MONITORING METHOD AND DEVICE USING SHADOW DEFECTOSCOPY Russian patent published in 2009 - IPC G01N21/952 

FIELD: physics; measurement.

SUBSTANCE: proposed monitoring device contains a support arm unit, light emitter, light receiver for receiving light emitted by the source. The device also contains a bar with two opposite ends on which are fitted the source and receiver, and a double regulated hinge, by which the bar is attached to the support arm. The double hinge has two axes of rotation (y, z), perpendicular to each other and to the main path (x) of light between the emitter and the receiver. The bar is arched between the ends. The emitter and the receiver are equipped with devices for angular transmission of light and are parallel each other and perpendicular to the main path of light. The method of monitoring the section, realised using the method, involves fitting the device such that, the main path (x) of light is at a tangent to the monitored section, and the bar can be adjusted in this direction through adjustment of the double hinge.

EFFECT: wider field of vision due to panoramic rotation of the axis of sight, increased resolution and range of operation of the device.
