    • Dual-pupil, dual spectral band wide field-of-view re-imaged refractive optical imaging systems. In one example an optical imaging system includes a dual-band front objective lens group configured to receive electromagnetic radiation over the field-of-view of the optical imaging system, to form a first pupil, and to direct the electromagnetic radiation through the first pupil, the electromagnetic radiation including first and second non-overlapping spectral bands, and the field-of-view spanning at least 45° x 45°, and a re-imaging refractive optical sub-system configured to receive the electromagnetic radiation via the first pupil, to form at least one intermediate image plane, and to focus the electromagnetic radiation via at least one second pupil onto at least one final image plane to form a first image from the first spectral band and a second image from the second spectral band. A beam deflector can be positioned proximate the first pupil to expand the field of view.

    • An optical system for panoramic stereoscopic imaging can include an outer reflector and an inner reflector, which can both be configured to reflect light to a camera. The outer reflector can include striations or other reflection elements to turn the light that is reflected to the camera such that first and second light rays that are parallel and offset from each other (e.g., suitable for stereoscopic 3D viewing) can be reflected by the respective outer and inner reflectors to the camera. The outer reflector can be partially reflective and partially transmissive so that some light can pass through the outer reflector to be reflected by the inner reflector to the camera. The camera can capture a single image having a first portion that corresponds to a view generated by the inner reflector, and a second portion that corresponds to a stereoscopically offset view generated by the outer reflector.

    • A system for forming an image (110) of a substantially translucent specimen (102) has an illuminator (108) configured to variably illuminate the specimen from a plurality of angles of illumination such that (a) when each angle (495) at a given point on the specimen is mapped to a point (445) on a plane (420) perpendicular to an optical axis (490), the points on the plane have an increasing density towards an axial position on the plane. A detector is configured to acquire a plurality of variably illuminated, relatively lower-resolution intensity images ( 104) of the specimen based on light emitted from the illuminator according to variable illumination and filtered by an optical element (109). A processor is arranged to computationally reconstruct a relatively higher- resolution image of the specimen by iteratively updating overlapping regions (1005) of the relatively higher-resolution image in Fourier space (Fig. 10B) with the variably-illuminated, lower-resolution intensity images.
