A laser energy window arrangement especially usable in a tactical aircraft having night vision equipment-aided cockpit visual information input requirements. The laser energy window arrangement enables use of laser apparatus directed external to the aircraft for target designation or other purposes while minimizing the amount of energy from such laser returning spuriously inside the cockpit where it inherently acts a noise signal for night vision equipment. The laser energy window limits the portion of the aircraft windshield or canopy exposed to laser radiation and its effects to a relatively small area, an obscurable area generating significantly reduced amounts of spurious return energy in comparison with use of the laser directly through an unlimited windshield, canopy, or other type of transparency. Transmission of spurious return energy from the laser energy window to remaining portions of the windshield or canopy is precluded by interruption of transmission paths within the windshield or canopy material and transducing the interrupted path energy into heat dissipated within or outside of the aircraft and not affecting the remainder of the canopy. Potentially increased aircraft to target standoff range, reduce need for aircrew use of laser eye protection gear, reduced laser induced windshield or canopy degradation and other benefits are identified for aircraft uses of the invention.

A self-contained, military usage compatible, stabilized illumination calibration system and method of using same to enable in-the-field accurate determination of the low-level light falling on the surface of a night vision apparatus resolution chart and attending adjustment of a night vision device. Use of such charts, such as the chart of U. S. Pat. No. 4,607,923, preferably includes known levels of illumination at several different expected night vision goggle compatible lower-levels in order to both evaluate and adjust the performance of a night vision device prior to its use or during extended use periods. The disclosed system is digital computer controlled and provides an accurate, easy to use, and low cost alternative to previous laboratory-like methods of determining night vision evaluation illumination. The disclosed system provides go or no go indications of achieved chart illumination.

A cost considered arrangement for evaluating local illumination interference with operation of a night vision apparatus in for example the confines of an illumination inclusive aircraft cockpit. The evaluation is especially applicable to identifying interference between aircraft instrument lighting having infrared content for example, and night vision apparatus operation in the aircraft. The evaluation is cost is limited by use of a common household lamp night vision apparatus source calibrated with a common light measuring instrument operated at close range and with modification of the measured illumination through mathematical manipulation of the source operating distance to achieve the low light levels needed for night vision apparatus operation. A standard visual acuity chart and multiple operator interpretations of the chart resolutions achieved are included.

A quad-emissive display apparatus to provide suitable emissive energy in four spectral bands to provide simultaneous evaluation of sensors having different spectral sensitivities. The apparatus can simultaneously provide four spectral bands of visible (0. 4 to 0. 7 microns), near infrared (0. 7 to 1. 0 microns), short wave infrared (1. 0 to 3. 0 microns) and the long wave infrared (8. 0 to 14. 0 microns) radiation.

A method, apparatus and program product are presented for determining an orientation of a Landold C in an image containing a plurality of pixels. A center of the Landolt C is determined. A plurality of rays is extended from the center of the Landolt C radially outward. A plurality of distances is determined, where each distance of the plurality of distances represents a distance from the center of the Landolt C to a darkest pixel along each ray of the plurality of rays. A peak in the plurality of distances is identified. And the orientation of the Landolt C is determined based on the peak in the plurality of distances.

A method, apparatus and program product are presented for detecting an image. Ring contour images are created by blurring the image, posterizing the blurred image at a plurality of levels and creating the ring contour images from each of the posterized images. Convex hull images are created by creating a plurality of corner images from corners within the image located by at least two different corner algorithms, finding a bounding rectangle that encompasses the ring contour images, cropping the corner images using the bounding rectangle, applying a threshold to the cropped corner images, and creating the convex hull images by generating a convex hull from the corners in each of the cropped corner images. A plurality of triangles is created by fitting a triangle with an orientation to the ring contour images and the convex hull images. Finally the orientation of the triangle is determined from the plurality of triangles.

A novel optical device and method for measuring intraocular light scatter in a human vision system of a subject is described which comprises first and second light sources of respective predetermined intensities, the images of which are optically folded along a common optical axis and projected into the vision system of the subject, the first source being of intensity sufficient to generate intraocular haze in the vision system of the subject, the second source being movable in a plane substantially perpendicular to the axis along which its image is projected whereby the second source image as viewed by the subject may be selectively viewed with respect to the first source image to measure the apparent peripheral extent of the haze surrounding the first source image.
