Abstract

A laser diode assembly for use in a small arms laser transmitter (ASAT) which may be affixed to the stock of a rifle such as an M16 used by a soldier in training with a multiple integrated laser engagement system (MILES). The laser assembly may include a housing assembly having a forward end with a window through which the beam of the laser diode is emitted. A pair of optical wedges are positioned inside the housing assembly between the laser diode and the window. The optical wedges are supported for independent rotation about a common optical axis for steering the laser beam. An alignment head may be physically mated to the rearward end of the housing assembly for driving a pair of shafts to rotate the optical wedges in the alignment of the transmitter to boresight the ASAT so that a soldier can accurately hit a target once he or she has located the target in the conventional sights of the rifle. The laser diode assembly is made of high-temperature resistant materials and adhesives to minimize variations in focal length that would otherwise result in undersirable laser beam dispersion.

Description of the invention (i) [Background of the invention] Cross-referenced related U.S. patents and patents related to this application are: U.S. Patent No. L4 1 0,815, published on May 2, 1995, and named “'Automatic' Shooter Identification Small Arm Laser Calibration System ", US Patent No. I 4 7 6.385, published on December 19, 1995, named " Laser Small Armor Launcher_ ', and US Patent No. 5, 4 2 6, Published on June 20, 1995. The name is "Multiple Integrated Laser Combat System Using Optical Fiber Detection Signal Transmission". As a reference, the disclosure of the above patent is cited in this application. This application and the aforementioned U.S. patent are issued to Cubic Defense System, Inc. FIELD OF THE INVENTION The present invention relates to a military training device 'and more particularly to an improved laser diode assembly for use in a laser launcher mounted on a rifle for use by soldiers in military training. ‘Using the Skills of the Street’ for many years ’The US Armed Forces has trained soldiers with a multi-integrated laser system (MLS). A feature of the multi-integrated laser combat system (μ I [£ $) involves a small, laser launcher (S ΑΙ) mounted on a step grab (such as M 丨 6) and a grab tube. Each soldier's helmet and strap are equipped with a product = to detect the hit point of the laser " bullet " a soldier pulls his or her ^ trigger to fire an empty ammunition 'simulate a live-fire shot, = A sound sensing device. When the laser launcher is equipped with a small weapon laser launcher (SAT) on the two grab tubes, each launcher must be calibrated so that once the soldier puts the target in the traditional step grab

Page 6 421707 V. Description of the Invention (2) When the cat is in sight, he or she can indeed hit the target. In the past, such small arms laser launchers (SAT) were fixed to the step gun barrel with screws, and the step gun was adjusted with a mechanical or so-called "iron" cat sight to align it with the laser beam. The disadvantage of this method is that when this step grab is used for strike, the mechanical betrothal on the step grab must be readjusted to deafness. To overcome this shortcoming, newer small arms laser launchers (SAT) use mechanical linkages to change the direction of the laser. The calibration of small arms laser launchers (SAT) usually requires a calibration device. The known technique used by the US Army to calibrate multiple integrated laser combat systems (miles) for small and medium-sized weapon laser launchers (SAT) is the small weapon calibration device (SAAF), which includes a Complex array of detectors' These detectors are used in combination with 35 printed circuit boards to determine the position of the laser beam hit point relative to the target crosshair. The difficulty with using this known technology for small arms calibration devices (SAAF) is that the soldiers must blindly locate their weapons at a detector array 25 meters away, but there is no stable platform available. In many cases, the result is that when the soldier shoots his or her weapon, the aiming point is not in the desired position. Because the detector array is located 25 meters away from the soldiers, it also has visibility limitations due to snow, fog, wind, and poor or evening light conditions. In addition, the “Small Arms Calibration Device (SAAF) of the conventional technology” needs to calculate the number of “clicks” in the horizontal and vertical directions. Then, four sets of electronic 'mechanical displays' are used to display the number of clicks on a conventional small arms calibration device (SAAF). The soldier must turn his or her traditional small weapon laser launcher (SAT) adjuster in the correct direction by the corresponding click

