Interferometers TRIZ Cases
- Coherent Receiver Array On-Chip Interference
Integrated mirrors split optical signals for on-chip interference with photodetectors, eliminating mechanical scanning in OCT systems.
- Variable Step Height Grating Fields for Optical Positioning
Variable step heights in scanning plate grating fields optimize diffraction efficiency for single-wavelength optical position measuring devices.
- Optical Angle Sensor Using Diffractive Interferometry for Wavelength-Independent Detection
A diffractive optical angle sensor stabilizes combined light overlap at the receiver to maintain measurement precision.
- 1-Micron Microcomb OCT Axial Resolution via Silicon Nitride Resonators
Silicon nitride microresonators generate 1-micron frequency combs to achieve 5.6 μm axial resolution in biological tissue imaging.
- Triple Reflection End Reflector for High Numerical Aperture Interferometry
A triple reflection end reflector generates lateral shear between reference and object beams to create spatial interferograms.
- Multi-path Optical Interferometer Phase Extraction via Reference Signal
Polarization and frequency multiplexing generates a reference signal that resolves phase ambiguity in multi-path interferometers.
- Confocal Fabry-Perot Interferometer with Folding Mirror
A confocal Fabry-Perot interferometer uses a folding reflective surface to resolve mirror parallelism constraints, enabling sub-nanometer positioning accuracy.
- Optical Interferometer for Turbine Blade Tip Clearance Measurement
An optical interferometer measures blade tip clearance using interference patterns generated by reflected light.
- Laser Interferometric Motion Detection with Frequency Shift
A laser interferometric system detects surface motion by introducing a small frequency shift between reference and object beams.
