X-ray TDI camera


X-ray TDI camera is useful for in-line applications requiring high-speed operation, high sensitivity and high resolution with wide area.

C12300-461B supports X-ray inspection at low energy of 10 kV and upwards. It is ideal in capturing images of low-density or thin objects that are difficult to generate contrast on by irradiation of X-rays.

Continuous imaging of moving objects

Operating principle of X-ray line scan camera

X-ray TDI cameras can continuously inspect moving objects inline as they are brought into scanning range and without stopping objects such as metal sheets and separators that are fed in from roll to roll. Continuous inspection in this way means that these cameras can be applied in high-speed lines.

Imaging of object locations without directing X-rays at an angle

Operating principle of X-ray line scan camera

With X-ray inspection using 2D sensors, distortion sometimes occurs in images outside of the irradiation center of the X-ray source as a result of incident X-rays being directed at an angle to objects. This necessitates positional adjustment at each individual image capture point to ensure accurate inspection. Whereas, with X-ray TDI cameras, X-rays are irradiated at right angles to the carrying direction, and imaging is performed by integrating continuously captured images. As a result, distortion-free images can be acquired.

Bidirectional scanning supported

Operating principle of X-ray line scan camera

The C12300-461B is capable of bidirectional scanning (switching of scan direction to match the carrying direction). As a result, this series supports connection to differently oriented lines that use the same inspection systems and systems where scanning is performed in reverse when a defect is judged. It also helps improve cycle time in the inspection of large objects such as PCBs for servers.
