Self-mixing interferometry feedback loop: DysonRecent Research Landscape

Unstable airflow in motor assemblies causes mechanical wear and energy inefficiency. This lever utilizes laser backscatter modulation to provide real-time velocity data for precise motor speed adjustment.

What technical problems is Dyson addressing in Self-mixing interferometry feedback loop?

Inaccurate airflow rate measurement

(14)evidences

Internal obstructions and motor variations cause unpredictable air volumes. Precise monitoring prevents motor burnout and ensures consistent air purification performance.

Optical feedback instability

(4)evidences

Uncontrolled fluctuations in the laser cavity caused by backscattered light lead to signal distortion and measurement inaccuracy. Stabilizing this feedback loop ensures precise displacement and velocity sensing.
