Holographic Air‐Quality Monitor (HAM)
Indoor Air, Volume 2024, Issue 1, 2024.We introduce the holographic air‐quality monitor (HAM) system, uniquely tailored for monitoring large particulate matter (PM) over 10 μm in diameter—particles critical for disease transmission and public health but overlooked by most commercial PM sensors.
