I would like an explanation of how a laser can measure a product on a conveyor belt

[sam_sam_sam]

I saw this on

“How do they do it “

The laser was measuring the diameter and the height of the product and the weight of the product and it was a straight line laser light across the the conveyor belt ( this is all that was shown in the video clip of the laser that was used )

What type of product is this that can do this

I want to thank anyone that knows what of laser this is

Unless the dimensions are related to weigh somehow, the weighing would be done by whatever the item was on, be it a table or conveyor.
The smiley box abusers used devices from https://cubiscan.com/ when I worked there.

How does it exactly work that is what I am interested in

It shines a laser out, it captures the differences in the reflection and with software works out the dimensions.

Thanks for the explanation of how this is done

I have one question how accurate it is it

Some cubiscanners use infrared and not laser but the idea is the same.
I've no reason to think they wouldn't be precise.

When I was a technician, I tested and repaired a machine called a sub-micron particle analyzer. That was in 1986. They use a laser to measure particles suspended in triple distilled deionized water. Alignment and frequency of the laser is critical. The laser bounced off of the particles at different angles and were captured with a photo multiplier tubes. It then calculated the atomic weight of the particles. All this technology came about as a result of High Energy Physics experiments and equations that people like Einstein and Stokes wrote called Brownian motion.
