TDI Camera
C10000-401
Time Delay Integration Camera
The C10000-401 TDI camera is useful for a wide range of
imaging applications requiring high speed operation with high
sensitivity simultaneously. TDI is a special image acquisition
method that has been used extensively in machine vision
applications for industrial inspection. TDI imaging is
appropriate for applications where it is desired to record a
linear process over time, or where the aspect ratio of the
subject being imaged is significantly asymmetric. TDI is
particularly useful for low light level scanning applications for
which a typical line scan camera can not make a useful image.
Also, frame readout mode is available for easy focusing.

OPERATING PRINCIPLE OF TDI
TDI (Time Delay Integration):
Time Delay Integration is a technology of scanning in which a frame transfer device produces a continuous video image of a mov-
ing object by means of a stack of linear arrays aligned with and synchronized to the motion of the object to be imaged in such a
way that, as the image moves from one line to the next, the integrated charge moves along with it, providing higher resolution at
lower light levels than is possible with a line-scan camera.
