Fiber-reinforced SiC composite layers and monolithic SiC improve fuel cladding toughness, hermeticity, and crack resistance.

Downsampling a 2D pixel grid into 1D dot-trail vectors combines time-of-flight and triangulation to simplify detection and improve depth accuracy.

Stored correction values address optical-axis misalignment and unequal optical paths that can distort ToF distance calculations.

Combining RGB depth estimation with i-ToF refinement reduces uncertainty and corrects de-aliasing errors in 3D distance measurements.

Aim-light distance detection lets a microprocessor coordinate variable focus, zoom, and illumination for compact long-range barcode scanning.

Two operating modes distinguish housing and laser-beam inclination, reducing confusion in handheld distance measurements.

A polarizing-beam splitter separates outgoing and returning LIDAR light with less optical loss, preserving weak-signal power for reliable data.

Replacing helium with a high-boiling liquid filler improves heat transfer and wicks into cladding cracks to protect nuclear fuel rods.

A pixel counts received logic pulses to adjust a pulsed light source, reducing power use while preserving distance-measurement accuracy.

An in-chamber transceiver scans PVD targets to measure erosion depth and profile without removal, supporting repeatable deposition control.

Simultaneous distance sensing locates and marks target points from multiple references, reducing laborious measurement steps.
