How is hyperspectral imaging advancing agriculture?

Hyperspectral imaging involves dividing light into thousands of small bands to gain detailed information.  This compares with multi-spectral, which deals with far fewer bands. Every pixel has a complete spectrum in it and this can be used for a variety of applications including mineralogy, agriculture, astronomy, and surveillance.  With lightweight hyperspectral imaging systems mounted on…

Bayer Area Scan Color Cameras compared to 3-CCD Color Cameras, part 1

There is a perception that color precision can only be achieved with 3-chip prism-based (3-CCD, multiple-chip prism, etc.) video cameras.  Because of advances in sensor design, knowledgeable camera designers can now get excellent color images from Bayer patterned image sensors.  These images are so good that all consumer digital SLR cameras use a single chip…
