TL;DR: In this paper, a system including binoculars augmented with a computer-generated virtual display of navigation information (hereinafter referred to as “nav glasses”) and marine navigation systems employing such binsoculars is presented.
Abstract: A system including binoculars augmented with a computer-generated virtual display of navigation information (hereinafter referred to as “nav glasses”) and marine navigation systems employing such binoculars. The computer-generated display is superimposed on the real world image available to the user. Nav glasses also have the components needed to link them to a navigation system computer which is utilized to generate the see-through display of the navigation information. They are preferably equipped with sensors compass and an inclinometer for acquiring azimuth and inclination information needed by the navigation computer and a sensor for measuring any magnification of the field of view. The nav glasses can be employed to lock onto a moving target, which can then be tracked by onboard radar. The navigation system in which the nav glasses are incorporated also accept inputs from other sources such as a shipboard compass, a GPS, and other navigation aids; and a route planning system. The field of view of the nav glasses is calculated from information obtained from the nav glasses and navigation sensors, and a display manager generates a pre-fetch display of navigation information from the route planning and radar inputs. This pre-fetch display or image extends well beyond the nav glass field of view. Consequently, as the glasses are shifted from side-to-side or up or down, all that may be required to match the virtual display to the real world image is to align a different segment of the pre-fetch image with the actual field of view. Once the alignment of the virtual display of navigation information and the actual field of view is completed, the virtual overlay is transmitted in coded form to a video output component of the navigation computer and forwarded to the nav glasses where the virtual display is constructed and superimposed on the real world view.

TL;DR: In this article, a large aided static field of view (S/D) ratio of above 2.8 was proposed to reduce the sensation of tunnel vision which normally occurs when binoculars are used.
Abstract: Binoculars designed to provide a large aided static field of view are provided. The binoculars are characterized by S/D ratios of above 2.8, where S is the binoculars' aided static field of view calculated by multiplying the binoculars' magnifying power by the binoculars' semi field of view in object space and D is given by tan-1[(REX + 1.5)/13], where REX is the radius of binoculars' exit pupil and where REX and the constants 1.5 and 13 are measured in millimeters. As a result of the increased S/D ratio, the binoculars of the invention minimize the sensation of tunnel vision which normally occurs when binoculars are used and reduce the user's apprehension of missing activities in his or her peripheral vision. In certain embodiments, a movable field lens unit (F9, F10 - Figures 2-3; F8, F9, F10, F11 - Figure 4) is employed to provide variable power and a negative corrector lens unit (C6, C7, C8 - Figures 1-3; C6, C7 - Figure 4) is employed for aberration correction and to minimize the size of the binoculars. The binoculars are suitable for mass production and general consumer use.

TL;DR: An image stabilized optical system as discussed by the authors is composed of an objective, an eyepiece, and an erecting prism located between the objective and the eyepope, and the two axes of rotation of the gimbals are included in a plane perpendicular to the main optical axes of the telescopic optical systems.
Abstract: An image stabilized optical system in which a pair of telescopic optical systems are arranged in parallel with each other to constitute binoculars. The telescopic optical system is composed of an objective, an eyepiece and an erecting prism located between the objective and the eyepiece. The erect prism is capable of having its incident light optical axis and its emanating light optical axis aligned with each other. The objectives and the eyepieces of the pair of telescopic optical systems are fixed to a casing of the image stabilized optical system, and the erect prisms are mounted on gimbals having two axes of rotation intersecting at right angle with each other. The two axes of rotation of the gimbals are included in a plane perpendicular to the main optical axes of the telescopic optical systems. The plane passes through a middle point of the distance from the objective to the eyepiece.

16 May 2007TL;DR: In this article, the authors proposed a method to optimize human visual function by correcting and/or optimizing high-order optical aberrations in high performance optical devices, such as binoculars, rifle scopes, telescopes, microscopes, night vision goggles and laser eye protection devices.
Abstract: The present invention relates to the optimization of human visual function by correcting and/or optimizing high-order optical aberrations in high performance optical devices. The optimization is particularly useful for high performance devices used under low light conditions such as binoculars, rifle scopes, telescopes, microscopes, night vision goggles and laser eye protection devices.
