Abstract: Various embodiments for eye imaging, screening, diagnosis, and monitoring are provided. Some embodiments comprise systems for retinal imaging capable of capturing multiple high resolution images using multiple quick succession flashes. The images can be combined to provide for a complete image of the retina of a target FOV without corneal reflections. In some embodiments, a system for retinal imaging can utilize an optical design pupil layout that allocates a large area for the path of imaging rays on the eye pupil by using a narrow buffer area. In other embodiments, a system for retinal imaging can comprise a main device, including an imaging and sensing device, and a robotic system, including an eye tracker and/or sensors, wherein the robotic system is capable of automatically aligning the main device and selecting an optimal imaging mode by detecting a pupil size of an eye and is combined with an AI analysis tool.

Abstract: The present invention features a fiber optic imaging system for generating a customized spectral response comprising (a) an optional optical source for generating optical energy, (b) an optical system for focusing multi spectral optical energy to form a focal surface; (b) a fiber optic element for conveying the optical energy, wherein the fiber optic element has an input end optically coupled to the focal surface to receive the optical energy and an output end to transmit the conveyed optical energy; and (c) a spectral filter optically coupled to at least one of the input and output ends of the fiber optic element, wherein the spectral filter has a filter passband configured to provide the fiber optic element with a pre-determined wavelength transmittance capacity, such that only pre-determined wavelengths of the optical energy are transmitted through the output end, thus achieving a customized spectral response.

Abstract: A sensor system includes a sensor, and an optical train adjustable to provide an optical beam to the sensor from a selected line of sight that may be varied. The optical train includes a wavefront error-introducing element in the optical train, which introduces a wavefront error that is a function of the selected line of sight. There is further a rigid-body wavefront error-correcting element in the optical train. The rigid-body wavefront error-correcting element has a spatially dependent correction structure with the nature of the correction being a function of the selected line of sight. The adjustment of the optical train to the selected line of sight moves the optical beam to the appropriate location of the rigid-body wavefront error-correcting element to correct for the corresponding introduced wavefront error of the wavefront error-introducing element at that selected line of sight.

Abstract: A programmable optical system that dynamically corrects or induces aberrations into the optical path of a missile seeker. The system is dynamic in that the amount and type of aberration may be changed while the missile is in flight. The dynamic correction is accomplished by means of deformations applied to a low-mass mirror or mirrors in the optical path of the missile seeker. The missile includes an aspheric dome, and the optical system is dynamically compensated for aberrations introduced by the dome as the seeker system is moved through the field of regard.

Abstract: An optical system includes a window made of a curved piece of a transparent material having an inner surface and an outer surface. The inner surface has a nominal inner surface shape defined by a first conicoidal relationship, and the outer surface has a nominal general aspheric surface shape. The optical system also typically includes a sensor and an optical train on the side of the inner surface of the window. The accuracy of the shape of the inner surface is tested by directing a coherent light beam through a remote focus of the inner surface, reflecting the light beam from the inner surface toward an adjacent focus of the inner surface, reflecting the light beam from a spherical reflector at the adjacent focus of the inner surface and back toward the inner surface, reflecting the light beam from the inner surface back toward the remote focus, and interferometrically comparing the reflected beam arriving at the remote focus with a reference beam.
