[0024] The dual-mode optical signal generator described in this embodiment can generate optical signals in two modes, namely, infrared optical signals and laser optical signals, by integrating an infrared light source device 5, a laser light source device 4 and an aiming laser 3 internally, thereby improving the convenience and test efficiency of infrared target recognition capability testing and laser target recognition capability testing of equipment or systems.

[0026] Specifically, in this embodiment, the dual-mode optical signal generator is divided into two parts: a device body 1 and a handle 2; wherein the front panel 12 and the lower panel of the main body are an integrated structure with the main frame, constituting the casing of the main body, and a cover plate, a left side panel, a right side panel and a rear panel are respectively installed at the top, side and rear end of the casing.

[0027] There are infrared light emitting hole 13, 1064nm laser light emitting hole 14, 1550nm laser light emitting hole 15 and aiming laser light emitting hole 16 on the front panel 12; wherein, the aiming laser light emitting hole 16 is arranged in the middle position between the 1064nm laser light emitting hole 14 and the 1550nm laser light emitting hole 15, and the infrared light emitting hole 13 and the laser light emitting hole should be as close to the aiming laser light emitting hole 16 as possible.

[0028] The light emitting direction of the aiming laser 3, the light emitting direction of the infrared light source, the light emitting direction of the 1064nm laser light source and the light emitting direction of the 1550nm laser light source are consistent and parallel to each other.

[0029] In addition, in this embodiment, the reflective countersunk screws and the logo text design are removed from the front panel 12 and all are moved elsewhere. The front panel 12 is painted with non-reflective black paint and all designs that may cause reflections, such as the anti-lost chain, are removed to ensure the accuracy of the test.

[0030] In some embodiments, Figure 5 As shown, a plurality of fixing protrusions 17 are respectively provided on the inner wall of the front panel 12 near each light exit hole. like Figure 8 As shown, the laser light source device 4 includes a 1064nm pulse laser diode 41, which is mounted on one end of a first lens barrel 42 through a pad column, and a first plano-convex lens 43 is mounted on the other end of the first lens barrel 42, and the first lens barrel 42 is set on the fixing protrusion 17 through a fastening screw; like Fig. 9 As shown, the laser light source device 4 also includes a 1550nm pulse laser diode 44, which is mounted on one end of a second lens barrel 45 through a pad column, and a second plano-convex lens 46 is mounted on the other end of the second lens barrel 45, and the second lens barrel 45 is set on the fixing protrusion 17 through a fastening screw; The aiming laser 3 is arranged on the fixing protrusion 17 by means of a fastening screw.

[0031] Specifically, in this embodiment, the light source device of the 1064nm laser light source is a 1064nm pulse laser diode 41, the 1064nm pulse laser diode 41 is installed on one end of the first lens barrel 42 through a pad, and the first plano-convex lens 43 is installed on the other end of the first lens barrel 42; then, the first lens barrel 42 is installed on the front panel 12, and the first plano-convex lens 43 is perpendicular to the light emitting direction of the 1064nm laser light source.

[0033] The lens barrel in this embodiment can provide mounting positions for installing a 1064nm pulse laser diode 41, a 1550nm pulse laser diode 44 and a plano-convex lens. The 1064nm pulse laser diode 41 and the 1550nm pulse laser diode 44 emit light, and the emitted light source passes through the plano-convex lens to generate a 1064nm laser light signal and a 1550nm laser light signal.

[0034] It should be noted that the generator described in this embodiment can generate three different laser target signals in two bands, namely a 1550nm ranging optical signal, a 1064nm indicating optical signal and a 1064nm specific optical signal.

[0035] For the generated 1550nm ranging optical signal, the time width of a single laser pulse signal is in the hundreds of nanoseconds. For generating the 1064nm indicator light signal, the frequency of the generated laser pulse signal is adjustable within the range of 1-100Hz; For generating a 1064nm specific optical signal, the generated laser pulse signal has a specific waveform, and the specific waveform is flexibly adjusted according to the test requirements. Figure 5 , Fig.10 and Fig.11 As shown, a mounting protrusion 18 is provided on the bottom plate, and the mounting bracket 6 is arranged on the mounting protrusion 18 by fastening screws. The driving mechanism is a driving motor 7, and the driving motor 7 is arranged on a side plate of the mounting bracket 6. The output shaft of the driving motor 7 passes through the outside of the mounting bracket 6 and is fixedly connected to the baffle 8.

[0036] The mounting bracket 6 is provided with a light opening corresponding to the infrared light exit hole 13 (the light opening is not shown in the drawings), the infrared light source device 5 is mounted on the mounting bracket 6, and the infrared light signal generated by the infrared light source device 5 is emitted through the light opening and the infrared light exit hole 13; The infrared light source device 5 includes a halogen tungsten lamp 51 and a filter. The halogen tungsten lamp 51 is mounted on the back plate of the mounting bracket 6 through a lamp holder 52. The filter is mounted in the third lens barrel through a pressing ring. The third lens barrel is set on the fixing protrusion 17 through a fastening screw (wherein the filter, the pressing ring and the third lens barrel are not shown in the drawings); A limiting block 9 for limiting the rotation direction of the baffle plate 8 is also provided on the outer side wall of the mounting bracket 6 .

[0037] Specifically, in the present embodiment, the light source device of the infrared light source is a halogen tungsten lamp 51, which is mounted on its mounting bracket 6 through a lamp holder 52, and the mounting bracket 6 is mounted on the bottom plate, and the light opening of the mounting bracket 6 is aligned with the infrared light emitting hole 13 of the front panel 12, and a motor is mounted on the mounting bracket 6, and a baffle 8 is mounted on the motor shaft, and the baffle 8 includes a connecting portion, a shielding portion and a limiting portion arranged on the connecting portion, and the connecting portion, the shielding portion and the limiting portion are an integrated structure, and the connecting portion is mounted on the motor shaft, the shielding portion has a fan-shaped structure, and the limiting portion is a rod-shaped structure, and under the drive of the motor, the baffle can rotate between the light opening of the bracket and the infrared light emitting hole 13 of the front panel 12, and can control whether the light passes through the infrared light emitting hole 13 of the front panel 12, and the limiting portion cooperates with the limiting block to limit the rotation direction of the entire baffle.

[0038] In addition, it should be noted that the infrared light source device 5 in this embodiment can generate three infrared light signals. The radiation intensities of the three infrared light signals change with time differently. They are enhanced light signals, weakened light signals and constant light signals. When the three infrared light signals are generated respectively, the radiation intensities of the generated light signals are divided into high and low levels for use at different distances.

[0040] Specifically, in this embodiment, since the infrared light source irradiates for a long time and generates relatively high heat, the present application arranges multiple fans near the infrared light source and cooperates with the temperature sensor 10 installed in the generator to ensure that the temperature of the infrared light source does not exceed the limit value.

[0041] In some embodiments, Figure 3 As shown, the rear panel is provided with an adjustment switch 110 for switching the light emission mode. The adjustment switch 110 is a five-way switch for switching different light emission modes.
