Description

Technical Field

[0001] This utility model relates to the field of telescopes, specifically to a handheld dual-beam rangefinder telescope. Background Technology

[0002] Currently, to meet the needs of different scenarios, telescopes are becoming increasingly diverse in function and widely used. However, there is currently a lack of a telescope that can satisfy both day / night observation and range finding capabilities. This results in the need to carry multiple telescopes and range finding instruments when dealing with complex observation environments and applications requiring range finding, leading to poor portability. Utility Model Content

[0003] The purpose of this invention is to provide a handheld dual-beam rangefinder telescope that integrates daytime observation, nighttime observation, and rangefinder functions, thereby improving portability.

[0004] To solve the above-mentioned technical problems, this utility model provides a handheld dual-beam rangefinder, comprising a front cover assembly, a middle shell assembly, and a rear cover assembly connected in sequence. The front cover assembly includes a front cover, and an infrared lens assembly, a digital lens assembly, a ranging module, and a power supply assembly fixed to the front cover. The surface of the middle shell assembly is equipped with a control button panel and a transmission interface; The back cover assembly includes the display screen assembly and the eyepiece assembly.

[0005] According to the above scheme, the front cover assembly includes a lens cover, which is detachably connected to the infrared lens assembly and the digital lens assembly.

[0006] According to the above scheme, a wrist strap is provided on the side of the middle shell.

[0007] According to the above scheme, the infrared lens assembly includes an infrared lens, an infrared lens connector, and a camera module assembly. The infrared lens and the camera module assembly are respectively fixed on both sides of the infrared lens connector.

[0008] According to the above scheme, the infrared lens assembly includes a compass module, which is fixed to the bottom of the infrared lens connector.

[0009] According to the above scheme, the digital lens assembly includes a white light lens, a white light lens connector, and a white light sensor component; the white light lens and the white light sensor component are respectively fixed on both sides of the white light lens connector.

[0010] According to the above scheme, the power supply component includes a detachably connected battery cover assembly and a battery casing assembly, as well as a battery placed inside the battery casing assembly; the battery cover assembly and the battery casing assembly are electrically connected to the negative and positive terminals of the battery, respectively.

[0011] According to the above scheme, a bracket connection hole is provided at the bottom of the middle shell assembly.

[0012] According to the above scheme, the rear cover assembly includes a MIC board and a proximity switch board.

[0014] Beneficial effects This invention enables a telescope to perform both infrared and white light observations by incorporating an infrared lens group and a digital lens group, and achieves distance measurement through a range-measuring module. When in use, the user inputs operating commands via a control panel. The display screen selectively displays either the infrared image acquired by the infrared lens group or the white light image acquired by the digital lens group based on these commands. The displayed image passes through the eyepiece group and enters the user's eye, thus enabling selective observation of either the white light or infrared image. Compared to traditional telescopes with only a single observation function, this invention's telescope, combining two image observation functions with distance measurement, can be applied to complex observation scenarios and is easily portable.

[0028] Eyepiece system such as Figure 14 As shown, the eyepiece has an exit pupil diameter of 14mm (the exit pupil diameter of ordinary eyepieces is generally around 6mm) and a magnification of 14x, which greatly enhances its applicability under different lighting conditions. It can capture target features more clearly, reduce shadows or vignetting caused by slight eye movements, and improve the comfort and stability of observation.

[0029] Movement block diagram as follows Figure 15As shown, the infrared core module consists of a signal board, an interface board, and an infrared detector. As the core component of the circuit system, the core module enables the acquisition and processing of image signals. The interface board receives and powers both the interface board and the signal board, while the signal board provides power and related drives to the infrared detector. The infrared light signal emitted by the target enters the objective lens of the infrared optical system and is imaged onto the infrared detector at its focal plane. After receiving the infrared radiation, the detector converts it into an electrical signal. In the signal processor, the video signal undergoes A / D conversion, uniformity correction, dead pixel replacement, gain adjustment, and brightness adjustment transformation before being converted into a digital signal output by a dedicated digital video chip. The data is transmitted to the signal board via DVP. The signal board receives the infrared data from the detector, processes it into image and temperature data by the ISP chip, and transmits the infrared image data to the display screen through the interface on the interface board. The image on the display screen is then superimposed on the observed visible light target image by the light fusion system and output, allowing the human eye to observe the fused target image.

[0030] The circuit diagram of the telescope in this embodiment can be found here. Figure 16 The main working principle of this telescope is as follows: the infrared lens collects the infrared light signal emitted by the target, and the core assembly 1027 performs photoelectric conversion and signal processing on the infrared light signal to obtain an infrared image signal; the white light lens collects the white light signal emitted by the target, and the detector in the digital lens group 103 (i.e., the filter module 10313 and the CMOS board 10314) performs photoelectric conversion on the white light signal to obtain a white light image signal; the main control board selectively outputs the infrared image signal or the white light image signal to the OLED 303 (i.e., the display screen) according to the input control signal, so that the human eye can observe the displayed image through the eyepiece group. In addition to displaying infrared images or white light images, the OLED 303 also displays information such as azimuth angle, position distance, and battery level based on the output signals of the compass module 10211, positioning module 205, ranging module 104, and power board 1066.

[0031] It should be noted that the control logic or processing method of each electrical component in this embodiment are conventional technical means in the field and do not belong to the innovation of this invention, and therefore will not be described in detail here.

[0032] This invention achieves a dual-light effect using both digital and infrared images; it can be used as a digital telescope in good daytime conditions with a wide field of view, or as an infrared telescope in complex environments such as jungles at night. Furthermore, it adds a laser rangefinder function to the observation capabilities, allowing for real-time distance measurement of targets. This solves the problem of inconvenient observation in complex conditions and the need to carry a separate rangefinder for long-distance observation. This telescope is a highly integrated product combining optics, mechanics, and electronics, possessing more functions, better environmental adaptability, and easier usability.
