Something Wild Happens When You Try to Take a Video of a Car’s Sensors

Public Service Announcement: Do not direct your phone camera directly in the Lidar sensor.

A recent video clip shows the cause. While enlarging the camera on the sensor posted on the top of the Volvo Ex90, a whole galaxy is burned from the colorful points in the image, and it is formed on the exact place where the flashing light can be seen inside the Lidar device.

What you see is not a lens luminous or a digital defect – it’s real physical damage to the camera. It is permanent.

Reddit user warned: “Lidar laser burns the camera.”

Lidar is short to detect light and range, and it has become a way for auto manufacturers to enable their self -driving cars to “see” its surroundings (unless you are Tesla, that is). The sensors operate mainly by photographing a fixed flow of infrared laser beams to measure the distance to nearby organisms, which the computer uses to form a 3D rebuilding for everything near the car.

We cannot see laser symptoms because they are in a wavelength outside the scope of human vision. But the cameras, on the other hand, are all very sensitive to strong beams. Its small sensors can be damaged if brought near the Lidar source, or if a long lens is used to look at one. like Drive Notes In its coverage, this is why backup cameras are usually not affected, as they use a wide angle lens. In the video, you will also notice that the burning damage disappears when the camera minimizes: this is the camera that travels from a long to one short and not damaged.

Thanks to this, Volvo explicitly warns of the damage of Lidar on its support page and the guide of its owners, But this did not stop some of the surprising owners of Learn about this in the difficult way.

Frankly, we cannot really blame them. This phenomenon has caught a self -driving car engineer, who discovered that the Sony camera sensor is worth $ 2000 He was permanently fried After attending the CES offer, where the cars equipped with a widar were displayed.

This is a risk that is likely to have a Lidar technology for any car and not only Volvo, to be clear. after the Lead The Swedish auto industry continues to warn it.

“It is generally advised to avoid directing the camera directly to the Lidar sensor,” said Volvo actor. Drive. “Lidar’s laser light can destroy the camera sensor or affect its performance.”

“The use of filters or protective covers on the camera lens can help reduce the effect of Lidar’s exposure.” “Some cameras are designed with integrated protection against high -density light sources.”

If you are reading all this, you are worried about the eyeliner, do not worry: According to experts, the lidar symptoms used in cars are not harmful. For example, the Volvo Laser Laser is used 1550 nm, and on this wavelength, light can not even reach the retina.

We still do not recommend staring at them.
