Direct and reflected light are captured by nested photodetectors to extend flow cytometer dynamic range without increasing chip area.

A fluorescence reference and small reaction chamber enable fast, low-volume coagulation testing with reliable optical detection at the point of care.

A partitioned pressure cell isolates biological samples from the pressurizing fluid while enabling light scattering measurements up to 350 MPa.

Ratio-metric modulated light separates smoke reflections from ambient light noise, improving chamberless detector sensitivity and reducing false alarms.

A second light sensor measures ambient light so the control circuit can filter noise from smoke-scatter signals and improve chamberless detector sensitivity.

Three spherical relay mirrors deliver a diffraction-limited image for smaller wafer defect detection while reducing aberrations, stray light, and cost.

A variable mirror and harmonic-generated EUV beam let one inspection setup switch among ptychography, scatterometry, and reflectometry.

A pinhole mirror splits incoming light by radial position to feed image and reference sensors with fewer optical parts and lower cost.

Electromagnetic reflectance scanning detects aflatoxin in edible seeds quickly and non-destructively, reducing waste while meeting food safety limits.

Multiple reader orientations and a reference sensor improve lateral flow assay accuracy while keeping liquid sample testing low cost.

Multi-wavelength fluorescence and backscatter analysis automates blood cell counting and differentiation without manual high-magnification review.

A baseline-calibrated optical sensor tracks dialysate turbidity changes and filters noise to alert peritonitis earlier during PD.

Time-variable illumination synchronized with rolling-shutter scan settings suppresses dominant surface reflection and reveals subsurface structure.

Separating time-varying signals into individual particle components reduces coincidence errors and improves size and velocity measurement in dense sprays.

Alternating protrusions and recesses steer illumination away from the detector while preserving useful scattered light for stable smoke sensing.

Multiple beam emitters in one smoke detector expand reflector paths to cover large areas with fewer transceiver units and lower system complexity.

Projected structured light boosts contrast on transparent, translucent, and opaque surfaces to reveal interfaces and micron-scale features non-destructively.

Diffused backlighting from below boosts NIR light reception through transparent objects, improving plastic material identification accuracy.

Visible and 850 nm light with CMOS sensing measures recording material moisture accurately while avoiding costly InGaAs optical components.

Optical sensing tracks actual filter dirtiness and adjusts cleaning alerts to avoid fixed schedules that can hurt heat dissipation.

A two-axis mirror and ellipsoidal mirror capture BRDF across multiple angles without moving the light source or detector.

Combined scattered and diffracted light detection distinguishes contaminants from pinholes on transparent films in one faster inspection step.
