How does prism technology help to achieve superior colour image quality? A JAI White Paper

In machine vision, achieving top-quality colour images is essential, but it’s often complicated. Many colour cameras rely on standard Bayer pattern sensors, which filter light and lose signal intensity. This often leads to image defects that require a lot of slow, complex processing to fix.

This White Paper introduces multi-sensor prism-based camera technology as a powerful, fundamental solution. This technology expertly splits the incoming light before it hits the sensors, ensuring accurate, full-colour capture without the signal loss and complex "repair" work needed for Bayer sensors.

This White Paper explores multi-sensor prism-based camera technology, its key advantages, and how it represents the future of colour imaging in machine vision to help you achieve superior image quality.

Who should read this White Paper?

This resource is specifically designed for:

  • Vision system designers actively seeking the best camera technology for their colour imaging systems.
  • Engineers and technical leaders working on applications where superior colour quality, low noise, and high detail are critical, such as print inspection or microscopy.
  • Anyone responsible for choosing the right components to achieve optimal performance in demanding colour machine vision applications.

What you will gain from this White Paper

The key takeaway is that superior image quality is mainly determined by how the light is initially captured onto the sensors, not how much you process the image afterwards.

By downloading and reading this White Paper, you will receive valuable, technical insights that enable better system performance, including:

  • The basics of prism technology for multi-sensor area scan cameras, offering a clear and accessible explanation of how they work.
  • The significant technological advantages of prism-based cameras over single sensor RGB Bayer cameras for demanding machine vision applications.
  • An understanding of the key parameters responsible for superior image quality, such as true colour (capturing full colour depth for every pixel), low colour crosstalk , and a better Signal-to-Noise Ratio (SNR).
  • A clearer picture of why multi-sensor prism cameras offer higher spatial resolution compared to Bayer pattern cameras with the same pixel size.
