Dual line-scan in colour – Dalsa Spyder3 camera

The Spyder3 Colour camera is well-suited to applications where the objects to be inspected are being conveyed, are free-falling or in some way passing by the sensor. The unique design of the Spyder3 allows it to be used cost-effectively for applications where previously more expensive and less sensitive line scan cameras were used. These applications include inspection of food, drug, cotton, textile, wood, tiles, recycle sorting, and other general machine vision applications. Combining DALSA’s patented dual line scan architecture and high quality pigment colour filters, the Spyder3 Colour provides excellent colour quality, reliability and affordability.

The sensor has two side by side rows of pixels; the first row contains Red (R) and Blue (B) pixels, while the second row contains Green (G) pixels only. The camera offers various data output options, including RGB, RG/BG, or G only, to meet different requirements in a wide range of imaging applications. The two adjacent linear arrays have no spacing in between. This eliminates spatial artifacts and results in high colour quality, especially when capturing images of rotating or freefalling objects. Useful camera features include: flat field correction, automatic white balance and pre-calibration with common light sources (such as white LEDs).

“With the introduction of the Spyder3 Colour, DALSA now offers colour line scan cameras that address the full price/performance spectrum. Cost-sensitive applications can rely on the Spyder3 Colour, while the Trilinear Piranha Colour is available for applications requiring higher speeds. With the Spyder3 Colour’s innovative dual line design, our customers are able to capture excellent colour images with outstanding noise performance and flexibility while meeting their targets on system costs.” said Xing-Fei He, Senior Product Manager at DALSA.
