Innovation Summary:
This invention is a high-speed optical delay line system that provides linear, true time delays using a unique curved mirror geometry. The system includes input/output optics and a reflective surface centered about an evolute curve, enabling retro-reflection of light along a beam path tangent to the curve’s edge. This design allows for precise control of optical delay without distortion or dispersion, making it ideal for high-repetition-rate optical systems. The architecture supports compact, scalable implementation and is well-suited for integration into advanced photonic and RF systems.

Challenges / Opportunities:
Conventional optical delay lines often suffer from nonlinear delay characteristics, limited bandwidth, or bulky configurations. This invention addresses these limitations by offering a compact, linear delay solution that maintains signal integrity at high speeds. It opens opportunities in phased-array antenna systems, optical signal processing, and ultrafast spectroscopy, where precise timing and minimal distortion are critical.

Key Benefits / Advantages:
✔ True time delay with linear response
✔ High repetition rate compatibility
✔ Compact and scalable optical architecture
✔ Minimal signal distortion and dispersion

Applications:
• Phased-array radar and communication systems
• Ultrafast optical signal processing
• Time-domain spectroscopy
