I. The Film Era: Optical Beginnings and the Limits of Spherical Lenses (Pre-20th Century–1940s)

In the late 19th century, the birth of aerial photography opened humanity’s first of Earth. Early reconnaissance cameras relied on traditional spherical lenses, but their imaging suffered from spherical aberrations, chromatic distortions, and bulky designs. For example, World War I-era "pigeon cameras" achieved resolutions of only a few meters, failing to meet battlefield reconnaissance needs.

II. The Space Age: The Rise of Aspherical Mirrors (1950s–2000s)

As the space race accelerated, aspherical optical technology achieved milestone breakthroughs. Aspherical mirrors, with their freeform surface designs, eliminated spherical aberrations and dramatically improved imaging quality and system efficiency:

Satellite Remote Sensing: The 1972 Landsat-1 satellite, equipped with aspherical optics, enabled 80-meter-resolution multispectral imaging, revolutionizing Earth resource monitoring.

Space Telescopes: The 1990 Hubble Space Telescope, featuring a 2.4-meter aspherical primary mirror, pierced through atmospheric interference to capture iconic deep-space images like the "Pillars of Creation," rewriting astronomical understanding.

III. The Digital Era: Dual Breakthroughs in Resolution and Lightweighting (2000s–2020s)

The 21st century’s demand for miniaturized spacecraft and deep-space exploration drove Optical System transformations, with aspherical mirrors emerging as the standard for their "high precision + lightweight" advantages:

Deep-Space Probes: The Mars Curiosity rover’s aspherical optical components enabled 1600×1200-pixel surface imaging and rock spectral analysis, aiding the search for signs of life.

Commercial Satellites: The WorldView-4 satellite utilized a 1.1-meter aspherical primary mirror to achieve 0.31-meter resolution, advancing high-precision global mapping.

Drone Imaging: Lightweight aspherical mirrors reduced drone electro-optical payload weight by 40%, enabling extended missions and real-time tracking.

IV. The Future: Fusion of Metasurfaces and Intelligent Imaging (2020s and Beyond)

Aerospace imaging is entering a new era of "lighter, smarter, and stronger" systems, with aspherical mirrors converging with frontier technologies:

Metasurface Technology: Harvard’s flat metasurface lenses could replace complex lens assemblies. We are exploring hybrid systems combining metasurfaces with aspherical bases.

Quantum Imaging: Building on the "Micius" satellite’s quantum communication, future systems may achieve unhackable deep-space links and ultra-sensitive imaging.

AI-Driven Optics: Deep learning algorithms dynamically optimize aspherical mirror parameters to correct atmospheric turbulence in real time, enhancing space telescope clarity.
