| 成果简介 | NOVELTY - The full-size spectacle gauge has a transparent insert (2) in the light opening (3) of the spectacle frame, on which two vertical parallel marks (4,5) are applied at a distance from each other determined by the ratio of the distance from the eye to the surface of the transparent insert on which the marks are applied. USE - Full-size spectacle gauge used in forest management, forest taxation, allocation of felling areas, and selective cutting to determine total cross-sectional area of trunks on one hectare of forest stand. ADVANTAGE - The achievement of the declared technical result is ensured, and consists in freeing the hands of the worker using it during measurements, and leads to increased ease of use. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the full-size spectacle gauge. 1Spectacle frame 2Transparent insert 3Light opening 4,5Vertical parallel marks |
