Selfoc lenses and their application to optical fiber sensing system

Based on the analysis of optical properties of Selfoc lenses, error reasons are analyzed in details to cause coupling losses between Selfoc lenses such as lateral misalignment , angular mis-alignment ,end spacing and mounting error and chromatic aberration ,and the application of Selfoc lenses to the optical fiber sensing system is introduced. A compensating structure is proposed so as to improve the measurement accuracy and stability of the optical fiber sensing system. It reaches a better compensating result.
