产品简介:
The OPTIPHASE (R) OPD-4000 is the world’s leading instrument for high-precision interferometric measurement applications.Developed by experts in the use of fiber based interferometry, the OPD-4000 delivers previously unattained levels of cost-effective performance and ease-of-use for a wide variety of applications. The OPD-4000 is a simple yet powerful instrument for measuring interferometric phase. The unique and patented digital process provides for simultaneous low noise and high dynamic range operation. For anyone designing, developing or using a fiber-based interferometer, there is no better way to get faster, easier and more cost effective measurement results.The OPD-4000 is a DSP based large-angle optical phase demodulator. It performs demodulation of interferometers that can accommodate Phase Generated Carrier [PGC]modulation [see chart below]. Through precise monitoring of the received optical signal, the OPD-4000 automatically determines the proper parameters for gain-optimizing the receiver signal, stabilizing modulation depth at π radians and sampling phase for accurate quadrature signal extraction. Optical phase is determined through inverse trigonometric functions and dynamic range is enhanced via fringe counting. The measured optical phase is a 32 bit word updated once per modulation cycle. Output formats are digital [USB 2.0] and 20 bit analog.A Polarization Diversity Receiver is available for those needing to address polarization fading.The OPD-4000 ships with PhaseViewTM software, a powerful MS Windows based userinterface for easy set-up and data transfer. Whether you are conducting research and development, designing photonic components or sensor systems, the OPD-4000 will serve asan indispensable tool in all your applications. Outside the R&D arena the OPD-4000 is a powerful productivity tool reducing labor and material costs in quality assurance testing,industrial process controls or service and repair operations.The OPD-4000 has no commercial equivalent as a general-purpose interferometric phase measurement instrument. With the user-friendly PhaseView? software and indicators for input signals and modulation levels, the user is free to perform the task of taking criticalmeasurements.
