Embodiment Construction
[0027] Referring to the accompanying drawings, an optical adjustment plate, which includes a carrier 1 that is sequentially provided with a transparent optical plate A, a diffuser plate B, a light guide plate C, a reflective plate D and a light source E, is covered with a matrix grid 2, and the inside of the grid 2 Equipped with symbols 3 arranged longitudinally from small to large or from large to small, the center of the grid 2 is provided with a scale 4 in the longitudinal direction via the connecting body, and the center of the grid 2 is provided with a color block 5 horizontally, and the color of the color block 5 changes gradually in parallel of.
[0028] As shown in the drawings, in order to distinguish the distance between the symbols 3 and the color blocks 5 in the grid 2 at the center of the grid 2 and the position of the scale 4, and to achieve a better rapid adjustment effect, the coding of the symbols 3 in the grid 2 The basic form of sequential arrangement and co...

An optical adjustment plate, which includes a carrier with a transparent optical plate, a diffuser plate, a light guide plate, a reflective plate and a light source in sequence, and a matrix grid is arranged on the carrier. Arranged symbols, the center of the grid is longitudinally set with a scale through the connecting body, and the center of the grid is horizontally set with color blocks, and the color depth of the color blocks changes gradually in parallel; it is used on a carrier equipped with light sources and other components. The technical solution of symbols, rulers, and color blocks overcomes the existing measurement methods of Young's modulus and linear expansion coefficient commonly used in "optical measurement experiments", which leads to the inability to quickly adjust the experimental measurement device and wastes a lot of time and delays It eliminates the shortcomings of the timely completion of experiments and engineering measurements; it is suitable for the use of various optical levers and telescopes in the traditional measurement of Young's modulus and linear expansion coefficient, and the use of night and dark environments.
Description
technical field [0001] The invention relates to a device for fast optical adjustment of the optical path, in particular to an optical adjustment plate that expands the field of view of optical levers and telescopes. Background technique [0002] At present, Young’s modulus and linear expansion coefficient measurement methods are often used in optical measurement experiments. This measurement method uses optical levers, telescopes and scales to form experimental measurement devices. Before optical measurement experiments, the optical lever and telescope must be aligned. Adjust, when people's eyes pass through the telescope, they can find a clear image at the scale in the plane reflector of the light lever. However, in the actual instrument adjustment, it is difficult to quickly find the image of the scale in the plane reflector of the optical lever, and it is impossible to quickly adjust the experimental measurement device, which makes the measurer waste a lot of time in the ...