Page 7 421707 V. Description of the invention (3) Number :. Then he ’ll have to aim and fire the weapon again and adjust accordingly. This process is repeated until the soldier obtains a zero indication on the known small weapon calibration device (SAAF). This is a time-consuming and tedious process since the soldier must find the target crosshairs every time a normal aiming error occurs. It takes 15 minutes for a soldier to do his best to ^ standardize his or her weapon, but it still ca n’t be accurately calibrated. It ’s not only a small weapon calibration device (SAAF) using conventional technology. High because of the large number of empty ammunition. In a conventional laser transmitter (SAT), a laser cannot be fired without detonating an empty case or using a type of plutonium firing trigger cable. The small calibration device (saaf) of the known technology does not support optical concealment optics, and different types of i2 do not support night vision equipment. Laser calibration of received small arms. In view of this, we have developed some components that no longer need to use large targets and more accurate calibration. And this component worn by ^ J (M1LES) soldiers can identify different shooters in different battles. The killings caused. Known small arms lasers emit laser light ^). \ Grab a laser diode to generate x for small step grab calibration. However, the effective range of current small weapon laser launchers (SAT)

Page 421 707

5. Description of the invention (4) May be limited. This limitation is due to the 42w t change in small arms subject to internal and ambient temperature changes at the site where the weapon is used. For example, the imitation of an empty ruthenium shell can cause the lambda grab tube and the small weapon laser mounted on it to heat up, or the weapon is used in a sub-zero temperature area, in this way. This heating and cooling can be mT ) The efficiency of the laser diode is reduced, resulting in a reduction in the density of the laser beam emitted by the laser beam. 2 The 3 types of shots that should have caused L to be killed may not be detected and therefore not recorded as killed. . It is therefore desirable to provide an f-emitting diode assembly for advanced small weapon launchers that enables small weapon laser launchers (SAT) to be positive, normal, and wide over a wide temperature range. This type of laser diode assembly is also best if the laser beam emitted by the small weapon laser launcher (SAT) is light and light: the parts should be molds, and the structure 1 reduces manufacturing costs and enhances battlefield survival Force * 7 · ^ · [Comprehensive description of the invention] Therefore, the main purpose of the present invention is to provide an improved laser swap body component N for use in a multi-integrated laser combat system. The present invention provides a Larger effective diode diode assembly when subjected to temperature changes. In other words, when such a laser diode is mounted on a small weapon laser launcher (SAT), the effective "hit" range of the small "" laser launcher (SAT) can be increased, ' Over adoption

The range that the small weapon laser launcher (SAT) of invention description (5) can currently reach „This component includes a modular structure, which can reduce manufacturing costs and strengthen control of manufacturing tolerances. ^ The laser diode assembly consists of a nearly cylindrical hollow branch and a laser diode tube. The laser diode sleeve is fixed at one end of the support and coaxial with the support, so, The laser beam emitted by the laser diode mounted in the laser diode sleeve can pass through the inner hole of the support body.

The cylindrical laser diode sleeve 242 is connected to the rear end of the selector 236 through a coupling joint 238. The lens 240 is housed in the coupling joint 238. The mounting plate 234, the lens 240, the coupling joint 238, and the support 236 are bonded with a high-temperature epoxy resin or another suitable adhesive. This special adhesive is used to eliminate thermally induced offsets, otherwise, the laser diode sleeve 2 4 2 may be offset with respect to its longitudinal optical axis. The lens 24 can be laser welded to the laser diode sleeve 242 'instead of bonding the two parts together with an adhesive. In this embodiment, the wavelength of the laser emitted by the 'laser diode sleeve 242 is approximately 12.5 to i 0 micron.

