The polarized sensor IMX253MZR from Sony streamlines numerous tasks in image processing. SVS-Vistek has already showcased several applications that would traditionally require exponentially more effort to achieve. The company’s latest camera, the exo253ZU3, now features this specialized sensor with a 12-megapixel resolution.

New Technology

Sony integrates a matrix of polarizing filters directly onto the IMX253MZR sensor pixels. Each 2x2 pixel array includes filters oriented at different angles (0°, 90°, 45°, and 135°). This design allows for simultaneous measurement of polarization intensity, polarization angle, and light intensity in a single capture.

Areas of Application

Automated image processing leveraging polarization measurements is particularly effective for non-metallic objects. It significantly reduces the complexity of subsequent image processing tasks in many scenarios. This technology will be crucial for integrators working with surface inspection, reflections, transparent materials (such as water, plastic, or glass), and challenging imaging problems (e.g., reading text on dark surfaces).

Models and Interfaces

Cameras equipped with polarized sensors and C-mounts are available in 5 MP and 12 MP resolutions. The new exo253ZU3 from SVS-Vistek, featuring the IMX253MZR sensor, supports a USB3 interface and achieves a frame rate of 30 fps.

Its counterpart, the exo250ZU3 (5 MP resolution), delivers a higher frame rate of 75 fps. Both models are also available with a Gigabit Ethernet interface.
