Kernel Flow uses near-infrared spectroscopy with 52 photon modules (each containing one laser and six sensors firing in ~100 picoseconds) to measure blood oxygenation changes in the cortex, with approximately 1,000+ channels sampling brain activity in real-time without requiring laboratory settings or surgical implants.

Evidence Quote

there's 52 modules and each module has one laser and six sensors...we sense those photons and then we do the reconstruction for the activity overall there's about a thousand plus channels that are sampling your activity
