Abstract
The utility model provides an auto adjusting focus device of a laser snooperscope, which is characterized in that a laser ranging device is added on the laser snoopers cope, a position sensor is added next an eye lens, the laser ranging device and the position sensor are both controlled by a PCB control panel for automatic focusing, and the utility model solves problems that manual and electric focusing are inconvenient. The utility has the advantages that the focus of the laser snooperscope can be adjusted automatically in nights and days, the utility model is convenient and practical, and the distance of observation objects can be detected.
Description
Technical field
The utility model relates to the laser night-vision device that is used for the night observation object image, especially a kind of automatic adjustment focal length device of laser night-vision device.
Background technology
At present, laser night-vision device just is born in China, and its principle is that the laser radiation of sending is being observed on the object, utilizes the collection of lll night vision technology to observe the night vision device of object image.Its method of adjusting focal length has two kinds: a kind of is that manually another kind is electronic.Visual range is long, the visual angle is little, slow-footed characteristics because laser night-vision device has, and therefore, manual, electronic adjustment focal length difficulty is big, efficient is also low.
Summary of the invention
The utility model provides a kind of automatic adjustment focal length device that can replace laser night-vision device manual and electronic automatic adjustment focal length, that efficient is high for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of automatic adjustment focal length device of laser night-vision device, form by the PCB control panel that telescope, the nut that is installed in telescopical eyepiece side and screw rod thereof, drive screw are regulated the stepper motor of telescope ocular focal length and fetched the control step motor by being electrically connected, the ranging laser that has laser ranging system that is electrically connected with the PCB control panel also is installed at the telescope front end; At the other position transducer that the adjusting eyepiece focal length that is electrically connected with the PCB control panel is installed of telescopical eyepiece.
Advantage and the good effect that the utlity model has are: owing to install the ranging laser that has laser ranging system additional and install position transducer additional by eyepiece at the telescope front end, regulate eyepiece by automatically institute being surveyed object distance under the control of PCB control panel with pinpointed focus, not only accurately but also rapid.In addition, laser is invisible light, not influenced by night with laser ranging, and good concealment is simple in structure, also can show night visual range simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, telescope 3 is installed on the front end face of shell 1,, the nut 16 that has screw rod 15 is installed at the side of telescopical eyepiece 5 in order to regulate the focal length of eyepiece 5, the output terminal of one client link stepper motor 13 of screw rod is regulated eyepiece by the step motor drive screw rod.The input end of stepper motor is electrically connected PCB control panel 10, and its action is controlled by the PCB control panel.The light amplifier (IF) 6 that has lens 7 is installed in telescopical rear end, and camera (CCD) 9 is installed behind the light amplifier.Light amplifier and camera are electrically connected PCB control panel 10 respectively, and they are controlled by the PCB control panel.In order to measure the distance of object, a ranging laser 4 that has laser ranging system 8 also is installed on the shell front end face of telescope front end one side, laser ranging system is electrically connected with the PCB control panel by its data line, and the range data of measuring is fed back to the PCB control panel.On telescopical eyepiece one side shell, the position transducer 14 that is electrically connected with the PCB control panel is installed also, determines to regulate the position of eyepiece focal length with this.4 night vision laser instruments 2 are installed, as shown in Figure 2 on the front end face of the housing of telescope symmetria bilateralis position.The display 11 of the observation object image that is electrically connected with the PCB control panel is installed on the shell rear end face, and the power interface 12 that the PCB control panel is installed in the side of shell.
Operating principle:
After laser instrument and PCB control panel energized, laser ranging system utilizes Laser Modulation to measure the distance of observing object, pass to control panel (PCB) through the measured range data of data line output, control panel (PCB) calculates according to these data, calculate and to regulate the angle that stepper motor rotates, export to stepper motor through overdrive circuit, driving the screw drive eyepiece focuses, promptly adjust the focal length of laser night-vision device, thereby reach the purpose of focusing, make the figure of collection clear.
Claims (1)
1. the automatic adjustment focal length device of a laser night-vision device, form by the PCB control panel that telescope, the nut that is installed in telescopical eyepiece side and screw rod thereof, drive screw are regulated the stepper motor of telescope ocular focal length and fetched the control step motor by being electrically connected, it is characterized in that: the ranging laser that has laser ranging system that is electrically connected with the PCB control panel also is installed at the telescope front end; At the other position transducer that the adjusting eyepiece focal length that is electrically connected with the PCB control panel is installed of telescopical eyepiece.
