Description

Technical Field

[0001] This invention relates to the field of optical engineering technology, and more specifically to a handheld laser directional energy system. Background Technology

[0002] With the rapid development of drone technology, handheld laser directed energy systems are widely used in the countermeasures against small aircraft. Currently, mainstream laser damage threshold testing systems typically consist of a laser emitting unit, an observation and aiming unit, a control unit, and a power module. They achieve incremental adjustment of the beam divergence angle within a line-of-sight range of 500 to 100 meters by manually adjusting the beam expander, and rely on manual aiming and ranging to lock onto the target. While such systems can achieve basic denial functionality in close-range static scenarios, they suffer from significant technical limitations in complex environments.

[0003] First, atmospheric turbulence interferes with the laser transmission channel, causing wavefront distortion due to fluctuations in atmospheric refractive index. This leads to a decrease in image quality (such as target blurring and edge distortion), while simultaneously increasing the laser spot divergence angle by 30%–50%, reducing energy density below the threshold, and shortening the countermeasure distance by more than 40%. Second, traditional observation and aiming systems lack a real-time phase correction mechanism. When the target is moving at high speed (>10 m / s) or the carrier is vibrating, the aiming error exceeds 0.5 mrad, resulting in a miss rate as high as 65%. Third, aiming requires the operator to compensate for hand tremors, resulting in an aiming-fire response delay of >2 seconds for single-person operation, making it difficult to handle multi-target scenarios. Furthermore, uncorrected aberrations cause laser energy dispersion, requiring an additional 30% or more increase in firing power to maintain effective damage, directly leading to a 50% reduction in battery life and an increase in equipment weight of 2 kg. Summary of the Invention

[0004] The present invention aims to provide a handheld laser directed energy system that solves the problems of poor target image quality, difficulty in aiming at targets and low strike effect of existing laser directed energy systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a handheld laser directional energy system, comprising, The Shaker-Hartmann wavefront detection system includes, from top to bottom, a beam splitter A, a lens C, a beam splitter B, a binary diffractive optical element, a detector, and a lens A and an ultrathin surface deformable mirror, which are positioned on the main optical axis with the beam splitter A. The ultrathin surface deformable mirror is set at a certain angle to the main optical axis, and a MEMS reflector is arranged parallel above the ultrathin surface deformable mirror. The system is used to split the target object imaging light through the beam splitter A to form transmitted light and image light, perform wavefront detection on the image light, and transmit the image of the target object to the visual observation system via the detector. Visual observation system: The visual observation system is coaxial with the optical axis of the Shaker-Hartmann wavefront detection system; it includes a lens B located at the front end of the beam splitter A, the object-side focal point of the lens B coincides with the image-side focal point of the lens A; a transmissive display screen is also provided between the beam splitter A and the lens B, and the transmitted light is transmitted through the transmissive display screen and the lens B in sequence. Atmospheric turbulence correction system: including an ultrathin surface deformable mirror, used to adjust the surface shape to compensate for the phase difference obtained from wavefront detection, so as to eliminate the phase difference; Laser emission system: includes a coaxially arranged laser emitter, lens D, and beam splitter B; used to emit lasers of different wavelengths and to spatially and temporally synchronize the emitted light with the imaging light of the target object; Laser ranging system: includes a laser receiving device, used to receive the laser emitted by the laser emitting system, and calculate the difference between the emission time and the reception time to obtain the distance between the device and the target object; Image stabilization system: including MEMS mirror, which compensates for the real-time jitter of the image obtained by the Shaker-Hartmann wavefront detection system to stabilize the optical path.

[0006] The principles and advantages of this scheme are: 1. This solution employs a Shaker-Hartmann wavefront detection system to detect wavefront phase difference, i.e., to quantify the impact of atmospheric turbulence on the optical channel. Based on the measurement data, an ultrathin surface deformable mirror compensates for the phase difference caused by atmospheric turbulence, thereby acquiring high-resolution images. This addresses the problem of poor target object imaging quality and the inability to acquire high-resolution images in handheld laser anti-drone devices due to the influence of atmospheric turbulence.

[0007] 2. Generally, the imaging system and laser emission system for target observation are spatially separated, located in different atmospheric transmission channels. Even in existing technologies using Shak-Hartmann wavefront detection for laser directed energy emission, the measurement data and the optical transmission channel of the laser emission system are not in the same space-time, leading to spatial discrepancies and inaccuracies in the atmospheric turbulence correction data. Furthermore, the heat generated by the high-power laser during emission significantly affects the atmospheric transmission channel, further complicating the atmospheric turbulence correction data and causing substantial deviations.

[0008] This scheme designs the Shaker-Hartmann wavefront detection system and the laser emission system coaxially. Based on the principle of optical path reversibility, it achieves synchronization of laser and image light in time and space. That is, while the imaging optical channel is being corrected, the laser emission channel in the same space is simultaneously corrected. The spot size is significantly improved, with no diffusion and concentrated energy.