Description of the invention (u) When assembling the laser diode assembly 300 (Fig. 2), the drive shafts 218 and 220 pass through the holes 219 and 221 'and the auxiliary gears 218a and 220a and the retaining ring The spur gears or toothed sections on 228 and 230 mesh. Light splits 224 and 226 are also bonded to the retaining rings 2 2 8 and 2 3 0 with similar high-temperature epoxy resin or other adhesives. Similarly, the retainer 252 and the end plate 232 may be respectively bonded to the joint 238 and the support 236 with the same high-temperature-resistant adhesive. The beams 224 and 226 can independently rotate around the longitudinal axis of the laser diode assembly 300, which is substantially the same as the laser beam being steered (aimed). One suitable high temperature resistant adhesive is a cured epoxy adhesive such as manufactured and sold under the trademark Epotk 35 3 ND. This epoxy resin cures at a high temperature, and its Tg is at least 10% to 15% lower than the expected minimum operating temperature of Advanced Small Arm Laser Launcher (ASAT) 200. This epoxy resin is made of ceramic or glass powder Do stabilizers as well. Another suitable epoxy resin adhesive is a mixture of Ε ρ ο η 8 2 8 and a certain proportion of hardener, whose T g is much higher than that of advanced small weapon laser launcher (ASAT) 2 0 0 The temperature to which the laser diode assembly 300 is subjected.

The same is true for the retaining ring 228, the retaining ring 230, the retaining ring 252, and the beam splitters 224 and 225. As an example, the lens 240 is made of Corning Glass' material C0550, and the light splitting can be made of Geltex's material SF.

Page 19 ^ 21707 V. Description of Invention (15) 12 Manufacturing. The other parts of the laser diode module 300 may be a commercially available Kovar (trademark) material. The advanced light weapon laser launcher (ASAT) 2 0 has a modular design structure, and the problem of divergence of the laser beam has been overcome. In addition, the use of non-UV-cured high-temperature epoxy resin to manufacture modular components also has the benefit of reducing manufacturing costs. The advanced small weapon laser launcher (aSAT) 200 shown in Fig. 2 has mounting splints 2 4 6 and 248, which share four pins at each end and are respectively connected to one side of the base 202 of the housing assembly. Three of these pins 250a, 250b, and 250c can be seen in FIG. These pins pass through ribs extending parallel downward from the bottom face of the base 202. The mounting clamp 246 can be hingedly attached to the base 2 0 2 of the housing assembly with a pin 250a. The second pin 250b is mounted on the base 202 of the housing assembly opposite the pin 250a. The shape of the mounting clamp 246 is designed such that when the second pin 250b is installed, the mounting clamp 246 and the base 2 2 of the housing assembly are still detachably connected. Similarly, the splint 2 4 8 can be connected to the opposite position on the base 2 2 of the housing assembly with the two remaining pins. The mounting splints 24δ and 248 can be held on the grabbing tube 44 of Step 14 regardless of whether they are used alone or at the same time. Pins 250a, 250b, and 250c are used to ensure the advanced small weapon laser launcher (ASAT) 200 and grabbing tube 44 Removable connection. With this connection mechanism, when it is necessary to remove the advanced small weapon laser launcher (ASAT) 200 from the grab tube 44 of the step 14, it can be easily removed. FIG. 3 is a vertical cross-sectional view of the laser diode assembly 300 shown in FIG. 2. The area around the Advanced Small Arms Laser Launcher (ASAT) 200 is shown on the map.

Page 20 421707 V. Description of the invention (16) 〇 It is indicated by dotted line. The mounting plate 2 34 protrudes from the support body 2 36 so that the laser two module 300 can be mounted on the base 200 of the housing module. The longitudinal optical axis 2 41 of the laser diode 242 is coaxial with the beams 224 and 226 (Figure 2). Schematic B of the solid-state laser diode 242a (Figures 4 and 5) is installed in a fixed center position in the rear end of the laser diode sleeve f. The laser diode 242a can be contained in a metal can, and the same kind of high temperature resistant epoxy tree wall mentioned in this article can be used to fix the metal can to the bottom of the laser diode sleeve 242. Or 9, the metal can is laser welded to the laser diode sleeve 242 with glue. The worm plate seals 232 (Figure 3) on the front end of the cylindrical support body 2 36, and the laser diode 242 is sealed on the back end of the support body 236. "For clarity, the drive shafts gig and 220 and the guard ring The spur gears 218 & 218 and 230 on 228 and 230 are shown only partially. The removable top cover 204 is indicated by a dashed line in FIG. 3, and the base 200 of the housing assembly is also indicated by a dashed line. It can be clearly seen from the circle 3 that the laser diode sleeve 242 is a long cylindrical casing 'and most of it is housed in a cylindrical support 236. ^ As can be seen from FIG. 4, the laser diode assembly 300 emits a laser beam 40 2 when excited. In an ideal case, the laser beam 402 does not substantially diverge, that is, the laser beam is far away from the laser diode 242a ^ due to the propagation of the beam, and its ^ = will decrease. In other words, the distance τ (representing the distance from the edge of the laser beam to the center line of the laser beam ^) remains substantially constant. This divergent characteristic is related to the focal length f of the lens used in the polar body assembly 300, which is well known to those skilled in the art and discussed further below. The focal length f is plotted in ′, 白, white ^ 4 and 5, where the multiple of the number in front of f is equal to the laser diode 242a to the laser diode shown in FIG. 2

