That is, the target optical device is a core aiming device of a precision guided weapon that detects a ground target on an aircraft, performs precise aiming and fires a laser so that a laser guided bomb can accurately hit the target. Aircraft air combat systems are generally composed of a mission control system, a sensor communication system, a survival system, and an armed system to provide functions to perform air-to-air, air-to-ground, and military missions. The pilot must determine the tactical situation from the sensor communication system mounted on the aircraft, external information sources such as the control center, the control center, the reconnaissance aircraft, the control unit, the satellite, and perform missions on the threat or target while detecting, capturing and tracking the target. The device for which the aircraft is to be mounted in order to perform these tasks is the optical device for the target. Such an optical device for a target is currently implemented in various forms. For example, Korean Patent Laid-Open Publication No. 10-2012-0096941 discloses a high-precision distance measuring apparatus.

The target optical device is composed of a daytime camera module, an infrared camera module, a laser module, and an optical system. In order to transmit light, which is a core function of an optical device for a target, and to receive light scattered in a target, Configuration is required. Particularly in the case of components used in aviation equipment, compactness and light weight are very important items. In order to realize this, a common optical system using one optical system in common is proposed, and a recently developed optical system for a target adopts a common optical system because of the tendency to be small and lightweight. The common optical system is mounted on the front side of the optical device for the target, and each module shares a common optical system to perform each task. The common optical system can be reduced in size and weight as compared with the targeting apparatus in which the multiple sensors are arranged, and has excellent optical performance. In addition, it is possible to arrange the sensor system and the optical system efficiently.

On the other hand, when the optical device for the target is operated in the daytime, the sunlight can be incident into the device through the optical window of the target optical device. The incident sunlight acts as a noise of information obtained in the process of oscillating the laser from the target optical device and collecting scattered light in the target. Therefore, there is a demand for an optical device for a target that can control the amount of sunlight incident and the amount of sunlight entering and passing through the optical window to increase the precision of information obtained from the target optical device.

Hereinafter, with reference to Figs. 1 to 5, a description will be given of an optical device 1000 for a sunlight cutoff according to an embodiment of the present invention. A target optical device 1000 for blocking sunlight includes a pod 100 having an internal space and a predetermined length extending in the longitudinal direction of the target 100. The optical device 1000 is installed inside the fad 100 and generates laser light, An optical module 200 disposed inside the fad 100 for receiving the laser light generated from the optical module 200 and outputting the laser light to the target, An optical window 400a mounted on one end of the fad 100 in the longitudinal direction of the fad 100 and an optical window 400a passing through the optical window 400a to enter the inside of the fad 100, A blind 520 disposed inside the optical window 400a so as to control the amount of sunlight to be irradiated and a blind 520 placed inside the optical window 400a so as to raise and lower the blind 520 in the height direction of the optical window 400a And a rail portion 510.

Specifically, the laser light generated by the optical module 200 is received, processed and expanded to be output. Further, the lens assembly 300 collects the light and the laser light reflected and received by the target, and provides the collected light to the optical module 200. To this end, the lens assembly 300 is formed of a combination of a plurality of convex lenses and concave lenses to adjust the spherical aberration. The lens assembly 300 performs the function of optically relaying the light energy and maintains the laser energy focus over temperature and altitude by translating the lens set.

The lens assembly 300 may be provided with a pitch drive shaft capable of rotating the lens assembly 300 such that the objective lens provided at the outermost periphery of the lens assembly 300 is oriented in a desired direction. The lens assembly 300 is satisfactory for transmitting light and condensing the light reflected from the target, and therefore the connection relationship between the sub-component and the sub-component is not particularly limited.

The optical window 400a and the lower optical window 400b are mounted at one open end of the pad 100. The optical window 400a and the lower optical window 400b may be made of a sapphire material having excellent light transmittance so as to transmit light having a desired wavelength and laser light. The optical module 200 and the lens assembly 300 inside the fade 100 irradiate the light to the target through the optical window 400a and the lower optical window 400b and receive the light reflected from the target, For example, the position of the target and the distance from the target. The optical window 400a is mounted at one end in the longitudinal direction of the pad 100 in a direction crossing the longitudinal direction of the pad 100. [ The mounted optical window 400a is spaced apart from the lens assembly 300 by a predetermined distance in the longitudinal direction of the pad 100 on the opposite side of the optical module 200 with respect to the lens assembly 300. The lower optical window 400b is spaced downward from the lens assembly 300 and is mounted on one end of the fad 100 that is opened in the longitudinal direction of the fad 100. The lower optical window 400b is connected to the lower end of the optical window 400a, Form a space. The optical window 400a may be disposed at an oblique angle with respect to the lower optical window 400b.