[0009] 3. This solution splits the imaging light. The transmitted light band is used for human eye observation of the target, while the remaining visible light band is provided to the Shaker-Hartmann wavefront detection system to obtain the target image. According to the spatial position of the field of view, it is displayed at a specific position on the transmissive display screen, coinciding with the position of the target's transmitted light. This ensures that, apart from the target object being in normal color (color not distorted), the background is a conspicuous single transmitted light (i.e., color distorted), thus highlighting the target image.

[0010] 4. This solution uses a MEMS reflector to adjust the direction of the laser emission path in real time, automatically locking onto the target. Simultaneously, the MEMS reflector adjusts the field of view in real time, increasing the observation range. This eliminates the need for the user to move their body or arm to adjust the direction, and for distant targets, it solves the aiming difficulties caused by small-angle movement of the equipment.

[0011] 5. The Hartmann wavefront sensor in the Shaker-Hartmann wavefront detection system accurately acquires the small vibration frequency of the image. The MEMS reflector compensates for the acquired frequency, eliminating jitter at the hardware level and ensuring efficient target locking. The eyepiece observation system will not cause the target to miss or become difficult to aim due to the shaking of the holder or the carrier. Attached Figure Description

Detailed Implementation

[0013] The following detailed description illustrates the specific implementation method: This embodiment of a handheld laser directional energy system solves the problems of atmospheric turbulence interference, jitter causing target misses and difficulty in aiming, and low image imaging rate by integrating wavefront detection and adaptive correction technology, thereby improving energy concentration and human-machine collaboration efficiency.

[0014] This invention provides a handheld laser directional energy system that integrates Shake-Hartmann wavefront detection and adaptive correction, coaxial design of the laser emission and detection system, beam splitting to enhance target background difference, dynamic adjustment of MEMS mirrors, and jitter compensation technology. This achieves high-resolution imaging, concentrated energy, easy target detection, automatic locking, and stable aiming. The system is attached. Figure 1 As shown, it mainly consists of a Shaker-Hartmann wavefront detection system, a visual observation system, an atmospheric turbulence correction system, a laser emission system, a laser ranging system, and an image stabilization system.

[0015] The Shaker-Hartmann wavefront detection system includes, from top to bottom, a beam splitter A, a lens C, a beam splitter B, a binary diffractive optical element, a detector, and a lens A and an ultrathin surface deformable mirror, all arranged coaxially. In this embodiment, the ultrathin surface deformable mirror is set at a certain angle to the main optical axis, and a MEMS reflector is arranged parallel above the ultrathin surface deformable mirror.

[0016] Its optical path is as follows Figure 2 As shown, the imaging light of the target object is reflected by the MEMS mirror and the ultrathin surface deformable mirror before reaching lens A. After transmission through lens A, the image light, excluding the transmitted light, is reflected at beam splitter A and reaches lens C. The beam diameter is significantly reduced after passing through lenses A and C, and it is transmitted through beam splitter B. The transmitted light reaches the binary diffractive optical element (equivalent microlens array) and is then imaged by the detector array. The Shaker-Hartmann wavefront detection system calculates the wavefront phase difference based on the array image, which is the quantitative data of the influence factor of atmospheric turbulence on the imaging channel.

[0017] As attached Figure 3 As shown, the target object imaging light is split by beam splitter A using the Shaker-Hartmann wavefront detection system, forming transmitted light and image light. In this embodiment, the transmitted light is a monochromatic background light that highlights the image of the target object. In this embodiment, to better protect the eyes, yellow light is selected for the transmitted light. By separating the original imaging light, it is used as background light to highlight the target object, making distant targets more prominent and clearer, and facilitating observation and aiming.

[0018] Specifically, lens C can move up and down along the optical axis to achieve focusing, so that it can be combined with lens A to achieve the effect of reducing the diameter of the beam.

[0019] Beam splitter A, beam splitter B, and the ultrathin surface deformable mirror all have the same angle with the principal optical axis, ranging from 30° to 45°. In this embodiment, it is set to 45°. The MEMS reflector is parallel to the ultrathin surface deformable mirror, and its tilt angle is also set to 45°. Beam splitter A transmits yellow light and reflects other visible light of different wavelengths, including the laser emitted by the laser transmitter. In this embodiment, the transmitted light can also be selected from visible light of different wavelengths that differ significantly from the target object's color, serving as background light to highlight the target object. In this embodiment, beam splitter A serves to split the visible light into two parts: one for Shack-Hartmann wavefront detection and the other for the visual observation system.

[0020] Beam splitter B is used to transmit visible light and reflect laser light, thus achieving the effect of transmitting visible light.

