Pixelated Polarizers Optics Datasheet Pixelated polarizers are designed using Moxtek® Nanowire® Technology. Pixelated polarizers are available as two, three and four-state devices for polarimetric imaging. Polarization helps to pull more information from an obscured image to enable clearer imaging. With Pixelated Polarizers, multiple polarizations across the visible and into IR wavelengths can be gathered realtime. This enables 3D imaging technology and extreme low light imaging. Using 8 inch wafer technology Moxtek is able to manufacture these devices in high-volume. Pixel pitch can be customized for different CCD/CMOS sensor arrays.

Then the imaging information must be very carefully overlaid and aligned. The advantage with pixelated polarization on a CCD CMOS array is that you achieve the equivalent information in a single shot that otherwise would require at least two polarizations with two cameras. Pixelated polarization enables real-time 3D imaging without the camera image overlay difficulty. Nanowire ® MOXTEK ® OPT-DATA-1005, Rev B Subject to technical change without notice

Example of Target Discrimination Low Light Imaging- Pixelated polarizers are ideal for low light conditions. Light is used to create contrast. In low light, the image or object cannot be distinguished from background ‘noise’. Color cannot be seen, and the image or object cannot be seen unless something moves causing a change which can be seen. Multiple polarizations at a single moment overcome the lack of color, contrast, and the lack of reference movement enabling the object to be imaged with remarkable clarity and contrast.
