Matched Lengths of S and P Paths
The INT-POL-1300 is an integrated pair of balanced detectors that are used to analyze the S and P States of Polarization (SOP) of two input signals independently. This compact system is designed for polarization sensitive optical coherence tomographyy (OCT) applications, but it can be used in any application where the difference between two signals has to be analyzed with high sensitivity.
主要特点：
Functionality of Balanced Receivers
The S and P polarization states of the input are split using a polarization beamsplitters (PBS). The split inputs are directed into two balanced detectors, one for each SOP. These balanced photodetectors operate in the same manner as our PDB100 Series of OCT Balanced Detectors, they subtract the two optical input signals from each other resulting in the cancellation of common mode noise. This allows small changes on the signal path to be extracted from the interfering noise floor for each SOP.
