1. Safety
The advisory words Danger, Warning and Caution used in this manual identify the level of hazard
that may be encountered by the user.
• DANGER means if the danger is not avoided, it will cause death or serious injury.
• WARNING means if the warning is not heeded, it can cause death or serious injury.
• CAUTION means if the precaution is not taken, it may cause minor or moderate injury.
Warning
The protection provided by the equipment may be impaired if the equipment is used in a
manner not specified by the manufacturer, resulting in serious injury or death.
The power cord is the main electrical disconnect for this equipment. If it is necessary to
ensure no power to the unit, remove the power cord.
The use of controls, adjustments, performance, or procedures other than those specified
herein may result in hazardous laser radiation exposure and one or more safety protections
may be impaired or rendered ineffective.
Attention
La protection fournie par l'équipement peut être compromise si l'équipement est utilisé
d'une manière non spécifiée par le fabricant, entraînant des blessures graves ou la mort.
Le cordon d'alimentation est le principal disjoncteur électrique de cet équipement. S'il est
nécessaire de ne pas mettre l'appareil hors tension, retirez le cordon d'alimentation.
L'utilisation de commandes, d'ajustements, de performances ou de procédures autres que
celles spécifiées ici peut entraîner une exposition dangereuse au rayonnement laser et une
ou plusieurs protections de sécurité peuvent être altérées ou rendues inefficaces.

3. Overview
The Luna POD 2000 is an advanced polarimeter powered by digital signal processing (DSP). It is
specifically designed for high-speed polarization characterization, analysis, and monitoring of light
beams. With its four-channel configuration, this instrument can simultaneously acquire the four
Stokes parameters, allowing precise measurements of the instantaneous state of polarization (SOP)
and degree of polarization (DOP).
The POD 2000 features a USB 2.0 interface, enabling direct data transfer to a computer. This allows
users to conveniently access and process the measured data on a computer for further analysis. The
polarimeter supports a high sampling rate of up to 100 KS/s, ensuring accurate monitoring and
analysis of fast polarization changes in real time. Additionally, it provides a standard 100BASE-TX
Ethernet interface, allowing for measurement and control over a network.
The POD 2000 is equipped with a user-friendly interface that offers real-time graphic displays of the
polarization state. Two display options are available:
Poincaré Sphere Window: This window presents the polarization state as traces on a Poincaré
Sphere, providing a visual representation of how the SOP changes over time.
Oscilloscope Window: This window allows users to monitor polarization changes over time, akin to
observing waveforms on an oscilloscope. It offers a dynamic view of the polarization state,
facilitating the observation of temporal variations.
This document serves as a comprehensive guide for setting up and using the application software of
the POD 2000. For instructions on properly setting up the hardware, please refer to the POD 2000
Quick Start Guide.
Note: The POD 2000 Quick Start Guide provides detailed information on hardware setup, which
should be followed to ensure proper installation and operation
There are 2 configurations available:

4. Hardware and Physical Setup
4.1. Unpacking
Inspect the POD-201 for any physical damage resulting from shipping and transportation. If any
damage is found, please contact the carrier immediately. Additionally, carefully review the packing
list to verify if any parts or accessories are missing. This information is crucial for the user manual.

4.2. Communication Connection
4.2.1. USB Communications
To communicate with the POD-2000 over an USB connection, connect a USB cable with a USB-B
male connector to the USB-B female connector on the back panel. The other end of the USB cable
must then be directly connected to the PC. The cable cannot be connected to an external USB hub
as it would performance issues when streaming measurement data to the PC.
4.2.2. Ethernet Communications
To communicate with the POD-2000 over an Ethernet connection, connect a Cat-5e or greater cable
to the Ethernet female connector on the back panel (distinguished with the tab pointing down). Be
careful not to connect to one of the two LVDS female connectors (distinguished with the tab
pointing up).
The other end of the cable can then be connected to an Ethernet router that a host PC is also
connected to or be connected directly to a PC. When connected to an Ethernet router, the POD-
2000 will have the static IP address of 192.168.1.150 by default. Please refer to the SCPI commands
section, on how to change the IP address or enable dynamic IP addressing.
When connecting directly to a PC, one must set the IP address strategy to DHCP to allow the POD-
2000 to acquire a link-local IP address.
4.3. Starting the system
To start the system, press the power button on the front panel. The power button will light. The
system is ready for the communication.
4.4. Shutting the system down
To turn off the system, press and hold power button for about 0.5 second. If the system does not
begin to shut down, press and hold the power button for about 2 seconds to force the system to
turn off.
