Phase-Affecting Property Measurements TRIZ Cases

Different fringe orientations encode six holographic channels in one exposure, improving spatial bandwidth efficiency for dynamic samples.

Phase-randomized phased arrays speed precise measurement of dense lithographic features.

This case integrates refractive index sensing into the droplet gap, using waveguides to limit stray light and simplify optical measurement.

A single source and detector route beams through multiple fluid cells, reducing component redundancy, size, weight, and cost.

Deposits can impair readings, so an extendable rotating wiper cleans the measuring window in situ without opening the fluid channel.

Pupil-plane modulation adjusts illumination transmittance to improve phase and 3D refractive-index measurement accuracy in microscopy.

This case calculates irradiation fields from 3D surface data to plan illumination paths and improve complete flaw inspection coverage.

A defocused image is backpropagated to reconstruct surface maps with expanded dynamic range across high- and low-reflectivity regions.

Pinhole and open-path scans are merged to filter diffraction orders and improve refractive index profile accuracy.

A time-independent ray-equation index guides neural-network calculations of refractive index distributions from complex light paths.

Acoustic waves align flowing cells in one plane while low-finesse Fabry-Perot fringes support cost-effective physical characterization.

A spatially varying liquid crystal alignment pattern creates resonance wavelengths for simpler refractive index sensing.

Broadband reflection profiles and nonlinear fitting reveal porous-layer thickness, porosity, and roughness on non-flat substrates.

Dual-bandwidth terahertz sensing measures object dimensions and detects defects.

This case uses sensor readings from soaking-solution components to determine bean permeation and select a suitable soaking endpoint.

Multiple fixed light paths replace mechanical adjustment, enabling fast optical density measurements across varying solution concentrations.

Wavelength-selecting apertures quantify deflection angles, refractive index, and scattering.

Reflected terahertz waveforms and iterative modelling estimate layer thickness and refractive index in highly absorbing samples.

MOF nanopores and time-dependent signals improve VOC selectivity beyond equilibrium-only gas sensor responses.

A compact probe uses a measuring prism and optical fibers to keep sensitive optics remote while measuring refractive index in hot processes.

Reduce speckle noise in biomolecule detection with low-coherent light and dispersive elements.

Multiple reflected-light spots map refractive index across conveyed polymer film, improving cross-width thickness measurement accuracy.
