Interferometers TRIZ Cases
- Holographic Interferometer Superpixel Phase Extraction for Fast Scanning
A tilted reference beam and superpixel analysis extract phase from one image, enabling fast scanning with uniform line density.
- Optical Interferometer Ferrule Layout for Accurate LIDAR Velocity
Tilted Fabry-Perot etalon surfaces can distort velocity projections; symmetrical ferrule emitters equalize paths and limit interference.
- OCT Scanning Fiber Synchronization for Motion-Artifact Control
A phase-aware trigger aligns OCT A-line acquisition with slow probe motion, preserving lateral resolution during integrated RGB imaging.
- Lithium Niobate Mach-Zehnder Modulator Bias Control with Analog Feedback
Photocurrent comparison adjusts bias voltage to hold the quadrature point, reducing distortion and bit errors with simple analog control.
- Long-Range Optical Frequency-Domain Reflectometry Using Delayed Local Light
A delayed local-light fiber and 90-degree hybrid support measurements beyond 1 km while preserving 100 µm spatial resolution.
- Dual SMI Sensor Measurement for 3D Object Length and Speed
Opposite-direction SMI beams distinguish objects from transport media while measuring length and speed at variable rates.
- Dual-Mode OCT–OCM Imaging With Afocal Relay Pupil Control
An afocal relay switches OCT and OCM modes while holding pupil positions steady, avoiding sample repositioning and image distortion.
- Three-Dimensional Measurement Device Without Quarter-Wave Plate Errors
This 3D measurement case uses distinct light directions and wavelengths to simplify interferometer optics and extend measurement range.
- Optical Interface Interferometry for Simultaneous Assembly Measurement
Low-coherence interferometry combines multiple reference beams to capture interface shape, tilt, and decentring in optical assemblies.
