OPTICAL-ELECTRONIC CONVERTER FOR NON-CONTACT MEASUREMENT OF OBJECTS DISPLACEMENTS RELATIVELY TO ONE ANOTHER Russian patent published in 2005 - IPC

FIELD: optics.

SUBSTANCE: device has radiation source in form of light diode, mounted on one of objects, and multi-element linear photo detector, mounted on another object. Photo detector is made in form of two pairs of multi-element linear photo detectors distanced from each other, light-sensitive lines of which in each pair are mounted at angle α₁, relatively to other pair, and between light diode and each pair of linear photo detectors objective and device are mounted, the latter being used for forming light mark image from light diode in form of cross in plane of each pair of linear photo-detectors, made in form of no less than two cylindrical lens bitmaps, not screening each other, angle between symmetry planes of which is α₂.

EFFECT: higher precision.
