Dalsa launches dual line scan camera

Edited by the Engineeringtalk editorial team Jan 16, 2009

Dalsa Corporation has introduced the Spyder3 Colour dual line scan camera based on Dalsa's Spyder3 monochrome models using dual line sensor technology.

Dual line scan architecture features two rows of pixels and a higher quantum efficiency, tripling image sensor responsiveness without shot noise penalty.

This is beneficial for line scan tasks where integration times are short and struggle for enough light intensity.

The Spyder3 Colour camera is suitable for applications where the objects to be inspected are free falling or in some way as they pass by the sensor.

The design of the Spyder3 allows it to be used in 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.

The Spyder3 Colour combines Dalsa's dual line scan architecture and quality pigment colour filters.

The sensor has two side-by-side rows of pixels; the first row contains red and blue pixels, while the second row contains green pixels only.

The camera offers various data output options, including RGB, RG/BG, or G only, to meet different requirements in a 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 free-falling objects.

Useful camera features include flat field correction, automatic white balance and pre-calibration with common light sources (such as white LEDs).

Dalsa's Spyder3 Colour offers 2k and 4k resolutions with a 14 x 14um or 10 x 10um pixel size.

It provides Camera Link and GigE interfaces.
