A Novel Frequency-characteristic-varying Model And It's Applications

A novel frequency-characteristic-varying model in a time period (FCVMIP) of an optical system is presented in this dissertation. The proposed model is used to interpret some phenomena, such as Benham's color and the concoct-disk's color.Benham's color which is our emphasis arises in a revolving top with a black and white sketch. Benham's color, an open problem over one century, is also termed as subjective color. In this work, it is viewed as an optical phenomenon instead of a physiology one. The result of this research shows that Benham's color can be explained well with FCVMIP. Moreover, it is also found that the appearance of Benham's color is just corresponding to the traditional Chroma theory.With the aid of FCVMIP, another important color phenomenon which arises in a revolving concoct-disk is also considered. Concoct-disks are widely utilized to measure the rotating speed and frequency. Color appears and can be captured by a camera when a concoct-disk is irradiated by an old style fluorescent lamp. This phenomenon can be also interpreted by FCVMIP.The validity of the FCVMIP in time domain is verified by the experiments designed in this work.
