How will your application benefit from deploying the Piranha ES TDI?

What is TDI, how does it work and why use it?

Dalsa's high-sensitivity (ES and HS) line scan products use TDI (time delay and integration) technology.

TDI is a method of line scanning which provides dramatically increased responsivity compared to other video scanning methods and is based on the concept of accumulating multiple exposures of the same (moving) object, effectively increasing the integration time available to collect incident light. The TDI linescan sensor is made up of multiple lines of pixels. As an object passes under each line it is imaged and added to the image taken under the previous line.

The object motion must be synchronized with the exposures to ensure a crisp image. It permits much greater scanning speeds in low light, or allows reduced lighting levels (and costs) at conventional speeds.

Features and benefits of the Piranha ES TDI

The Piranha ES provides you with the flexibility to choose how you want to image. The area mode of operation facilitates camera set-up by allowing you to focus on a 2D area. You can also use area mode as your regular mode of operation. Other programmable features include number of taps, bit depth, flat field correction, direction control, stage selectability, and gain and offset control.

Deploying the ES cameras allow you to reduce the number of cameras in your system and so also reduce the number of frame grabbers, lenses, computers and cables.

Providing an alternative to traditional line scan imaging, the new TDI family makes it easy and cost effective to switch from line scan to TDI.
