32k TDI Camera Delivers High Resolution in Line Scan Imaging

April 30, 2020
The Linea HS 32k camera uses two 16k/5 µm TDI arrays with pixel offset to capture two 16k/5 µm images in real time, which are then reconstructed to achieve a higher resolution image of 32k/2.5 µm.

This up-conversion reportedly enhances detectability of subpixel defects. One advantage of this technology is that existing lighting and 16k/5 µm lenses can be used without impacting the camera’s responsiveness and MTF (modulation transfer function) with a smaller physical pixel size. This means that OEMs can integrate this camera into existing systems to achieve much higher performance without needing to change any components. The camera provides up to 150 kHz line rate in 32k/2.5 µm resolutions, or 5 Gpix/s with very low noise and high sensitivity. It also features active pixel assisted alignment and a Camera Link HS fiber optic interface for high reliability and long cable data transmission. The camera is compatible with the Linea Xtium2 CLHS series of high-performance frame grabbers.
