Ningbo scenic spot responded to tourists' shooting laser show, which caused lens damage. How does laser damage the lens of mobile phone?

Ningbo Scenic Area responded to the lens damage caused by tourists shooting a laser show, saying that it was negotiating with tourists. The mobile phone can't shoot directly at the laser source because the cmos image sensor of the mobile phone is very sensitive to light. If the laser power is high, it will cause irreversible damage to the CMOS sensor of the mobile phone camera, so when the mobile phone camera is aimed at the laser, it will be burned out. According to the staff of the mobile phone repair shop, when the camera of the mobile phone is damaged by laser, it can't be repaired, that is to say, only a new mobile phone can be replaced.

A woman took her family to an amusement park in Ningbo, Zhejiang. When she found that the light in the light tunnel in the park was quite beautiful, she took out her mobile phone and photographed it. Unexpectedly, less than a short time after filming, the mobile phone began to blink and change color strangely, and the woman felt that the mobile phone was not normal. After a while, the mobile phone even lost its normal shooting function. The woman later learned that the reason why her mobile phone camera was broken was because of the laser show in the scenic spot. When the power of the laser show is relatively high, pointing the camera of the mobile phone at the light will cause the camera equipment of the mobile phone to burn out, and the woman will post her experience online, complaining that the garden has not fulfilled its obligation to inform.

For ordinary tourists, it is understandable that if they don't understand the harm of laser performances to mobile phones, they will take out their mobile phones to shoot lasers when they see beautiful laser performances. As a scenic spot, it is an obligation to inform tourists of the consequences of the laser performance, and tell them never to shoot with their mobile phones at the beginning of the laser performance, otherwise the consequences will be at their own risk. If the requirements are not fulfilled, then the scenic spot must bear the liability for compensation. The reason why laser can damage mobile phone components is that the wavelength and frequency of laser are inversely proportional. The shorter the laser wavelength, the higher the frequency, and the higher the frequency, the greater the impact, which will cause irreversible damage to the sensor of the mobile phone.

Next time we go to other scenic spots to watch the laser show, don't shoot the laser show with our mobile phones. As a scenic spot, holding a laser show must fulfill the obligation of informing, otherwise it will be liable for compensation to tourists.
