CMOS color line-scan camera delivers 8k resolution
Test & Measurement World Staff - September 19, 2012
Powered by CMOS dual-line-scan imager, Teledyne Dalsa’s Piranha4 color camera provides a 7×7-µm pixel size and 8192×2-pixel resolution at a maximum line rate of 50 kHz for high-throughput machine-vision inspection applications. The camera’s CMOS bilinear line-scan technology with on-chip CDS (correlated double sampling) and on-chip ADC offers low read noise and high full-well capacity, resulting in better dynamic range for demanding inspection tasks.
Programmability features of the Piranha4 color camera include exposure control, gain setting, flat-field correction, white balance, and color correction. Special algorithms allow defocusing capability in flat-field correction and white balancing without having to adjust the optical lens. In addition, a GenICam-compliant interface makes the camera easier to set up, control, and integrate. The color version of the Piranha4 can be used for automatic optical inspection of flat-panel displays, electronics, printed material, solar cells, film, and large-format web inspection.
