New line scan cameras for high-speed imagingTwo new additions to the range of Piranha4 line scan cameras from Teledyne DALSA feature improved CMOS image sensor technology to deliver line rates up to 200kHz together with outstanding signal-to-noise. These, combined with versatile imaging modes, can accommodate ever more challenging high-speed machine vision applications.

Offering 2K pixel resolution and available in monochrome and colour versions, the new cameras feature advanced chipsets to deliver high throughput with extended Camera Link cable lengths to 30m. Both cameras can operate at any angle to the web, providing greater flexibility for vision system designs. Advanced features include lens and shading correction, and flat field correction.

A dual line scan camera, the new monochrome Piranha4 can operate in Time Delay Integration (TDI) mode for enhanced sensitivity and signal-to-noise, especially for low light level operation. A maximum line rate of 100kHz is available in TDI mode, whilst line rates of 200kHz are possible in Area mode operation. A high dynamic range mode allows longer exposure time on one line and shorter on the second line to allow even more detail to be captured. Applications include railway inspection, printing, wood, film, and label inspection, and general machine vision applications.

The new trilinear Piranha4 colour model provides independent gain and exposure control for each colour for optimising spectral responsivity. A maximum line rate of 70kHz is possible. Sub-pixel spatial correction enables imaging in aspect ratios other than 1:1 to increase web speed and allow precise colour registration. Applications include 100 per cent print inspection, banknote inspection, package and label inspection, and food inspection.
