Problems solved by technology

However, since most supplementary light systems have a fixed lighting angle of view, if you want to use a zoom lens to observe and monitor distant and near objects, it is easier to observe a specific distance field of view in a low-light environment, but supplementary light will appear if the distance is too close The angle of view is insufficient, and the field of view will be blurred if it is too far away

Abstract

The invention discloses a linked focusing apparatus used for optical equipment and a using method thereof. The apparatus comprises a host computer. The host computer is connected with an information processing module. The information processing module is connected with a focusing motor, a diaphragm motor, a zooming motor, a laser lens motor and a laser. A CAN communication module, a zoom lens AD sampling module connected with a zoom lens and a laser lens AD sampling module connected with a laser illumination lens are integrated inside a circuit control panel. The zoom lens is provided with a lens focusing gear, a diaphragm adjusting gear and a lens zooming gear. The laser illumination lens comprises the laser lens motor. The laser illumination lens further comprises an optical assembly for adjusting laser beam divergence angles, and a leading screw. Compared with the prior art, the apparatus has the characteristics of compact structure, low cost and high reliability. By adopting the zoom lens and the laser illumination lens for linked focusing, the apparatus makes clearest observation on far and near fields through a monitor easily achieved. The equipment utilization efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of optical equipment, in particular to a linkage focusing device for optical equipment and a method for using the same. Background technique [0002] CCD (Charge Coupled Device) can be used in a low-light environment with infrared LED light supplementary lighting to use simple day and night observation functions, and is widely used in the field of video surveillance. However, since most supplementary light systems have a fixed lighting angle of view, if you want to use a zoom lens to observe and monitor distant and near objects, it is easier to observe a specific distance field of view in a low-light environment, but supplementary light will appear if the distance is too close The viewing angle is not enough, and the field of view will be blurred if it is too far away. The linkage focusing device with zoom lens and laser lighting lens can be used very well at low cost, and can achieve adjustable field of vi...
