Photometry Using Electric Radiation Detectors TRIZ Cases
- Lens-Based Laser Power Sampling for Compact Beam Monitoring
A curved partially reflective lens samples and focuses laser light for accurate power monitoring without added optical complexity or beam-path changes.
- Laser Fiber Fuse Detection Using Backward Visible-Light Monitoring
Backward visible-light monitoring through a coupled fiber enables earlier fiber fuse detection with one receiver and fewer false near-IR triggers.
- Coherent Beam Combining Using Calibration Laser Phase Control
A separate-wavelength calibration laser sets beam phase before high-power startup, enabling coherent combining despite switching fluctuations and turbulence.
- Processing Chamber Lamp Radiation Monitoring for Aging Compensation
Radiation sensors track zone-level lamp output over time, enabling early aging alerts and power adjustment in processing chambers.
- Nano-Textured Attenuator for High-Power Laser Beam Profiling
Nano-textured beamsplitters attenuate high-power laser beams to camera-safe levels for accurate profiling without thin-film damage.
- Plasmonic Infrared Detector Structure for Fast SWIR Absorption
Embedded metal nanostructures boost SWIR absorption in a thin infrared detector, enabling faster operation with lower dark current and parasitic impedance.
- Magnetic Photodetection Element With High-Thermal-Conductivity Layer
A high-thermal-conductivity layer draws heat from a magnetic photodetection element, improving heat dissipation during light exposure.
- Integrated LED and Photosensor Layout for Precise Brightness Control
An on-substrate photosensitive element detects LED side light directly, improving brightness calibration accuracy and reducing external noise.
