Background Art

[0002] High-precision correction and control technology for the transmission and reception optical axis is one of the core technologies of space optical communication, laser radar, laser energy transmission and other systems. These application fields have the characteristics of long transmission distance, variable transmission channels, and complex equipment working environment. The transmitted laser needs to have high output power, small beam divergence angle and high pointing accuracy. Among them, high-precision pointing is the premise of all work. Only by stably transmitting the transmitted light to the target can the purpose of link communication, target detection and energy transmission be achieved. On the other hand, improving the pointing accuracy of the transmitted laser can further compress the beam divergence angle, thereby improving the efficiency of the transmitted laser. Most of the existing laser transmission optical axis control technologies use multiple detectors to detect the transmitting optical axis and the receiving optical axis respectively. The system is relatively complex, and the pointing accuracy is easily affected by factors such as temperature deformation and gravity deformation. Some use one detector to detect the receiving and reception optical axis, but the transmitting light needs to be turned off when detecting the receiving optical axis, which reduces the system efficiency. There are also those that use one detector to image the receiving and reception optical axis at the same time, and two light spots appear on the detector target surface at the same time. Such systems are easily affected by the intensity of the receiving light spot, and the reliability of engineering applications is poor.

[0003] The technical solution of the present invention adopts a detector to monitor the receiving and transmitting light axes.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] High-precision correction control technology for the light-receiving and light-axis is one of the core technologies of space optical communication, laser radar, laser energy transmission and other systems. Only by transmitting the transmitted light to the target with high precision and stability can the purpose of link communication, target detection and energy transmission be achieved. The laser emission control system with monitorable and correctable light-receiving and light-axis proposed in the present invention can realize coaxial control of the transmitting and receiving light axes with high precision and achieve high-precision target pointing.

[0034] like Figure 1 As shown, it is a schematic diagram of the structure of a laser emission control system with a receiving and light axis monitoring and correction in the field of space optical communication proposed by the present invention, comprising an emission light source 1, a receiving and light axis monitoring component 2, an optical axis correction mirror 3 and a telescope 4. The light beam output by the emission light source 1 passes through the receiving and light axis monitoring component 2, the optical axis correction mirror 3 and the telescope 4 in sequence, and is finally emitted to the target;

[0035] like Figure 2 As shown, the placement order of the receiving and receiving light axis monitoring component 2 and the optical axis correction mirror 3 can be swapped, and the light beam output by the transmitting light source 1 passes through the optical axis correction mirror 3, the receiving and receiving light axis monitoring component 2 and the telescope 4 in sequence, and is finally emitted to the target.

[0036] The receiving and receiving optical axis monitoring component 2 includes a detector 201, a focusing lens 202, a beam splitter 203 and a reflector 204. When detecting the receiving optical axis, the reflector 204 does not work, and the receiving light enters the detector 201 after being reflected by the beam splitter 203 and converged by the focusing lens 202, thereby realizing the detection of the receiving optical axis; when detecting the transmitting optical axis, the reflector 204 works, and the transmitting light enters the detector 201 after being reflected by the beam splitter 203, reflected by the reflector 204, transmitted by the beam splitter 203 and converged by the focusing lens 202. The intensity of the transmitting optical axis detection spot is designed to be much higher than the intensity of the receiving optical axis detection spot, and the detection of the transmitting optical axis is realized by adjusting the gain and exposure of the detector 201. The inclination angle of the optical axis correction mirror 3 is controlled according to the receiving and receiving optical axis deviation detected by the detector 201, and the transmitting optical axis is adjusted so that the transmitting light beam is coaxial with the receiving light beam or is emitted to the target at a certain advance angle.

[0037] like Figure 3As shown, it is a specific embodiment of the present invention, the emitting light source 1 comprises emitting light of two wavelengths, which are 1550nm and 1064nm respectively. The 40dBm laser output by the 1550nm fiber laser is output through the polarization-maintaining single-mode fiber 101 and then collimated by the collimator 102 into a 10mm diameter linearly polarized Gaussian beam, which is modulated into a circularly polarized beam by the 1 / 4 wave plate 103. The transmittances of the collimator 102 and the 1 / 4 wave plate 103 are both T=96%@1550nm; the 37dBm laser output by the 1064nm fiber laser is output through the polarization-maintaining single-mode fiber 104 and then collimated by the collimator 105 into a 10mm diameter linearly polarized Gaussian beam, which is modulated into a sharp beam by the phase plate 106. The transmittances of the collimator 105 and the phase plate 106 are both T=96%@1064nm; the beam combiner 107 is a spectral beam combiner with a transmittance of T=98%@1550nm and a reflectivity of R=98%@1064nm. After the circularly polarized beam and the sharp beam are combined, they enter the optical axis correction mirror 3 at 45°, and then enter the receiving and receiving optical axis monitoring component 2 after reflection. The mirror surface of the optical axis correction mirror 3 is a silver-coated reflector with a reflectivity of R=98%@(1550nm and 1064nm) and an average reflectivity of R=95%@450nm~2um. The optical axis correction mirror 3 is a motor-driven tilt mirror with a minimum adjustment step of 3urad. The receiving and receiving optical axis monitoring component 2 includes a detector 201, a focusing lens 202, a beam splitter 203, and a retroreflector 204. The detector 201 is a component of a short-wave infrared CCD detector 20101 with a circular light shielding tube 20102. The response band of the short-wave infrared CCD detector 20101 is 900nm~1650nm, the single pixel size is 5um×5um, and the target size is 512×512. The focusing lens 202 is a cemented lens that eliminates chromatic aberration in the 900nm~1650nm band, with a focal length of 200mm, a transmittance T=96%@(1550nm and 1064nm), and an average transmittance T=94%@(900nm~1650nm). The beam splitter 203 is a spectral beam splitter with a transmittance T=98%@(1550nm and 1064nm) and an average reflectivity R=90% (900nm~1000nm and 1120nm~1500nm). The retroreflector 204 is composed of an attenuation plate 20401, a corner cube retroreflector 20402, and an electric translation stage 20403. The attenuation plate 20401 and the corner cube retroreflector 20402 are fixed together on the electric translation stage 20403. The corner cube prism retroreflector 20402 is silver-coated, with a reflection spectrum of 450nm~2um, a reflectivity of R=96%@(1550nm and 1064nm), and an average reflectivity of 95%; the attenuation plate 20401 is an absorption-type neutral attenuation plate with an attenuation band of 900nm~1650nm and an attenuation intensity of -20dB.The telescope 4 is an off-axis pair, consisting of a first off-axis reflector 401 and a second off-axis reflector 402, with a beam expansion ratio of 10 times, which expands the 10mm diameter transmission beam to a 100mm diameter transmission beam. The wavelength of the received light is 1550nm, and the optical power after entering the telescope 4 is -30dBm.

