CMOS TDI cameras deliver high-speed colour imaging

Article By : Teledyne Dalsa

Data throughput of the 8k and 16k models is beyond 3GB/s on a single CX4 cable to aid inspection reliability.

Optimised to provide high-speed colour imaging, Teledyne Dalsa's latest additions to its Piranha XL cameras feature multi-line colour CMOS TDI (time delay and integration) technology.

The 8k and 16k models, which make use of Teledyne's CMOS sensor architecture, deliver high sensitivity for colour imaging using four rows per RGB channel for a total of 12 rows. Data throughput is beyond 3GB per second on a single CX4 cable. When combined with Teledyne DALSA’s Xtium-CLHS frame grabber, system designers can expect reduced inspection and manufacturing costs and the reliable transfer of information at extreme speeds.

Key features:

  • High sensitivity colour TDI for high-speed colour imaging with 4x the responsivity of a single-line tri-linear camera through TDI summing of 4 rows per colour making it ideal for low-light conditions
  • True RGB colours–outputs native colours without interpolation
  • High speed and high resolution–inspects more in less time with a maximum line rate of 210kHz (70kHz x 3) in full colour mode in either 8k or 16k resolution
  • Exposure control with a common exposure time for better image quality and minimum impact from encoder jitter
  • Parallax and sub-pixel spatial correction for ease of integration in challenging environments

The field-proven, industry-standard CLHS interface and built-in Trigger to Image Reliability (T2IR) framework safeguard every bit in the camera’s full throughput. While CLHS inherently provides data packet resend and immunity from single bit errors, Teledyne DALSA’s T2IR provides monitoring, diagnostics, track and trace, and buffers to prevent data loss.

Several cable vendors now offer CLHS copper or active optical cables for proven long distance, full bandwidth data transfer for Piranha XL cameras and Xtium frame grabbers.
