JAI has released a second version of its Go Series camera lineup with the introduction of the GO-5100MP-PGE model. This new addition to the series is equipped with a standard GigE Vision interface, aligning it with JAI’s original GO-5100MP-USB model which utilized USB3 Vision technology. Both cameras rely on Sony’s IMX250MZR polarized CMOS image sensor at their core.

How Polarization Works in the Sensor

The polarization functionality is enabled by a unique 4-way polarized filter array integrated into the sensor. This configuration consists of four distinct polarizing filters, each oriented at angles of 0°, 45°, 90°, and 135° arranged in a regular pattern across the image sensor surface.

  • Illustration: The Sony IMX250MZR sensor features a specialized design with its polarization capabilities derived from four separate polarizing filters (at angles of 0°, 45°, 90°, and 135°) arranged in a regular pattern.

This arrangement allows each block of four pixels to function effectively as calculation units. These blocks enable the sensor to determine light reflection characteristics including angle and intensity, alongside other analytical functions.

Technical Details

The camera operates at full resolution of 2464 x 2056 pixels. However, due to its polarization design, effective output resolution is approximately 1.25 megapixels.

Advanced Processing Capabilities

Beyond providing raw pixel data with polarization information for each point, the GO-5100MP-PGE incorporates an intelligent processing function that pre-calculates two critical parameters:

  • AoLP (Angle of Linear Polarization): Determines the angle at which polarized light strikes a 4-pixel block.
  • DoLP (Degree of Linear Polarization): Measures the strength of polarized components relative to total incident light on the sensor.

This built-in calculation capability significantly reduces host system processing requirements, freeing up resources for other application tasks.

Other Features

Additional camera capabilities include: * Region of Interest (ROI) functionality * Shading compensation mechanisms * Gamma correction features

Physical dimensions are compact at 29 x 29 x 41.5 mm with a standard C-mount lens interface. Designed for industrial environments, the camera meets stringent shock and vibration specifications (80G/10G respectively) and offers an impressive MTBF rating exceeding 150,000 hours.

Application Examples

The versatility of JAI’s polarization technology extends across various industries:

  • Quality Control: Internal stresses in glass or plastic products can be detected using these cameras.
  • Automotive Safety Systems: Unwanted reflections from vehicle windshields are minimized for clearer cabin monitoring and more accurate facial recognition analysis.
  • Glass Inspection: Scratches, dents, and foreign particles become easier to identify when examining finished glass components such as automotive windows or eyewear lenses.
  • Surface Quality Analysis: Spray-painted surfaces in manufacturing settings benefit from detailed examination capabilities identifying defects like scratches or uneven coatings.
