▸Polarization is separating the direction of light. In other words, it is supposed to receive specific light components by filtering the desired polarity 
▸‌People can ‌detect only the brightness and color of visible light, whereas insects with compound eyes have the ability to detect ‌anode and polarization information. 

Polarizing Filter

▸Only a specific directional light is transmitted and unwanted reflected light is removed with the polarizing filter.
▸‌It is possible to remove reflected light from the water surface and glass with the polarizing filter.

Polarizing Camera

Quality-improved camera with a polarizing filter in front of the camera lens in order to remove back-light, diffuse reflection(light coming from a specific angle) and reflected light

SAi's Technologies #1
Adjust Polarization  

▸It generates polarized image by controlling the transmitted polarization direction on the camera.
▸You can get the best polarized image by configuring a LCD optical module in the surveillance camera.
▸Sai has applied a LCD polarization filter to the surveillance camera so as to remove the reflected light and improve the image quality and recognition performance for the first time in the world.
▸It is possible to eliminate the risk of mechanical failure by applying voltage to LCD and makes you control automatically through the control circuit .
