摘要： An optical system includes an active focus element that maintains an image in focus over a range of object distances. The active focus element and aperture stop are positioned such that the image scale and the image spatial resolution are also invariant (or at least have a reduced sensitivity) with respect to object distance.

摘要： A free-space optical data transmission system, comprised of first and second transceivers spaced a substantial distance from each other and having telescopes aimed at each other. Each transceiver has a light transmitter for transmitting data-encoded light from its telescope to the other telescope, and a light receiver for receiving the data-encoded light from the other telescope. Each transceiver has a wavefront sensor for determining the curvature of the wavefront of light transmitted between the telescopes, which light wavefront may be distorted by atmospheric aberrations, a deformable curvature mirror operably connected to the wavefront sensor and positioned in the path of the data-encoded light for modifying the wavefront curvature of the data-encoded light in response to the wavefront curvature determined by the wavefront sensor. Preferably, each transceiver has an arrangement for distinguishing/separating the transmitted and received light waves for bi-directional data transmission.

摘要： An apparatus for measuring optical aberrations of the human eye wherein the person positions his or her eye on an optical axis of the apparatus and looks at an illuminated target on the optical axis that is visible to the eye for allowing the eye to focus on the target and establish a position of the eye. A collimating lens on the optical axis is movable along the optical axis for adjusting the apparent optical distance between the eye and the target. A light source directs a predetermined light beam along the optical axis into the eye and onto the retina of the eye as a spot of light. A lens reimages the light scattered from the light spot on the eye retina into a wavefront curvature sensor that forms two oppositely defocused images on an image detector, and a computer processes and analyzes the two defocused images for measuring the optical aberrations of the eye.

摘要： A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. Eye reflections from the subjects' eyes are used to steer a high resolution camera to the eyes in order to capture images of the irises. A circular deformable minor driven by one or more annular forces can be used to focus the camera. A circular mirror substrate is mounted by its circumference onto a minor mount and driven by an annular drive element that contacts the minor substrate along a ring. If the annular drive element has a certain diameter relative to the circumference of the mirror substrate, the mirror substrate will be deformed in the shape of a sphere.

摘要： The present invention provides a rapid, high quality iris imaging system. In one embodiment, on-axis illumination is used. A single steering mechanism steers both the camera and the illumination, without parallax issues. The illumination beam can be combined along the camera's optical axis before or after the fine steering and focus correction mechanism. In a pre-correction configuration, the iris illumination spot can be reduced in size to be only slightly larger than the iris. In both the pre and post-correction configuration, the eye safety limits will be most critical at the subject, which allows for maximization of the illumination flux.

摘要： An iris imaging system used for biometric identification provides a combined iris imager and wavefront sensor. The detector array allows for independent readout of different regions, such that a wavefront sensor region can be read out fast while allowing signal to integrate on the iris imaging region. Alternatively, the entire array may be used for wavefront sensing during an acquisition phase, and then at least a portion of the array may be switched to be used for iris imaging during a subsequent imaging phase. An optical periscope optionally allows various optics to be inserted in front of the combined iris imager and wavefront sensor. In another embodiment, the glint image of an on-axis or near on-axis illumination source is picked off at the image plane and directed to the wavefront sensor optics, while allowing all of the light from the iris field to pass through to the iris imaging camera.

摘要： A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. Light illuminates the subjects' eyes and a high resolution camera captures images of the irises. The images of the irises are processed by a post processing module to improve their quality. In one approach, the point spread function of the image capture subsystem is estimated using glint reflections from the eye, and the estimated point spread function is used in deconvolution to increase the resolution of the iris images. The post processed iris images have sufficient resolution to be used for biometric identification.
