NinjaNIRS is a modular and portable functional near-infrared spectroscopy (fNIRS) device designed for high-density, whole-head brain activity monitoring. It supports up to 200 optodes, with a maximum of 56 sources and 144 detectors, capable of dual-wavelength fNIRS data acquisition, enabling detailed mapping of brain activity. ninjaNIRS2024: Hardware documentation here. ninjaNIRS2022: Hardware specifications here. The journal paper describing the system is published in Biomedical Optics Express at https://doi.org/10.1364/BOE.531501. ninjaNIRS2021: Hardware specifications here. Samuel West has described a simple arduino based trigger box to add to ninja21 in the forum here. ninjaNIRS2020: Hardware specifications here. Poster we presented at SPIE Photonics West in 2019. Our January 2017 prototype to test noise level and dynamic range is described here.
