Model of a TDI line scan camera and its electronics
This paper proposes a model of a TDI line scan camera and its electronics. The model consists of three parts, the camera geometric model, the TDI CCD line scan sensor model and the electronics model. The camera geometric model gives a perspective transformation from continuous known objects to a discrete image on the TDI CCD sensor. The mathematical relationship between the amount of incident light and the analog output signal of a TDI CCD sensor is established. Finally, the camera electronics including pre amplifier, DC restore, correlated double sampling (CDS), gain amplifier, and A/D converter are modeled. The model of a TDI line scan camera and its electronics is useful to design and evaluate the electronics of the camera, to develop the virtual CCD camera and to research the methods of enhancing the image quality.
