The camera of mobile phone is illuminated by laser. What should I do if there is light spot when taking pictures?

If you turn on the camera of your mobile phone and find strange spots, cross hairs or even a screen, then your camera of your mobile phone is probably damaged by the laser.

Why can't the camera see the laser? Laser, also called laser, has the characteristics of high energy and accurate focusing, and is called "the brightest light".

Ordinary light diverges, illuminating all directions, and the power is evenly radiated to the whole space. Finally, only a small part of the power enters the human eye and the camera. However, the power of laser is very concentrated, which has quite strong directionality, and the energy emitted from a single point is extremely high, which can quickly heat sensitive surfaces and cause damage.

Everyone played when I was a child, holding a magnifying glass in the sun, focusing on the place where the solar energy lit the paper. Laser is like a focused beam, and the photosensitive element of a camera or mobile phone camera is like paper. If the heat received per unit area is too high, it is easy to be decomposed or even melted.

In addition to the mobile phone camera, the imaging principles of cameras, monitors, human eyes and animal eyes are similar. If the laser is direct, it will also cause irreversible damage. Therefore, in daily life, you must also pay attention when using a laser pointer, and never look at your eyes.

How to protect the camera? When you see a light source similar to a "light beam", be careful not to pat it. Hold your mobile phone and face the light beam directly. Don't let the strong laser shine directly on your eyes. Of course, it is not a problem to shoot a beautiful light show when it is not in the laser strafe area and it is certain that there will be no direct laser coming.
