Interferometric Spectrometry TRIZ Cases
- Tuneable Fabry-Perot Cavity Self-Calibration via Calibration Filter Film
Calibration filter films provide fixed wavelength references that correct voltage control curve drifts in tuneable Fabry-Perot cavities.
- Lock-in Image Detector for Phase Measurement in Lithography
A lock-in image detector captures amplitude and phase information of diffracted radiation using optical frequency shifting.
- Interference Film Layer with Variable Thickness for Spectrometer Miniaturization
A variable-thickness interference film layer replaces moving mirrors and beam splitters to eliminate mechanical complexity in Fourier spectrometers.
- Interferometric Near-Infrared Spectroscopy System for Brain Tissue Analysis
An interferometric near-infrared spectroscopy system uses dual wavelength-swept light sources and a common sample delivery channel to detect brain tissue signals.
