1. An imaging system, comprising:
a first camera configured to capture a first set of oblique images along a first scan path on an object area;
a second camera configured to capture a second set of oblique images along a second scan path on the object area;
a scanning mirror structure including at least one mirror surface; and
a drive coupled to the scanning mirror structure and configured to rotate the scanning mirror structure about a scan axis based on a scan angle, wherein
the first camera has an optical axis set at an oblique angle to the scan axis and includes a lens to focus a first imaging beam reflected from the scanning mirror structure to an image sensor of the first camera,
the second camera has an optical axis set at an oblique angle to the scan axis and includes a lens to focus a second imaging beam reflected from the scanning mirror structure to an image sensor of the second camera,
at least one of an elevation and azimuth of the first imaging beam and at least one of an elevation and azimuth of the second imaging beam vary according to the scan angle,
the image sensor of the first camera captures the first set of oblique images along the first scan path by sampling the first imaging beam at first values of the scan angle,
the image sensor of the second camera captures the second set of oblique images along the second scan path by sampling the second imaging beam at second values of the scan angle,
the at least one mirror surface includes a first mirror surface and a second mirror surface that is substantially opposite the first mirror surface, and
the first imaging beam is reflected from the first mirror surface and the second imaging beam is reflected from the second mirror surface.
