Time Delay Integration Cameras
Back to Cameras

TDI 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 object motion must be synchronized with the exposures to ensure a crisp image. The TDI method of line scanning provides dramatically increased responsivity compared to other video scanning methods and permits much greater scanning speeds in low light, or allows reduced lighting levels (and costs) at conventional speeds.

Benefits
More speed: With more effective integration time, you can increase the speed of the target object or inspection web.
Less light, less expense: Instead of high-powered, high-cost, high-temperature halogen lighting with DC power, you can use high-frequency AC or even LED lighting, profoundly lowering your system maintenance costs. TDI operation effectively averages out fluctuations in light intensity to represent a DC light source. This factor alone can justify the increased cost of a TDI sensor versus the cost of using DC regulated light source and a line scan image sensor.

Teledyne DALSA
Eclipse family: Compact. Monochrome. Ultra-fast imaging with low-intensity, low-cost lighting without sacrificing image quality
Single tap, bi-directional, advanced TDI line scan camera combines incredible responsivity (100 times more responsive than standard line scan cameras), a small body, and high speed with advanced features such as programmability, in-camera pixel-to-pixel correction, and finely adjustable gain. LVDS camera interface. Suitable for: space-constrained deployments; applications that demand low-light or cost-effective lighting including bar code readers, web inspection , electronics and semiconductor manufacturing machine vision.
