The present invention relates to an apparatus and to a method of load dependent analyzing an optical component ( 114 ), comprising the steps of: splitting an initial signal ( 115 ) into the reference signal ( 115 b) into and into a measurement signal ( 115 a), intermittently providing a load signal ( 108 ) to the component ( 114 ), providing the measurement signal ( 115 a), to the component ( 114 ),so that the component ( 114 ) can influence the measurement signal ( 115 a) to create a signal ( 120 ) influenced by and received from the component ( 114 ), superimposing the reference signal with the signal ( 120 ) received from the component ( 114 ), to provide a superimposed signal ( 118 ), detecting the superimposed signal ( 118 ) when the loading signal ( 108 ) is not present at the component ( 114 ) to provide an information containing signal ( 126 ), and processing the information containing signal ( 126 ) to determine an optical property of the component ( 114 ) dependent on a property of the load signal ( 118 ). |
