An ultra-highly sensitive LITES sensor based on multi-pass cell with ultra-dense spot pattern designed by multi-objective algorithm

Short summary

Researchers developed an ultra-highly sensitive Light-Induced Thermoelastic Spectroscopy (LITES) sensor using a novel multi-pass cell (MPC) with an ultra-dense spot pattern, achieving a minimum detection limit (MDL) of 4.78 ppb for acetylene.
