| Abstract: | Spectral-domain Optical Coherence Tomography is used to detect the thickness of cell model dynamically.The method of Spectral Interferometry is introduced to process the signal by Discrete Fourier Transform.SD-OCT measurement system is set up and a platform is designed specifically for cell detection.Experiments show that the system is able to detect the thickness of cell and molecule quickly dynamically and non-contact.The accuracy of this system is several microns. |
