Based on the wide-angle imaging apparatus of the objective lens of concentric spheres

The present invention relates to an image forming apparatus based on the wide-angle lens of concentric spheres, comprising: concentric spherical lens, an objective lens having a field of view; Small Field field mirror system, comprising: a probe corresponding to the imaging side of the field lens and the field lens ; a field lens optical axis passing through the center of the sphere concentric spherical lens; field is a field lens portion of the field of view of said objective lens; and sweeping swing mechanism, the swing mechanism so that the sweep field mirror Small field the system of concentric rotation about the spherical center of the spherical lens; sweeping said swing mechanism having at least two scanning position; wherein said field mirror system Small field obtain the at least two positions at least two scanning image acquisition of the sub-images, said at least two sub-images obtained after a single frame of full image stitching. Wide-angle imaging apparatus according to the present invention, a compact structure, having a wide field of view imaging range.
