32k TDI Camera Delivers High Resolution in Line Scan Imaging

Teledyne DALSA’s Linea HS 32k TDI CMOS TDI camera uses two 16k/5 µm TDI arrays with pixel offset.

Two 16k/5 µm images are captured in real time, then reconstructed to achieve a higher resolution image of 32k/2.5 µm. This upconversion significantly enhances detectability for subpixel defects. One advantage of the technology is that existing lighting and 16k/5 µm lenses can be used without sacrifice in responsivity and MTF with a smaller physical pixel size. OEMs can readily integrate the new camera into existing systems to achieve much higher performance without needing to change any components. The units provide up to 150 kHz line rate in 32k/2.5 µm resolutions, or 5 Gpix/s with very low noise and high sensitivity. They feature active pixel assisted alignment and a Camera Link HS fiber optic interface for high reliability and long cable data transmission. Cameras are compatible with the company’s Xtium2 CLHS series of high-performance frame grabbers.
