Material Analysis By Optical Means TRIZ Cases

Pressure sensors and an adjustable fan maintain the tool's pressure difference, reducing aberration instability during EUV mask inspection.

Using 30%, 60%, and 90% curve points, the method distinguishes lupus anticoagulant, factor deficiency, and inhibitor patterns.

Selective optical coatings redirect remaining light to receivers, reducing light loss and improving biometric signal accuracy in rings.

Dome-shaped reflectors and annular light sources support multiple inspection axes while improving illumination uniformity and accuracy.

A closed-loop gas detector visualizes concentration with visible light, then adjusts infrared position for stronger analysis accuracy.

In-situ scribing maps rock strength while near-infrared spectroscopy measures water content for systematic tunnel rock grading.

Brief illumination pulses synchronized with camera exposures collect photons while limiting motion blur across multiple images.

This measuring device passes selected diffracted light to image periodic marks, reducing wave-aberration effects during exposure alignment.

Parallel micro-cameras and refocusing support high-throughput 2D and 3D inspection of non-planar surfaces.

A modified Herriot cell splits one beam across two path lengths and detectors to measure trace gases over a high dynamic range.

Dual collinear optical paths and LED wavelength selection reduce drift, filter variation, and power demands in gas sensing.

Separate collection and imaging solutions preserve blood samples while improving buffy coat clarity and reducing analysis variability.

A higher-reflectance first reflector and lower-reflectance side areas clarify transparent waste images while reducing contamination risk.
