For accurate and instantaneous sub-nanometer interferometric measurements, even in the presence of vibration and motion, 4D Technology developed a micro-polarizer array. But now, the company is excited about the high performance and low cost of Sony's IMX250 micro-polarizer sensor. 4D Technology’s main target applications demonstrate how on-chip polarization can improve and deepen imaging results.
Often, lighting conditions and the type of object under inspection prevent vision systems from producing the best possible image. Excessive light, reflections, haze, or shiny materials can have a negative impact on the image quality; therefore, these conditions affect the results of both the image analysis and the inspection. Polarizing filters or sensors reduce the glare; reduce surface reflections; and, increase the clarity of structures, defects, and shapes.
