Description

Technical Field

[0001] The utility model relates to the technical field of infrared detectors, in particular to a device for reducing vibration of infrared detectors and reducing horizontal stripes of output images. Background Art

[0002] During the production process of infrared detectors, due to the limitations of the use environment, impact vibrations will occur in different scenarios. During the vibration process, the infrared detector circuit has weak anti-vibration ability. When the image is output during the impact and vibration process, the image will produce horizontal stripes related to the intensity of the impact and vibration.

[0003] Specifically, current infrared detectors usually adopt rigid fixation during the production process. Direct rigid fixation can meet the strength requirements, but has no shock-absorbing effect. The probability of generating horizontal lines is very high, which depends entirely on the quality of the chip itself, the circuit design and the impact and vibration resistance of the electronic components themselves. Some are good and some are bad in the same batch, and the yield of the detector itself will be reduced.

[0004] In order to solve the problem of horizontal stripes caused by vibration, the existing technology usually optimizes the image part through algorithms. However, the optimization of the backend through algorithms requires very high capabilities. The algorithm firmware optimization is equivalent to patching, which cannot fundamentally solve the problem of horizontal stripes in the output image caused by vibration. In addition, there is a risk of algorithm failure. Utility Model Content

[0005] The main purpose of the utility model is to provide a device for reducing shock of infrared detectors and reducing horizontal stripes in output images, aiming to reduce the impact and vibration to the detector itself and thus reduce the influence on the output image, and solve the problem of horizontal stripes in the image output caused by the impact and vibration of the environment during the use of the infrared detector.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a device for reducing vibration of an infrared detector and reducing horizontal stripes of an output image, comprising: a housing, a cover plate, a buffer, a detector body and an FPC cable.

[0007] The buffer and the detector body are arranged in the shell, the buffer is located between the detector and the shell, and the buffer wraps the detector body. The cover plate is located at the front end of the detector body and covers the shell. The FPC cable is located at the bottom of the detector and is connected to the outside through the through hole of the shell.

[0008] A further technical solution of the utility model is that the buffer is made of silicone material or rubber material.

[0009] A further technical solution of the utility model is that the shell is a cubic structure.

[0010] A further technical solution of the utility model is that the cover plate is snap-connected to the shell.

[0011] A further technical solution of the utility model is that the cover plate is square, a latch tongue is arranged in the middle part of the four sides of the cover plate, and a latch groove corresponding to the latch tongue is arranged on the four sides of the shell.
