Description

Technical Field

[0001] The invention relates to the field of optoelectronic sights, and in particular to a day and night fire control sight. Background Art

[0002] At present, for large-angle equipment with a firing angle greater than 20° and an effective distance greater than 1000m, the horizontal field of view angle of the equipped optoelectronic sight is generally not greater than 8°, and the vertical field of view angle is not greater than 6°, so it is impossible to meet the system's full field of view internally installed shooting table; for this reason, most optoelectronic sights use external mounting mechanisms for table installation, such as segmented table installation or mechanical line table installation, etc., and the above-mentioned table installation methods are generally low in accuracy and complex in structure, and cannot meet the requirements of high-precision rapid shooting; and the existing external mounting mechanisms do not have the function of vibration reduction and buffering, making optoelectronic sights with a large number of electronic components extremely easy to damage under high impact loads. Secondly, due to the long observation distance, the size of the installed optical lens is generally large. Affected by its weight and volume, the sight function is relatively single, such as the use of infrared mirrors or television mirrors, which leads to a system being equipped with more sights, which brings inconvenience to carrying and use. In addition, due to the long observation distance, factors such as wind, temperature, air pressure and drift also have a greater impact on shooting accuracy. Therefore, it is particularly important to develop a high-precision long-range optoelectronic sight for use in large-angle equipment to improve system performance. Summary of the invention
