Photometry Using Reference Value TRIZ Cases
- Temperature Compensation Circuit for LED Radiant Energy Stability
A weighted current adder combines temperature-dependent and independent currents to regulate LED drive signals.
- Non-contact Optical Insertion Loss Measurement for Fiber Connectors
A non-contact method measures optical insertion loss by axially aligning fiber ferrules with a defined gap and extrapolating values to zero distance.
- Optical Filter for Backlight Brightness Uniformity
A spatially varying optical filter replaces complex drive electronics to eliminate local hot spots and achieve uniform backlighting.
- Electro-active Optical Phantoms for Biomedical Imaging Calibration
Embedded electro-active devices modulate phantom opacity to mimic hemodynamic responses, replacing bulky fluidic controls with electronic voltage signals.
- Laser Diode Power Calibration for Conducted Electrical Weapons
A laser diode calibration system adjusts optical output power using a golden voltage reference and duty cycle modulation to maintain precise illumination levels.
- DMD Modulation for Geiger Mode APD LIDAR Sensitivity Uniformity
A digital micromirror device deflects light paths to mask dead or hot detectors, reducing noise and crosstalk in the sensor array.
- Light-emitting Element Driving Circuit with Auxiliary Potential Control Unit
Auxiliary potential control unit accelerates capacitor charging during start-up to reduce initial delay and speed up Auto Power Control operations.
- Body Fluid Measurement Device Light Intensity Stabilization
A body fluid constituents measurement device stabilizes light intensity using ambient temperature data and dynamic pulse adjustments.
- Memory Thyristor Array for LED Print Head Control
Sequentially shifting an ON state across switch elements synchronizes LED lighting, reducing intensity variations that degrade image formation precision.
