING MEASURING APPARATUS A noncontacting apparatus and method for following the changes in impedance of a substance located within a specified investigation zone. A bidirectionally focused electromagnetic beam, having a pair of foci, is aimed with one of its foci located adjacent such a zone. A receiver located adjacent the other one of its foci is monitored for electrical changes therein, and such changes are interpreted as indications of impedance changes in the selected zone.</p> |
