• Case Study: Breakthrough in Satellite Imaging Technology

    Jan. 29, 2024

    Overview

    In the realm of modern communication, Earth observation, and scientific research, satellites play an indispensable role. The optical systems utilized in on-orbit satellites are paramount for capturing high-quality images and data. However, designing optical systems for space applications presents numerous challenges, including size constraints, the necessity for a large field of view, and demanding relative aperture requirements that traditional optical designs struggle to address.

    Historically, coaxial systems were employed in satellites, but they faced limitations such as a restricted field of view, central obscuration, and diminished ideal transfer functions, rendering them inadequate for capturing comprehensive images of expansive areas. Conversely, off-axis systems, while offering a larger field of view, encountered challenges related to central obscuration and constraints on relative aperture. The imperative to develop an innovative optical system that could surmount these challenges became a pivotal goal in advancing satellite imaging capabilities.