An optical apparatus 1000 for a sunlight blocking target is disposed at least partially between the optical window 400a and the lens assembly 300 so as to block a solar light incident path formed in a direction crossing the optical window 400a Blind module 500. The target optical device 1000 for blocking sunlight uses the blind module 500 to determine whether to block and pass sunlight incident into the optical device 1000 during operation of the target optical device 1000 for blocking sunlight, The amount of sunlight can be effectively controlled. In addition, the blind module 500 can be mounted within the interior of the optical device 1000 for sunlight blocking, i.e., the fad 100, so that it can be protected against drag caused by outside air while being mounted on and operating the aircraft. For this reason, the blind module 500 can be structured such that a component, for example, a blind 520 described later can be raised, lowered, or rotated after installation, and the blind 520 can be raised / lowered It can be structurally stable even if rotated. Therefore, the optical apparatus 1000 for the sunlight blocking the blinds 500 can raise / lower the blinds 520 in response to the incident angle and intensity of the sunlight incident on the optical window 400a due to the blind module 500 It is possible to effectively control the quantity of sunlight incident on the inside and whether or not the sunlight is blocked.

[ The first belt 512a is mounted on the reamer body 511 so as to be slidable along the reamer body 511 and the blind 520 described later is mounted and supported on the first belt 512a. The second belt 512b is mounted on the reamer body 511 so as to be able to slide along the reamer body 511 from the first belt 512a to the inside of the pad 100. [ That is, the first belt 512a may be located relatively close to the optical window 400a, and the second belt 512b may be positioned further from the optical window 400a than the first belt 512a. The ends of the first belt 512a and the second belt 512b are inserted into and connected to the driving unit 530.

The connection groove 523 serves to accommodate a change in the distance between the first connection rod 522a and the second connection rod 522b that support the blind body 521 when the blind body 521 rotates. That is, when the first connecting rod 522a and the second connecting rod 522b have different rising distances, the first connecting rod 522a rotates without changing the position at a position mounted on the side surface of the blind body 521, And the second connecting rod 522b moves further upward by a difference in the rising distance from the first connecting rod 522a and slides along the connecting groove 523 so that the blind body 521 is connected to the first connecting rod 522a as rotation centers.

The driving unit 530 may include a motor for generating a rotational force and a cylindrical member connected to a driving shaft of the motor, and a winch for winding or pulling a heavy material around the belt may be applied to the cylindrical member. Of course, the driving unit 530 is not limited thereto, and various means for pulling or pushing the belt 512 may be used. The driving unit 530 pulls or pushes the first belt 512a and the second belt 512b by the same length to move up and down the blind 520 and rotate the first belt 512a and the second belt 512b The blind 520 can be rotated by pulling or pushing it by a different length.

The sensor unit 540 may be mounted on the pad 100 at a predetermined distance from the upper side of the optical window 400a. A general optical sensor capable of measuring the intensity and incidence angle of sunlight can be applied to the sensor unit 540. The sensor unit 540 measures the intensity and incidence angle of sunlight and transmits the measured intensity to the control unit 55.

The control unit 550 receives the measurement value from the sensor unit 540 and controls the driving unit 530 as follows. The control unit 550 may sense the incidence angle of sunlight and may control the driving unit 530 such that the detected incidence angle and the upper or lower surface of the blind 520 form a desired angle, for example, a right angle. The control unit 550 receives the intensity of the sunlight from the sensor unit 540 and descends the blind 520 when the intensity of the sunlight is greater than a preset value and controls the driving unit to raise or lower the blind 520 Can be controlled. Accordingly, the blind assembly 500 can control whether or not the sunlight incident on the blind assembly 500 is blocked corresponding to the incidence angle or intensity of incident sunlight. Specifically, the blinds 520 are lowered in an operating environment where the nighttime environment or the intensity of the sunlight is less than the desired intensity (see FIG. 4) and the sunlight intensity is higher than the desired intensity. At this time, the incidence angle of the incident sunlight 530 is sensed, and the angle of the blind 520 is adjusted accordingly, whereby the incidence of sunlight can be more effectively blocked or the amount of light can be controlled (refer to FIG. 5). The intensity of the predetermined solar light, that is, the intensity of the desired solar light, is determined by the intensity of sunlight that can act as noise in the process of demodulating the reflected light of the laser light collected by the lens assembly 300, .

It should be noted, however, that the above-described embodiments of the present invention are for the purpose of explanation and not for the purpose of limitation. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
