1. A system for capturing aerial images, the system comprising: two steerable detail camera modules, each steerable detail camera module comprising a detail camera and a first beam-steering mechanism, a pointing direction of the detail camera being time-multiplexed by the first beam-steering mechanism to sweep out a wider effective field of view along a steering axis, the first beam-steering mechanism comprising a first steerable mirror tilted with respect to an optical axis of the detail camera module, the first steerable mirror being configured to spin about the optical axis of the detail camera module to effect beam steering, the steering axes of every detail camera module being angularly distributed substantially 90 degrees apart from each other and angled at substantially 45 degrees to a direction of flight, each detail camera module being configured to sweep out a field of view between an extreme right oblique angle and an extreme left oblique angle.
