Micro-polarized sensors for impossible measurements

"With micro-polarized sensors, precision doesn't stop when the system moves."

Measuring transparent materials and optical surfaces at sub-nanometer levels—especially in motion—was once considered impossible. 4D Technology changed that with dynamic interferometry powered by micro-polarized sensors. By switching from custom imaging arrays to Sony’s on-chip polarization sensor (IMX250), sourced through FRAMOS, 4D gained both performance and cost efficiency.

The IMX250 enables frame-accurate polarization angle detection at 0°, 45°, 90°, and 135°, eliminating the need for frame-stacking and dramatically reducing vibration sensitivity. Combined with 4D’s patented algorithms, this solution now supports applications in industrial QA, astronomy, lens manufacturing, and scientific research.