Page 21 42 1707 V. Description of the invention (17) The distance of the lens group of the module 300. In other words, if the distance between the laser diode 242a and the lens group is increased, the distance between the lens group and the point marked f in FIG. 5 is also increased. In circle 4, the divergence angle of the laser beam 40 is zero (that is, it does not diverge), and the laser beam is substantially constant with respect to the optical axis 241 within a given distance. For the purpose of calibration The radiation beam 402 is kept parallel to the centerline (CL) 404 of the rifle tube 406 of the rifle 14. 〇 FIG. 5 shows the divergence of the laser beam in the preferred embodiment of the present invention. Figure The unadvanced small weapon laser launcher (ASAT) 2000 is mounted on a grab tube 406 with a calibration centerline (CL) 404. When the laser beam 402 is far from the lens (the density of the laser beam is measured at the lens), since r increases, its density decreases. Therefore, in order to control the divergence of the light beam, the focal length in this embodiment is set between 6. 2 to 18 mm. Divergence angle 0; may vary, depending on the extent to which temperature increase or decrease adversely affects laser diode module 300. For example, when repeatedly firing an empty ammunition, step-by-step 14 repeatedly calibrated with an advanced small weapon laser launcher (AS AT) 2000, which causes the laser diode 242a to be repeatedly energized, and the grab tube 44 may expand. Grab the tube 4 4 expansion film due to multiple firings and the heating of the Advanced Small Arms Laser Launcher (ASAT) 2000, which caused it to heat up. As a result, the manufacturing step 14 and the Advanced Small Arms Laser Launcher (ASAT) 200 were manufactured. Material swells. If the support body 2 36 of the laser diode assembly 300 and other parts expand due to heat, the focal length between the laser diode 242a and the lens assembly increases in proportion. A proportional increase in focal length may also increase the divergence angle α and cause a reduction in the density of the laser beam 402. Moreover, an increase in the divergence angle α also results in a large distance τ (the distance from the optical center to the laser beam at a certain range).

Page 22 421707 V. Description of the invention (18) The laser beam pattern is increased. As a result, the density of the laser beam 402 is reduced, and it may not be possible to activate a multi-integrated laser combat system (MILES) indicator worn by soldiers during confrontation exercises. In the shorter range, the divergence of the laser beam may cause erroneous hit records. For example, 'although the live ammunition fired from the gun barrel of Step 14 did not hit the target, "the laser hit" may be recorded. In other words, the laser beam 40 is no longer aligned with the center line of the rifle 14 ( cl) 404 aligned.

The present invention overcomes the aforementioned difficulties caused by a reduction in the density of a laser beam used in a laser combat system. The laser diode assembly 300 used for the advanced small plastic weapon laser transmitter C ^ S20 0 _ adopts a modular structure, and the predicted maximum work for the advanced small weapon laser transmitter (ASAT) 200 is Within the range of ▲ degrees of the physical ^, the laser diode assembly 300 can maintain the buried adaptability. of. ί ί ^ The axis and optical axis are aligned to an error of less than 1 milliradian. It is possible that the relative f number of the relative mirror is about 3 'and the effective waist diameter is selected within the manufacturing tolerance. Moreover, the laser and the fixed laser diode 2 4 2 a 'can do this. It is known that the tube-like packaging and segmented structure of the similar-polar body and 300 pieces also overcomes the limitation of the φ pseudo of the double technique. Use and design of stubborn die, the above-mentioned resistance to high temperature dry adhesive in manufacturing. 'The use of two-temperature-resistant materials has reduced the emission of laser beams.
