The imaging micro lens can carry out incoherent combination on multiple paths of pulse lasers, only one pulse laser is shown in the embodiment, incoherent combination of any number of paths can be realized, and the number of the combined lasers is the same as that of the micro lens array. The more lasers that are combined the further the distance of illumination.
After the pulse laser is transmitted to the micro-lens, the pulse laser is imaged on the detector, the light spot on the detector represents a focusing light spot of a far field, the center of mass of the light spot can be obtained through image processing, the deviation of the center of mass of the light spot and a calibration quantity of the initial adjustment represents that the optical axis has deviation from the actual optical axis, and therefore the implementation calibration of the optical axis can be achieved through the illuminating laser moving mirror 23.
The working principle of the TIR prism and the DLP chip is as follows: the TIR relay imaging optical system imaging lens 17, the TIR relay imaging optical system imaging lens 18 and the TIR prism lower half part 13 form a relay transmission optical system, and since the DLP chip has a specific size, the laser output from the pulse collimated laser needs to be matched with the DLP chip, a relay transmission optical imaging system is needed, and the optical system of the imaging system is shown in fig. 7.
The TIR prism is composed of two parts, i.e. an upper part 12 of the TIR prism and a lower part 13 of the TIR prism in fig. 1, the two triangular prisms are combined together by dispensing at four corners thereof, the dispensing position is shown in fig. 3, and the principle is that when light passes through the primary mirror 1 of the transmitting telescope in fig. 2, the light reaches a bonding surface and then is totally reflected, because dispensing causes the two triangular prisms to generate a small air gap, the light is transmitted from a dense medium to an optically sparse medium and totally reflected.
After the pulse laser transmitted by the relay passes through the DLP chip, the pulse laser generates reflection on the surface of the chip to control the switch of the DLP chip, so that whether the chip unit of the DLP generates deflection or not can be controlled.
The emitted main laser light is coupled into the coude optical path through the beam splitter 10, the pulse laser light is reflected into the coupling optical path through the beam splitter 10, the chain line in fig. 1 represents the transmission path of the emitted main laser light, and the solid line in fig. 1 represents the transmission path of the pulse laser light.
The transmitting laser and the illuminating laser are transmitted to the target through the common aperture of the off-axis transmitting telescope.
The imaging principle of the precisely tracking optical system is that the imaging path is in the direction of the reverse arrow in fig. 1, and the imaging path is sequentially an inverted transmitting telescope (a primary transmitting telescope mirror 1 and a secondary transmitting telescope mirror 2), a fast reflecting mirror 3, a kude light guide path (comprising a kude mirror 5, a de mirror 6, a kude mirror 7, a kude mirror 8 and a kude mirror 9), a TIR prism and a DLP chip, and images in a short wave optical imaging system 16 after passing through a short wave imaging reflector 14 and a short wave imaging reflector 15.
In operation, after the illumination pulse laser 25 sends out a pulse, after passing through the TIR prism and the DLP chip, the DLP chip is in a cut-off state at the moment, the pulse laser can pass through the Kude optical path and irradiate on a target after the off-axis emission telescope, after the single pulse laser passes through an image returned by the target, the DLP chip is electrified at the moment, the chip can generate deflection of 16 degrees, and in the gating time and in the gating distance, the light returned by the target passes through the inverted emission telescope, the fast reflecting mirror 3, the Kude light guide optical path, the TIR prism and the electrified DLP to be imaged on the infrared optical system, so that the imaging information of the target is obtained. The illumination laser emits the next pulse, at the moment, the DLP chip is turned off, and the next pulse is emitted to the target through the transmitting telescope.
After the target information is obtained, the miss distance of the target imaging can be obtained, and the miss distance is reduced to the minimum through the fast reflecting mirror 3, so that the precise tracking control of the target is realized (the initial tracking of the target is realized through the photoelectric tracking control turntable before the precise tracking).
When the distance of the target is changed, the emitting angles of the pulse lasers at different distances are focused through 22 in fig. 1, and the radiation fluxes of the target at different distances are realized.
