Aurora fNIRS - NIRSport 2 Acquisition software. How acquire data with NIRS?

Aurora fNIRS takes a whole new approach to user instrument control and data acquisition. With it, NIRx delivers intuitive, flexible, and easy-to-use software for the portable NIRSport 2 fNIRS solution.

Aurora fNIRS connects to your NIRSport 2 device(s) via Wi-Fi or USB, and can set-up a complete experimental configuration in only several clicks. Thanks to the automated signal signal optimization algorithm, Aurora fNIRS ensures optimal signal quality before a measurement is started. Raw data, HbO and Hb concentration changes can be visualized in real-time in several display modes. In addition, high-end whole-head visualizations are immediately available. Recorded data can be exported over the integrated Lab Streaming Layer (LSL) protocol, allowing for real-time processing in Brain-Computer Interface (BCI) and Neurofeedback paradigms.


The modified BeerLambert law parameters that will be used for the online computation of oxygenated and deoxygenated hemoglobin is shown in the image below.

Again, these parameters are only used for online data visualization and will not affect the data stored by Aurora. Aurora always stores raw voltage data (V).

Please follow the steps below in order to install Aurora fNIRS

1. Run the Aurora fNIRS Installer. Confirm that the application is allowed  to make changes to the device if this is requested by Windows.

2. Follow    all steps   until installation    is complete. It is recommended to choose the default installation folder.

3. Complete  the installation  by clicking the Finish  button. Note: Please refer  to the next section “Device Setup” before  running the software.

4. Upon  first running  Aurora fNIRS, make  sure the software is allowed full network access by configuring Windows Firewall.

The NIRSport2 device can connect to Aurora fNIRS either via USB or via Wi-Fi. Regardless of mode, ensure that the device is powered on by holding the power button for several seconds.  A bright green light will indicate the device is turned on.

Note  that NIRSport2  battery does not  charge while data acquisition.  Make sure that the device is fully-charged before running a measurement.

Connect the NIRSport2 device to the PC running Aurora with the provided USB cable. When the device is connected via USB for the first time Windows will automatically download and install the necessary drivers. A working internet connection is needed at this time.
