Description

Double-sided optical alignment device The present invention relates to a double-sided optical alignment device, and more specifically, to a double-sided optical alignment device designed with a horizontal multilayer (double-sided) structure to effectively transmit output laser energy and thereby minimize the optical path. A laser weapon system is a weapon designed to neutralize enemy unmanned aerial vehicles (UAVs) or drones by intercepting them with a high-power laser. The optical alignment device, which is the core of this weapon system, consists of a camera, lens, and mirror; it is a device that aligns the high-power laser generated by the laser generator with the targeting reticle and maintains this alignment for the duration of the firing. Conventional optical alignment devices with a vertical single-layer structure occupy unnecessary space as the optical elements are arranged vertically within a single layer, which in turn increases the overall size and weight of the laser weapon system. In addition, the vertically arranged optical elements present significant difficulties in maintaining the optical axis, which has the disadvantage of making the system more complex. FIG. 1 is an example view of the exterior of a double-sided optical alignment device according to the present invention. FIGS. 2(a) and 2(b) are exemplary diagrams showing the lower and upper portions, respectively, of an intermediate panel containing an optical element of a double-sided optical alignment device according to the present invention. FIG. 3 is an exemplary diagram showing the side view of an intermediate panel containing an optical element of a double-sided optical alignment device according to the present invention. FIGS. 4(a) and 4(b) are exemplary diagrams showing the lower and upper parts, respectively, of an intermediate panel from which an optical element of a double-sided optical alignment device according to the present invention has been removed.
