An adaptive scanning optical microscope has a scanner lens assembly for acquiring images from different parts of an object plane and for forming a preferably curved image field having at least some aberration which varies as a function of the part of the object plane from which the image is acquired. A steering mirror selects the field of view and steers light from the object and along a light path from the object plane to a final image plane. An adaptive optics element receives the steered light from the object and compensates for the field position dependent optical aberrations and additional optics are along at least part of the light path for conditioning and focusing the light as it moves from the steering mirror, past the adaptive optics element and to the final image plane.

Adaptive-scanning optical microscope

A system for positioning an object about a remote center of rotation. A non-movable part provides a stationary reference structure. A movable part moves relative to the non-movable part. A connector coupled between the movable part and the object positions the object adjacent the remote center of rotation and rotates it about the remote center of rotation responsive to movement of the movable part. Movement of the connector responds movement of the movable part. First and second force transmitting components coupled to the movable part move the movable part and the connector in first and second directions, respectively. Movement of the connector in the first direction rotates the object about a first axis passing through the remote center of rotation. Movement of the connector in the second direction rotates the object about a second axis passing through the remote center of rotation.

An optical system is provided for creating a mosaic image of a large field of view through a microscope at fast refresh rates of about 25 Hz with a high resolution that is free of blurring or aberrations. The optical system includes an objective lens assembly (), an iris (), one or more scanning mirrors () for high-speed scanning, one or more imaging lenses and irises (), and a high-speed imaging device () arranged in that order from an object. The optical system also includes a mechanism for processing and constructing scanned and captured images into a mosaic image.