[0021] Binary diffractive optical elements are ultrathin binary diffractive optical elements, equivalent to microlens arrays. They achieve the effects of reducing size, weight, and cost, and improving array imaging quality.

[0022] In this embodiment, the detector is a photodetector used to form an array image of the received image.

[0023] In this process, wavefront detection is performed on the image light, and the image of the target object is transmitted to the visual observation system via a detector.

[0024] Specifically, wavefront detection involves calculating the impact of atmospheric turbulence on the imaging channel. This includes the image light, after being split by beam splitter A, being transmitted through beam splitter B to the binary diffractive optical element and then imaged in the detector array. The wavefront phase difference is then calculated based on the array imaging.

[0025] In this embodiment, for a circular aperture with an average phase of zero, the wavefront can be represented as a series of Zenike polynomials, expressed as follows: Equation (1), In the formula, The corresponding coefficients of the k-th Zenike polynomial; Let be the k-th Zenike polynomial. By quantizing the centroid shift of each sub-aperture, the average wavefront slope on that sub-aperture can be determined, thereby reconstructing the complete wavefront phase distribution.

[0026] Specifically, as shown in Figures 4(a) and 4(b), the calculation process for the wavefront phase difference includes: Based on the array imaging of the detector, images of the light spot array are acquired. Using the orthogonality of the Zernike polynomial on the unit circle, the centroid coordinates of each light spot are calculated, and the centroid offset is determined. Therefore, the centroid coordinates of the light spots are... Represented as ; Equation (2), In the formula, These are pixel coordinates; Pixel light intensity; The wavelength of the light beam; The focal length of the microlens; The area of ​​the sub-aperture; , denoted as , respectively, the average slope of the sub-aperture wavefront.

[0027] Based on the centroid offset and system optical parameters, the average wavefront slope of each sub-aperture is calculated and expressed as: ; Equation (3), In the formula, The normalized area of ​​the sub-aperture; , , respectively, represent the average slopes of the aberrations represented by the k-th Zenike polynomial in the horizontal and vertical coordinates; The matrix relation equations relating the average slope, the Zenike polynomial, and the Zenike polynomial coefficients can be expressed as follows: Equation (4), In the formula, This represents the total number of effective sub-apertures; Let be the coefficient of the nth term of the Zenike polynomial.

[0028] The Zenike coefficients are obtained by solving the matrix relation equations, and the wavefront phase distribution is synthesized according to the Zenike polynomial series expansion formula. Based on the generalized matrix principle, the coefficients of the Zenike polynomial are calculated to achieve wavefront reconstruction.

[0029] Visual observation system: In this embodiment, the visual observation system is coaxial with the Shak-Hartmann wavefront detection system and mainly includes a lens B located at the front end of the beam splitter A; the object-side focal point of lens B coincides with the image-side focal point of lens A, and the two together form a telescope effect. A transmissive display screen is also provided between the beam splitter A and the lens B, and the transmitted light (i.e., yellow light) formed after beam splitting is transmitted through the transmissive display screen and the lens B successively.

[0030] As attached Figure 3As shown, the imaging light of the target object is reflected by the MEMS and the ultrathin surface deformable mirror to reach lens A. After transmission through lens A, the yellow light is transmitted at beam splitter A, and then transmitted successively to the transmissive display screen and lens B. Simultaneously, the image of the target object acquired by the Shak-Hartmann method is transmitted to the transmissive display screen after being detected. After image conversion, it is displayed at the center position. The image of the corresponding object at the focal point of lens B can be displayed on the central surface of the display screen, thus fusing with the imaging light transmitted from beam splitter A. The fused light is emitted through lens B and reaches the human eye for observation. This achieves sharp image defocusing processing and convolution of some higher-order aberrations.

[0031] In this embodiment, the Shaker-Hartmann wavefront detection system and visual observation system are also used for automated focusing adjustment based on the obtained distance between the device and the target.

[0032] Atmospheric turbulence correction system: includes an ultrathin surface deformable mirror, which is used to adjust the surface shape to compensate for the phase difference obtained from wavefront detection, so as to eliminate the phase difference.

[0033] In this embodiment, as shown in the appendix Figure 5 As shown, the ultrathin surface deformable mirror includes an ultrathin continuous surface embedded in the surface of the mounting base. In this embodiment, as shown in the attached diagram... Figure 6 As shown, the ultrathin continuous surface is an ultrathin mirror. An actuator array is located at the bottom of the ultrathin continuous surface, and a support base is located below the actuator array. In this embodiment, the support base consists of a high-rigidity substrate and auxiliary support mechanical components. Through the mechanical actuator array and the ultrathin continuous reflective surface, the surface shape can be adjusted by the mechanical drive unit, thereby simulating a freeform surface. Its ultrathin design helps reduce the system size and weight, adapting to the lightweight requirements of handheld devices.

