Abstract

Curved imaging sensors bring significant size, weight and cost reduction to imaging systems while mitigating their off-axis optical aberrations. Unlocking these key features has captured the interest of major players of the imaging and semiconductor industry for the last two decades. Curved CMOS image sensors help to create compact imagers, telescopes and spectrographs. Recent research programs have demonstrated a reduction by a factor 2 of optical elements for wide field ultra-violet and visible Earth imagers, enhancing instrument image quality and signal to noise ratio. We illustrate the benefits brought by curved sensors for various applications, and present our on-going developments and technological roadmap.
