Hybrid TDI (Time Delayed Integration) Line Scan Cameras
TDI, Time Delayed Integration, line scan cameras are used for application which require higher sensitivity. They use multiple line scan stages to provide up to 256 times higher sensitivity while a standard type scans only one time. However, they also have some disadvantages because of the conventional sensor structure's limit. To improve TDI line scanning performance, Vieworks has developed hybrid TDI line scan sensor for line scan cameras. The Hybrid TDI sensor with CCD pixel structure implemented by using CMOS technology allows ultra-high-speed image captures with up to 256 times greater sensitivity. It is the first concept of TDI line scan sensor and Vieworks named it VTDI (Vieworks TDI).
For the VT Series, its cameras offer a wide variety of resolutions. Vieworks' advanced TDI line scan technology, which uses outstanding hybrid image sensors, captures images with up to 256 times higher sensitivity and up to 300 kHz. The series provides three different models based on the mount sizes M42, M72, and M95, all of which are ideal for various applications. In addition, the series adopts various interfaces such as GigE, Camera Link, and CoaXPress for simple system integration. All cameras from the series have exposure control with anti- blooming. Featuring high speed and high sensitivity, this range is ideal for demanding applications such as flat panel display inspections, wafer inspections, printed circuit board inspections, and high-performance document scanning.

Frequently Asked Questions
How does a TDI line scan camera work?
A TDI (Time Delay Integration) line scan camera uses multiple sensor lines to collect light over time, enhancing sensitivity and reducing noise. This makes it ideal for applications requiring high resolution in low-light conditions, such as material inspection.
What are the benefits of using a TDI line scan camera?
TDI line scan cameras offer high-speed imaging with superior sensitivity, reduced noise, and enhanced image quality, making them perfect for high-precision industrial applications, such as packaging, printing, and material handling.
When should TDI imaging be used instead of conventional sensors?
TDI imaging is preferred when inspecting fast-moving objects where maintaining image clarity is critical. Unlike a standard line scan camera, which captures a single line at a time, TDI accumulates multiple exposures as the object moves across the sensor. This improves signal strength and reduces motion blur, making it especially useful in low-light conditions or high-speed production environments such as semiconductor inspection or print quality control.
How does hybrid TDI improve imaging performance?
Hybrid TDI enhances a line scan camera by combining traditional TDI benefits with additional sensor capabilities, such as improved sensitivity and dynamic range. It allows the system to capture clearer images at higher speeds without requiring excessive lighting. This ensures better defect detection, more consistent image quality, and improved performance in demanding industrial applications.
