YINGCHI fNIRS — “Your Portable Optical MRI”
Near-Infrared Functional Brain Imaging System (fNIRS) infers neural activity by measuring hemodynamic changes in the brain. With simple operation, low cost, strong resistance to interference, and high compatibility, it is ideal for brain and cognitive neuroscience research in conventional laboratories, naturalistic environments, as well as for ward-based assessments and clinical brain function evaluation.
Multi-level quality control across hardware and software ensures signal accuracy and reliable mapping of brain activity. >>>
Features of YINGCHI fNIRS
Up to 224 Channels
Configurations support up to 64 sources × 64 detectors with flexible layout for whole-brain coverage.
Real-Time Spectral Monitoring
Physiological “fingerprints” of fNIRS—cardiac (~1 Hz) and respiratory (~0.25 Hz) rhythms—are verified in the frequency domain to support robust assessment of signal quality.
Short-Distance Channels
Removes superficial interference to recover clean cortical signals.
Concurrent Multimodal Physiological Recording
Respiration, pulse oximetry (PPG), heart rate variability (HRV), oxygen saturation (SpO?), temperature, galvanic skin response (GSR), and bipolar signals such as EMG and ECG are recorded to interpret brain function within the context of the whole physiological system.
APD Detectors
Avalanche photodiodes enable stable detection of weak hemodynamic signals, ensuring reliable data from deep cortical regions and low-activation tasks.
Dual-head Optode Design
Each optode features dual contact points to efficiently separate hair and ensure good scalp contact, reducing preparation time.
Adaptive Three-Stage Optical Probes
Automatically adapt to different hair conditions, ensuring signal quality independent of hair density.
Accelerometer
>9 axes (3 linear acceleration + 3 gyroscope + 3 magnetometer).
>Capture head movement to enhance fNIRS data validity, especially for research in naturalistic neuroscience and clinical populations.
3D Diffuse Optical Tomography (DOT)
Reconstructs three-dimensional hemodynamic changes across different cortical depths.
Lab Streaming Layer
Provides high-accuracy temporal alignment for multimodal brain imaging and brain–computer interface applications.
Acquisition & Analysis Software
User-friendly operation with real-time visualization, one-click reporting, and efficient data management.
Scientifically Designed Paradigms
Comes with built-in classical paradigms and also supports parallel testing and adaptive task difficulty, allowing flexible customization for diverse experimental needs.
Open-Source Software Compatibility
Data can be directly accessed and analyzed using third-party open-source platforms.
