Abstract
The invention relates to a nuclear radiation resisting and reinforcing method of a visual system, which belongs to the field of the protection of physics, nuclear physics, nuclear engineering, X-rays, gamma-rays, corpuscular radiation or particle bombardment according to the division of the international patent classification (IPC) and aims to solve the problem of preventing influences and damages of radiation to the visual system in nuclear utilization. A device for the method comprises at least one visual collection device (4) embedded in a nuclear radiation resistant material (2) and at least two optical functional original components (1and 3) of an optical guide device, wherein the optical functional original components are used as a whole and connected to the visual collection device. The invention is a reinforcing method of a visual system nuclear radiation resistant technology and widely applied to a monitoring and processing system of nuclear radiation environments such as space injection robots, accelerator laboratories, nuclear power stations, nuclear waste processing, and the like.
Description
Technical field
The present invention relates to a kind of anti-Radiation Hardened method of vision system, belong to the anti-nuclear radiation protection of electron device field, being specially adapted to has strong influence or the hurtful intense radiation environment of meeting to the electron device operate as normal.
Background technology
Sighting device is an imperative equipment in many environmental monitoring systems.But in nuclear radiation environments such as robot for space, accelerator laboratory, nuclear power station and nuclear waste disposal, sighting devices such as common video camera or camera are difficult to directly reliable the application.In nuclear radiation environment,, must solve the supervision problem in the intense radiation environment for the running status of on-site supervision work.
When traditional vision system without nuclear hardening is worked under nuclear radiation environment, because a large amount of direct directive images of gamma-rays or video acquisition system, the system that makes very easily damages or image/video quality is had a strong impact on, and can't finish the supervision to the work on the spot situation.Perhaps the life-span of equipment will shorten greatly, bring the intervention cost of great number.
Summary of the invention
The present invention says that the technical matters of solution provides a kind of practicality, reliably, effectively, conveniently has an anti-nuclear radiation ability, suppress infringement and the influence of gamma-rays to vision system, guarantee vision system in intense radiation working environment operate as normal, and realize the supervision of working environment.
The technical solution adopted for the present invention to solve the technical problems:
The present invention includes nuclear radiation shield body, image or video acquisition system, light pipe.Image or vision collecting system be embedded into avoid gamma-rays direct projection image or video acquisition system in the nuclear radiation shield body.Utilize light pipe will need the environmental information guiding image or the video system of images acquired or video.Image or video acquisition system arrive the radiation safety scope by cable with information transmission then, realize the supervision to working environment.
Shield of the present invention is the material that lead, steel, iron, aluminium alloy, aluminium, tungsten, concrete and baryte etc. can play the shielded nucleus radiation.
The present invention is the anti-nuclear radiation ability that is intended to improve image or video acquisition system, avoids harm ray such as gamma-rays that vision system is disturbed and infringement, thereby guarantees stable, the reliable and serviceable life of vision system.
The present invention provides technical guarantee for the enforcement of the vision monitoring under the intense radiation environment and the equipment safety operation under the nuclear environment and disposing task.
Description of drawings
According to reference to the accompanying drawings and make the preferred implementing form that non-limiting example provides, the present invention will be more readily understood, wherein:
Fig. 1 can be used for system schematic that the dead ahead certain limit is monitored;
Fig. 2 is the system schematic that realization monitors short range according to method.
Embodiment
With reference to Fig. 1-2, will be used for according to the present invention now the dead ahead and closely the vision system that monitors of certain limit reinforce and describe.
Synoptic diagram shown in Figure 1 mainly comprises periscopic light pipe 5.This light pipe comprises at least one " light transmission " optical functional element, this light pipe purpose is that the visual information in the monitoring environment is transferred to the opening part of shield by " light transmission " optical functional element 1, is transferred to image or video acquisition system by " light transmission " optical functional element 3 in the shield then.Owing to there is a shield (2), gamma-rays can't direct projection image or video acquisition system, direct projection " light transmission " optical functional element 1 just, and a large amount of gamma-rays generation transmissions has only a small amount of the reflection.Further depleted through " light transmission " optical functional element 3, have only the gamma-rays of minute quantity to be radiated image or video acquisition system (4).
" light transmission " optical functional element of making the so-called periscopic guide piece of as a whole formation is variable on quantity, shape and type, and this depends on that light must be followed so that arrive the length and the type of light path of the opposite end of light pipe from external environment condition." light transmission " optical functional element is physical component and the device with self size and dimension, they are suitable for passing through air transfer light along worth light path, and according to specific requirement work of optics by reflecting (reverberator, mirror and diffusing globe) or transmission (lens, prism and optical fiber)." light transmission " optical functional element suitably the academic title so that light in air, may disseminate less or disseminate in a controlled manner unexpectedly along light path, thereby guarantee to satisfy the efficient that image or video acquisition system are gathered light.
The element (1) of directly accepting light from the system outside is defined as first " light transmission " optical functional element, its design must have the big visual field of trying one's best, can gather superior many information in the environment, finally offer try one's best what visual information of image or video acquisition system by " light transmission " optical functional element 3.
The periscopic optical directory means must have at least two " light transmission " optical functional element so that can work like this: and can increase the quantity of wishing according to light path and the efficient that the requirement of vision system is determined.
Fig. 2 utilizes method of the present invention to realize the vision system that the device short range monitors is reinforced synoptic diagram.Can play equally to gamma-ray shielding with to the collection of ambient image information.
