Different from galvanometer control technology, polygon laser scanner has rotary mirror which adopts advanced bearing and spindle design, rotating speed up to 50,000 RPM, scanning rate over 100 KHz, scanning speed up to 512 m/s (1600 lines/s) and makes ultra-fast and ultra-cutting-edge scanning applications possible. Brushless DC motor and servo system combined to provide excellent performance and reliability, speed stability < 0.05%. Based on FPGA and DSP high-speed digital processing technology and scanning galvanometer core control algorithm. The application of high-resolution micro grating encoder is mostly used in high energy and high pulse frequency laser application scenarios.
Key Features Of Polygon Scanner
Rotary mirror has high linear speed, in the high-speed and high-precision galvanometer application to break the foreign monopoly, to achieve the breakthrough of zero localization, in the leading level at home and abroad.
It can also be used in solar cutting, food and beverage packaging, high speed marking, scanning inspection, medical scanning inspection, optical scanning, laser cleaning, high speed marking, cutting and other fields.

So after taking pictures of my friend's bead spider I put it on top of my scanner while I cropped / resized the pictures for her. It looked so perfect there I almost couldn't put it away.
I live in an old farm house that has lots of real spiders.. yet I still have thousands of ladybugs. Maybe it's time to invest in a Venus Flytrap....
