Generalized Transport-Of-Intensity Equation Based Space-Frequency Image Signal Analysis |
Abstract | ||
|---|---|---|
Light field has two characteristic parameters amplitude and phase, which is a four-dimensional signal. The amplitude can be directly obtained from CCD/CMOS, but the phase cannot. This paper proposed a method to obtain the phase and analysis the whole four-dimensional signal in space domain and frequency domain. We generalized the Transport-of-Intensity Equation into spatially partially coherent system, based on which the phase can be calculated from through focus image signal. Simulation results show that the proposed analysis method yields good performance in image signal analysis. |
