An etched plate used to simulate an infrared target for trainees using siated weapons. Selectively etching the plate in a variety of fashions successfully imitates the thermal signature of the simulated target. The simulated weapons are then 'fired' at the plate and hits recorded. The plate may be electrically heated.

Thermal target and weapon fire simulator for thermal sights

A pilot training simulator system is disclosed that simulates a predetermd vehicle and the operational environment pertinent to the vehicle in such manner that the pilot being trained in the system may be responsive to the realistic impressions effected by this combination. Included in the system is a first subsystem for producing a video readout of various terrain and target scenes, a simulated vehicle cockpit second subsystem to which the terrain and target scenes are provided, and a third subsystem for providing a motion picture to the windshield of the simulated vehicle cockpit. A motion generator imparts realistic movements to the first subsystem and simulated vehicle cockpit, and console controls permit the manual operational control of both.

Pilot training simulator

A retroreflector evaluation system is disclosed as incorporating a laser and a plurality of laser light processing optical elements associated therewith in such manner as will permit the making of reflectance measurements at any or all points on the surface of retroreflective or other reflective samples or devices, thereby providing an indication of the intensity, uniformity, and other reflectance characteristics which determine the quality thereof.

Retroreflectance measurement system

An automatic adjustable radiant energy filter system adapted for protecting uman eyes (and other optical devices) from dangerous intensities of laser light or other types of radiation during experimentation therewith is disclosed as including a pair of relatively moving polarized filters, one of which is automatically positioned with respect to the other as a consequence of a unique photodetector and negative feedback system combination sensing and controlling the aforesaid laser light radiation that passes therethrough in accordance with a predetermined intensity level. Fixed filters may be selectively mounted in front of said polarized filters, in order to control the amount and frequency of ambient radiant energy supplied thereto; and a shutter and unique control subsystem therefor are combined with the aforesaid photodetector in such manner as to completely stop said laser light radiation from being supplied thereto whenever the intensity thereof exceeds a given dangerous level, thereby completely protecting the aforesaid human eyes therefrom, too.

Laser safety goggles

A landing signal officer trainer having a cylindrically rolled holographic ilm with stored attitude data of yaw and pitch rotatably and slidably mounted in conjunction and relation to a laser beam source to vary yaw and pitch image attitude of a plane, a pechan prism rotatable to vary roll of the plane image, a zoom lens system to vary range of the plane image, enlarging lens apparatus to present an adequate image to a landing signal officer (LSO) observing the image, and a control panel operable by an instructor to vary the plane attitude and range position in accordance to the signals given by the trainee and thus provide unprogrammed training in guiding landing aircraft without use of actual equipment and in a manner in which the trainee participates. The invention further contemplates the provision of a ship holographic image variable in pitch and control apparatus for selectively coordinating plane range and ship pitch to produce land or abort conditions.

Aircraft landing signal officer trainer

A simulator including an improved holographic heads up display system in ch the projection of images, via a plurality of slide projectors, through several light ray channels or paths, are controlled by polarizer light valves, associated one with each respective channel, and the output or outputs of the channels dependent upon the on-off conditions of the several light valves, is passed through a holographic lens as a window to the eye of an observer. Apparatus is also provided to maintain a desired light level intensity at said window by coordinated adjustment of the light valves. A further aspect of the invention contemplates the provision of vehicular control mechanism connected to recording charts on which a prerecording of correct response to a programmed display has been made on each chart to compare the actual trainee controls movement with the proper movement for the exercise.

Simulator including improved holographic heads up display system

A weapons training simulator in which a multilayer composite movie film fed of a normal film for projecting a non-polarized image of target and background and a polarized film for projecting a polarized target image is utilized in a projector to project the polarized and non-polarized images on a non-depolarizing screen and in which a weapons mounted polarized light sensor circuit is provided to indicate target hit or miss as the weapon is aimed and fired. The invention also contemplates intentional non-registration of the normal and polarized films by a number of frames selected to represent the correct target lead to properly hit the moving target.
