The article is about Lidar lasers on cars damaging camera sensors when taking close-up photos, but the same could happen with any laser emitting source - laser pointers, casing-opened CD/DVD players, etc.
Lidar Can Permanently Damage Your Phone's Camera
------------------------------------------------
With the gradual rise of semi-autonomous vehicles, there will
likely be multiple cameras pointing back when you pull out a
phone to take a photo or record video of a car. One reddit
user found out earlier this month that car-mounted lidar
sensors can damage a phone camera under certain circumstances.
It was the technological equivalent of staring directly into
the Sun. Their phone's camera was toast, but only because it
was close-up and pointed directly at the lidar sensor.
Reddit user u/Jeguetelli posted worrying footage of a brand
new Volvo EX90 from his iPhone 16 Pro Max. Nothing was wrong
with the crossover SUV. That was the problem. The lidar sensor
mounted in a pod above the windshield shot out a laser barrage
of near-infrared light into the camera. The damage was
immediate and obvious, leaving behind a red, pink and purple
constellation of fried pixels. You can tell the permanent
damage was to that specific lens because the image returned to
normal after zooming out to a different lens. Jeguetelli didn't
seem too concerned about the incident because he had Apple Care.
Please don't stare directly into the Sun
For its part, Volvo warns vehicle owners not to point cameras at
the lidar sensor. The Swedish manufacturer told the Drive, "It's
generally advised to avoid pointing a camera directly at a lidar
sensor. The laser light emitted by the lidar can potentially
damage the camera's sensor or affect its performance." The
automaker noted that cameras are most vulnerable when close up
and pointed right at the sensor. That said, it's like looking
into the Sun; just don't do it.
As a sign of lidar's increasing reach in the automotive world,
Tesla may finally adopt the technology despite Elon Musk's
long-time skepticism against "expensive and unnecessary" lidar
sensors and his aversion to attaching sensor pods to the
automaker's cars. Luminar Technologies announced in the Q1
financial report earlier this month that Tesla was its largest
customer. The divisive electric automaker purchased $2.1 million
in lidar equipment.
