LSTM Deep Learning Enhances Optical Sensing for Biochemical and Medical Applications

Researchers have developed an LSTM-driven interferometric sensing system that achieves both high sensitivity and wide measurement range, overcoming previous trade-offs in optical sensing.
Key Details
- 1The LSTM model allows for accurate refractive index measurement beyond the free spectral range (FSR) limitation in optical interferometers.
- 2System architecture includes broadband light source, specially fabricated single-mode fiber, and spectral analyzer.
- 3Deep learning enables direct mapping of complex spectra to target measurements despite spectral overlap, tripling the detection range while retaining sensitivity.
- 4Efficient down-sampling reduces data acquisition and processing, making rapid, practical deployment feasible.
- 5Application relevance spans physics, chemistry, biology, and medicine—enabling real-time, high-precision monitoring in complex environments.
