Ellipsoid Droplet Sensor Uniform Detection

The patent employs an ellipsoidal optical element with a specific curvature profile defined by the equation x²/a² + y²/b² + z²/c² = 1. This curved surface geometry enables uniform light reflection across the detection area, achieving consistent detection sensitivity while maintaining manufacturability through standard molding techniques for curved surfaces.

The patent optimizes specific geometric parameters of the ellipsoid (semi-axes lengths a, b, and c) to achieve uniform detection sensitivity. By carefully selecting and adjusting these parameters, the patent achieves both uniform detection performance and ease of manufacture through standard fabrication processes.

The ellipsoidal shape with its mathematically defined curvature allows the optical element to maintain a relatively simple geometric form while providing a large effective detection area. The smooth continuous surface of the ellipsoid avoids complex features that would difficult to manufacture, enabling both large coverage and manufacturing precision.

The ellipsoidal optical element serves multiple functions: it reflects light uniformly across a large detection area, maintains structural integrity, and can be manufactured using standard processes. This multi-functionality allows the single component to achieve both large detection area and manufacturing simplicity.