[0038] When detecting the receiving optical axis, the electric translation stage 20403 is controlled to move the corner cube prism retroreflector 20402 to the left out of the optical path so that it does not work. The received light enters the detector 201 after being reflected by the beam splitter 203 and converged by the focusing lens 202, thereby realizing the detection of the receiving optical axis. For the 1550nm received light, the reflectivity R of the beam splitter 203 is 2%, and the transmittance T of the focusing lens 202 is 96%. Then, the energy of the received light detected by the detector 201 is -47.17dBm, which is higher than the detection sensitivity of the detector 201, and high-precision detection of the receiving optical axis can be realized.

[0039] When detecting the emission optical axis, the electric translation stage 20403 is controlled to move the attenuation plate 20401 and the corner cube prism reflector 20402 to the right into the optical path to make it work. The emission light is reflected by the beam splitter 203, transmitted by the attenuation plate 20401, reflected by the original optical axis of the reflector 204, transmitted by the attenuation plate 20401, transmitted by the beam splitter 203 and converged by the focusing lens 202, and then enters the detector 201, thereby realizing the detection of the emission optical axis. For 1550nm emission light, the fiber laser output is 40dBm, the transmittance of the collimator 102 and the 1 / 4 wave plate 103 are both T=96%, the transmittance of the beam combiner 107 is T=98%, the reflectivity of the optical axis correction mirror 3 is R=98%, the reflectivity of the beam splitter 203 is R=2%, the attenuation intensity of the attenuation plate 20401 is -20dB, the reflectivity of the corner cube prism retroreflector 20402 is R=96%, the attenuation intensity of the attenuation plate 20401 is -20dB, the transmittance of the beam splitter 203 is T=98%, the transmittance of the focusing lens 202 is T=96%, and the received light energy detected by the detector 201 is -17.96dBm. For 1064nm emission light, the fiber laser output is 37dBm, the transmittance of collimator 105 and phase plate 106 are both T=96%, the reflectance of beam combiner 107 is R=98%, the reflectance of optical axis correction mirror 3 is R=98%, the reflectance of beam splitter 203 is R=2%, the attenuation intensity of attenuation plate 20401 is -20dB, the reflectance of corner cube prism retroreflector 20402 is R=96%, the attenuation intensity of attenuation plate 20401 is -20dB, the transmittance of beam splitter 203 is T=98%, the transmittance of focusing lens 202 is T=96%, and the energy of light received by detector 201 is -20.96dBm. The energy of light received by detector 201 detected by 1550nm and 1064nm emission light is much higher than the energy of light received by detector 201 detected by -47.17dBm. High-precision emission optical axis detection is achieved by adjusting the gain and exposure of detector 201.

[0040] The tilt angle of the optical axis correction mirror 3 is controlled according to the deviation of the receiving and transmitting optical axis detected by the detector 201, and the transmitting optical axis is adjusted so that the transmitting light beam and the receiving light beam are emitted coaxially to the target.

[0041] The coaxial adjustment accuracy of the transmitter and receiver is analyzed. The single pixel angle of the short-wave infrared CCD detector 20101 is 2.5urad (converted to the object space). When the signal-to-noise ratio is sufficient, the optical axis detection accuracy is better than 0.1 times the single pixel angle, that is, 0.25urad. The minimum adjustment step of the optical axis correction mirror 3 is 3urad, so the minimum optical axis adjustment step of the system is 0.6urad. Without considering other engineering errors such as control residuals, the coaxial adjustment accuracy of the transmitter and receiver will be better than 0.6urad.

[0042] It can be seen from the above embodiments that the laser emission control technology with monitorable and correctable transmitting and receiving optical axes proposed in the present invention can achieve sub-microradian level transmitting and receiving coaxial correction accuracy, which is sufficient to achieve high-precision target pointing.

[0043] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
