TECHNOLOGY LICENSING OPPORTUNITY: Multi-Channel Atomic Magnetometer (MCAM)

The Multi-Channel Atomic Magnetometer (MCAM) is a non-cryogenic, multi-channel optical quantum sensor that captures ultra-faint biomagnetic signals from the brain, heart, and other sources. The technology has a sensitivity approaching that of cryogenic SQUID-based systems and delivers performance at roughly one-tenth the per-channel cost without the need for liquid helium. The MCAM module operates on the spin-exchange relaxation-free (SERF) regime and uses a shared vapor cell, a single pump beam, a single probe beam, and a single detector array to generate multiple independent sensing channels. The technology has various market applications, including medical diagnostic imaging, pediatric and adaptive neuroimaging, micro-scale biomagnetic imaging, cancer diagnostics, magnetic resonance imaging, sensing, and instrumentation. • The MCAM module is engineered for arrays and can be tiled into a conformal helmet or surface array that adapts to head or torso shape. • The design is compatible with several alkali-metal and buffer-gas options and with per-module bias coils that allow each module to be tuned individually inside a larger array. • The technology has a development path toward micrometer-scale spatial resolution, which would extend the platform from whole-organ mapping into micro-scale magnetic imaging regimes. • The MCAM module is scalable into helmet-style arrays of hundreds of channels, including a size-adjustable pediatric configuration. • The technology has a shorter sensor-to-source stand-off via rear-mirror beam folding, sharpening spatial resolution of biomagnetic sources.
