Optical Rangefinders TRIZ Cases
- Dense Chromium Sputter Coating for Oxidation-Resistant Substrates
Controlling ion-to-chromium flux and substrate bias in magnetron sputtering forms dense chromium layers that improve oxidation resistance.
- Stereo Camera Parallax Estimation Beyond Overlapping Views
Past parallax and road-height data let a stereo camera estimate moving-object distance in monocular views despite changing road levels.
- Dynamic Sideband Locking for Variable Synthetic Wavelength Ranging
Dynamic sideband locking enables continuous synthetic wavelength tuning for absolute distance interferometry with high accuracy over long ranges.
- Hermetic LiDAR Transmitter Module for Stable Optical Alignment
A sealed LiDAR transmitter integrates the laser, driver ICs, and optics to cut parasitic inductance, prevent contamination, and hold alignment.
- SPAD Control Circuit for Shorter Dead Time and Wider Dynamic Range
Multiple SPAD supply paths shorten dead time and expand dynamic range, enabling reflected-light detection at shorter intervals.
- Stacked Pixel Signal Paths for Fast HDR Photoelectric Control
Separate pixel signal paths on stacked substrates speed control generation while preserving SNR for wide dynamic range imaging.
- Moving Object Material Identification via Multi-Wavelength Point Clouds
Multi-wavelength point cloud processing identifies moving object materials in real time while avoiding complex multi-receiver alignment.
- VCSEL Electrode Layout for High-Speed Independent Emitter Switching
A stacked VCSEL structure with tunnel junctions and separated emitters enables faster switching, lower IC count, and tighter emitter spacing.
- Laser Light Source Control for Uniform Spot Detection
Image-sensor feedback adjusts laser emission power, timing, and pulse count to equalize spot luminance and improve coordinate detection.
- VCSEL Light Source Pulse Control for Thermal-Stable Exposure
Multiple short VCSEL emissions within one frame maintain exposure while limiting heat rise, preserving luminous efficiency and sensing precision.
