Digital measurement device for zero baseline movement of white light sight

Abstract

The invention relates to a digital measuring device for the zero position sight radius offset of a white-light sighting telescope, and belongs to the technical field of measurement for performance parameters of white-light sighting telescopes. The digital measuring device comprises a light source, ground glass, a reticle, a beam splitter prism, sheet glass I, sheet glass II, an angular displacement sensor I, an angular displacement sensor II, an objective lens, a fine turning mechanism, a single-chip microcomputer and an OLED display device. Compared with the prior art, the digital measuring device is utilized, the sheet glass is pushed by adjusting the fine tuning mechanism, a graduated image of the measuring device is superposed with the sighting telescope in a graduated mode, values measured by the angular displacement sensors before and after a change of the sight radius are recorded, the single-chip microcomputer reads the angular displacement data and perform corresponding conversion on the data, final data are displayed on an OLED display screen, the data displayed on the OLED display screen are coupled on a main optical path through the beam splitter prism, and the sight radius offset data on the OLED display screen can be directly observed by human eyes while tuning and alignment are performed.

Description

technical field [0001] The invention is used for measuring the aiming baseline variation of a white light sight, and belongs to the technical field of measuring performance parameters of a white light sight. Background technique [0002] The aiming device is an important part of light weapons. With the help of the scope, the weapon can be aimed at the target and shoot more accurately, without wasting bullets and losing combat opportunities. Aiming devices that use an optical sighting system are called optical sights, and those that are usually used during the day are called white light sights. As the aiming device for gun shooting, the white light sight can "zoom closer" to the target during shooting, so that the shooter can easily find the target; and it can greatly improve the aiming accuracy, and at the same time see the target and aiming marks clearly, making it easy to determine aim Whether the marker is on target. [0003] The so-called aiming baseline variation, tha...

Problems solved by technology

However, the old-fashioned zero position meter is to mechanically subdivide the linear displacement of the thimble to push the flat glass. The processing technology and assembly technology of the reading subdivision mechanism are relatively high, and this kind of reading does not reflect the actual corner of the flat glass. , but to subdivide the linear displacement of the thimble that pushes the flat glass. There is a principle error in itself, and the linear displacement is realized through the helical pair. When the helical pair moves in the opposite direction, there is a backlash, which seriously affects the reading accuracy; in addition, the previous The reading is very troublesome. It is necessary to sum the readings of the reticle, the main reticle and the auxiliary reticle to obtain the change of the aiming baseline we want, and the external reading is not conducive to the operator to observe