[0034] After acquiring the wavefront phase difference, the Shak-Hartmann wavefront detection system transmits the phase difference data to an ultrathin surface deformable mirror. Based on the phase difference data, the mirror adjusts its surface shape, precisely modifying the micro-curvature of the reflecting surface to form a surface shape complementary to the wavefront distortion. This compensates for the phase error caused by atmospheric turbulence, eliminating the phase difference. By compensating for the phase difference in real time, the system ensures wavefront stability of the imaging light and the laser emission light during transmission, improving target imaging resolution and preventing laser spot divergence, thus achieving energy concentration.

[0035] Laser emission system: as attached Figure 1 As shown, it includes a laser emitter, lens D, and beam splitter B arranged coaxially; used to emit lasers of different wavelengths and to synchronize the emitted light with the imaging light of the target object in space and time.

[0036] In this embodiment, the laser emitter emits a laser (such as lasers in the 850nm, 940nm, 1064nm, and 1550nm bands; for the selection of the band, any infrared laser will suffice, the only requirement being that it cannot interfere with the Shaker-Hartmann wavefront detection system and the visual system). The laser beam is collimated by lens D (the red light path in the diagram), reflected at beam splitter B to lens C, transmitted through lens C to beam splitter A, reflected again at beam splitter A, and then transmitted out through lens A. The combination of lens C and lens A achieves a laser beam expansion effect. The emitted light is reflected successively by an ultrathin surface deformable mirror and a MEMS reflector. The direction of the laser emission path is adjusted in real time by the MEMS reflector to change the laser emission direction, automatically lock onto the target, and synchronize spatially and temporally with the target object's imaging light before finally emitting the light, thus improving aiming accuracy.

[0037] A laser ranging system mainly includes a laser receiving device, used to receive the laser emitted by the laser emitting system and calculate the difference between the emission time and the reception time to obtain the distance between the device and the target object. In this embodiment, the laser receiving device is a laser receiver, consisting of a receiving lens and a detector.

[0038] In this embodiment, the laser emitting system emits a low-power laser, and the laser receiving device receives the laser. Based on the difference between the emission time and the reception time, the time-of-flight method is used to calculate the distance between the device and the target object. This distance is then provided to the Shaker-Hartmann wavefront detection system and the visual observation system for automatic focusing.

[0039] Image stabilization system: This includes a MEMS mirror. It compensates for the real-time jitter of the image acquired by the Shake-Hartmann wavefront detection system to stabilize the optical path. In this embodiment, when the user or carrier shakes, the image acquired by the Shake-Hartmann wavefront detection system will jitter synchronously within the field of view. For long-distance magnification and aiming at a target, even slight jitter can lead to momentary target loss. The jitter is then calculated as the frequency of small vibrations in the acquired image. This calculated jitter is converted into its opposite value and sent to the MEMS mirror. The MEMS mirror is adjusted according to the vibration frequency to compensate and stabilize the optical path.

[0040] In this embodiment, a specially designed Shak-Hartmann wavefront detection system is used to detect the wavefront phase difference, i.e., to measure the quantitative data of the influence of atmospheric turbulence on the optical channel. Based on the measurement data, a deformable mirror compensates for the phase difference caused by atmospheric turbulence to acquire a high-resolution image. Simultaneously, the Shak-Hartmann wavefront detection system and the laser emission system are coaxially designed to achieve synchronization in time and space. That is, while the imaging optical channel is being corrected, the laser emission channel in the same space is also corrected simultaneously, resulting in a significantly improved spot size, no diffusion, and more concentrated energy.

[0041] Furthermore, in this embodiment, the imaging light is split by beam splitter A. The yellow light band is used for human eye observation of the target, while the remaining visible light bands are provided to the Shak-Hartmann wavefront detection system. The target image acquired by the Shak-Hartmann wavefront detection system is displayed at a specific position on the transmissive display screen according to the spatial position of the field of view, coinciding with the position of the target's yellow imaging light. Except for the target object, which is in its normal color (no color distortion), the background is a yellow image (color distortion) to enhance the difference between the target and the background, facilitating target detection.

[0042] Simultaneously, the direction of the laser emission path is adjusted in real time using a MEMS reflector, automatically locking onto the target. The MEMS reflector adjusts the field of view in real time, increasing the observation range without requiring the user to move their body or arm to adjust the direction. Furthermore, the Hartmann wavefront sensor can accurately acquire small vibration frequencies in the image, which are compensated for by the MEMS reflector, eliminating jitter at the hardware level and efficiently locking onto the target. This prevents the eyepiece observation system from missing the target due to shakes in the holder or the carrier, thus improving the overall imaging rate and accuracy.

[0043] The imaging results of applying the system in this embodiment to existing application systems are shown in the attached figure. Figure 5 As shown in the figure, the imaging effect of this solution is clearer, which helps to improve the aiming rate and hit rate.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
