Abstract:
1. A system for capturing aerial images, the system comprising at least one double-field steerable detail camera module, the steerable detail camera module comprising: a detail camera; a first beam-steering mechanism configured to time-multiplex the pointing direction of the camera to provide a wider effective field of view along a first steering axis, the first beam-steering mechanism comprising a first steerable mirror tilted with respect to a first optical axis of the detail camera module, the first steerable mirror configured to spin about the first optical axis to effect beam steering; a second beam-steering mechanism configured to time-multiplex the pointing direction of the camera to provide a wider effective field of view along a second steering axis, the second beam-steering mechanism comprising a second steerable mirror tilted with respect to a second optical axis of the detail camera module, the second steerable mirror configured to spin about the second optical axis to effect beam steering; and a mechanism configured to switch the field of view of the detail camera between, and thereby selecting one of, the first and the second beam-steering mechanism.
