Optical Detection TRIZ Cases

Dynamic infrared intensity adjustment and temperature calibration cut pest detection errors while using one emitter-receiver pair.

Parallel time-slot scheduling lets one optical sensor serve multiple measurement clients while preserving scan flexibility, speed, and accuracy.

Sensor fusion across radar, thermal, PIR, and environmental inputs improves presence detection accuracy while reducing false positives.

Visible alignment beams and retroreflective targets simplify multi-beam light barrier setup while improving robustness to laser misalignment.

Dual diagonal emitters and receivers compare thickness at two positions to detect overlapping objects despite debris, EMI, and non-flat shapes.

Timed sampling at peak reflected light improves SNR, cuts false detections, and supports accurate weight sensing in bioptic barcode readers.

Color-based light calibration keeps aerosol stick sensing accurate while limiting optical sensor aging from heat and continuous emission.

Multi-wavelength reflected-light trends distinguish skin from non-skin contact, improving wearable wearing-state accuracy while cutting power use.

Infrared emitters and photodiodes detect pest wingbeats automatically while PWM cuts power use and filtering reduces false positives.
