can pass security check.
Camera is an optical device used to form images using the principle of optical imaging and record images using negative films. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment, astronomical observation equipment, etc.
After the light reflected from the photographed scene is focused through the photographic lens (the scene objective lens) and the shutter that controls the exposure, the photographed scene forms a latent image on the photosensitive material in the dark box , and it forms a permanent image after washing (i.e. development and fixing). This technology is called photography , which is divided into general photography and professional photography.
"Can X-ray security check harm the camera?
Of course, this cannot be generalized. After all, the camera is also divided into digital and film. Let's first talk about the digital camera that everyone wants to know.
"Everyone has said that security check is not good for the camera, so what part of the camera is most likely to affect X-ray? ”
Answer: The most likely impact of X-ray is the camera's CCD or CMOS, then are photosensitive elements sensitive to X-rays? X-rays are invisible and will not affect photosensitive elements in theory.
But any radiation will cause pixel failure to become bad points, and X-rays have the same effect, but the probability is small. Even if you install it in a metal box, the X-speed switch will automatically increase the dose until you see what it is inside through. Therefore, robot cameras working in the radiation area in nuclear power plants always have many bad points because they are radiation.
It is best not to let the camera be repeatedly scanned by X-ray for a long time.
"Is it reliable to carry a SLR over the subway and airport security checks? "
I believe senior photographers have experience. When passing subway or train station , you can carry your camera with you for security check. Generally, security inspectors will not force X-ray machine to pass.
even if you pass the security check, subway or train station security check machine X-ray dose is actually relatively small, and the X-ray power of airport hand luggage security check is also relatively low html l1, generally not affected. Especially according to the available information, the X-ray security machine used at the airport is much more advanced than in the early years. In other words, it only requires a very small power to achieve the purpose of looking through objects.
However, remember that the camera should not be checked, do not checked, do not checked, do not checked ! The X-ray dose of checked luggage is much larger than that of hand-held luggage, and checked luggage may be violently dropped, and lithium batteries cannot be checked (do not carry more than two pieces, and cannot exceed 160Wh).
