Definitions
- the invention relates to a binocular designed to project an object plane to infinity, an object plane which may be that of a micromonitor or an LCD micro-screen, with the aim, for an operator, for example of viewing the image. of a scene at the same time in the visible spectrum and in the infrared spectrum using a thermal camera, but also to be able to visualize by superimposition the image of a scene and a completely different image, 0 for example a symbolic image.
- binoculars are used on observation binoculars, riflescopes, helmet sights, fire control sights, TV sight for airplane pilots and even, in the purely civil field, on headsets for video games 5 as well than on image walkmans and, more generally, for any system of restitution and / or inlay of images by headphones with superposition, or not, of direct images.
- a binocular with two optical systems respectively for 0 the two eyes, is distinguished from a biocular system, such as for example a magnifying glass, which has only one optic for the two eyes.
- Binoculars with two identical optics are known which are centered on the two axes of the two eyes, but they require two identical objects, which doubles the price.
- Binoculars with two optics and recombination of the beams by prisms or mirrors are also known, with or without adjustment of eye gap, with therefore a single object, but these systems are still too complex.
- the present invention aims to provide a simple, light, compact, achromatic and low-cost binocular.
- the invention firstly relates to a binocular system for projecting an object plane at a predetermined distance, characterized by the fact that it comprises two identical aspherical mirrors inclined and mounted symmetrically with respect to a plane.
- the system of the invention is simple and light since it only has one diopter per eye.
- the system can comprise two angle references associated respectively with the two mirrors, which is preferable when the object plane is defined by a micromonitor, much more cumbersome than an LCD micro-screen.
- the applicant also here proposes a set of a portable data processing terminal and a binocular system of the invention, including the object plane is defined by a screen connected to the terminal for entering image data received by the terminal.
- a portable terminal it is possible to envisage a portable personal computer or a cellular radiotelephony terminal, for, for example, better use in real time of road navigation data or, even, for the sake of confidentiality, of information to be viewed but to be hidden from view by third parties.
- FIG. 1 is a schematic top view in section of the preferred embodiment of the latter, connected to a GSM handset, and
- FIG. 1 is a perspective view illustrating the variant.
- the binocular system represented in FIG. 1 makes it possible to project at a predetermined distance an object plane in which a screen 1 has been placed, in this example an LCD liquid crystal screen, making it possible to display for example the image of a scene. captured by an associated camera and / or possibly embed symbols and other information.
- Two identical, aspherical mirrors 5 are inclined and mounted symmetrically with respect to the axis of FIG. 1 representing a median plane 10 of symmetry of the system, the display screen 1 being centered on the plane 10 perpendicular thereto .
- mirrors 5 then semi-transparent, possibly dichroic, to superimpose the real image of the captured scene, illustrated by the beams 7, and an IR image of the camera.
- the cutting plane said to be horizontal for the convenience of the presentation, crosses the screen 1 and the mirrors 5 substantially at mid-height thereof. It is obviously understood that the choice here of a horizontal section plane and a median plane 10 of vertical symmetry has the sole purpose of simplifying the presentation and that the system of the invention retains its properties whatever its orientation .
- References 2 designate the eyes of an observer wearing a helmet on which the system is mounted. It could for example be a helicopter pilot whose helmet would carry, integral with the binocular system, an infrared camera replacing the GSM handset 9 and controlling the screen 1 to form a head-up viewfinder.
- FIG. 1 there are shown any three points or pixels of the object plane of the screen 1, from which three respective pairs of beams of divergent rays 3 depart, each beam of each pair reaching a particular mirror 5 and being reflected therein in the form of a beam of rays here parallel 4.
- the three beams 4 of each mirror 5 intersect at the level of the associated eye 2.
- the observer can scan the screen 1, in the horizontal plane of the figure, constantly having a clear image, here at infinity, of the screen 1.
- Each of the three positions of the beams 3, 4 of each mirror 5 illustrates a particular position of such a visual exploration of the observable field.
- the shape of the mirrors 5, of the kind of a spherical surface of revolution used off-axis, is such that a vertical scan of the screen 1, therefore leaving the plane of FIG. 1, likewise retains the optical properties above, from object image to infinity.
- a single optical element (5), off-axis, monobloc alone fulfills the desired function of returning the object plane to a predetermined distance located within the accommodation range of the human eye. , i.e. about 25 cm to infinity.
- FIG. 1 have been sketched, in dashed lines, two mirrors 6 for 90 ° deflection of the two sets of beams 4, in order to explain the variant of FIG. 2.
- the mirrors 5 in FIG. 1 have tilted substantially 90 ° downwards around a fictitious axis extending in the plane of FIG. 1 and passing through the two deflection mirrors 6 and the image screen. partner has pivoted around the same axis to occupy a high position, which could be well above that shown.
- the homologous elements of FIG. 1 have kept their references.
- a configuration of this type makes it possible to replace the LCD screen 1, mounted at eye level 2, with a micromonitor 11, more efficient but too bulky.
- the screen of the monitor 11, occupying a high position, is therefore turned downwards, and here horizontal.
- the descending beams 3 which it emits are therefore substantially vertical and are reflected, in the form of two sets of ascending beams 41 with parallel rays, by the two respective aspherical mirrors 5 facing upwards.
- the two sets of beams 41 are reflected on the two respective deflection mirrors 6, here planes, to form the two sets of beams 4 of the so-called horizontal plane.
- the return mirrors 6 are preferably placed at a maximum distance from the aspherical mirrors 5, that is to say that they can then be of size reduced while covering the desired angular opening (angular size of the screen) since the image plane (eyes 2) is then close to the reflecting mirrors 6.
- the return mirrors 6 are arranged on the paths of the beams 3, that is to say that the aspherical mirrors 5 retain the position of FIG. 1 and that only the screen 1 ( or a monitor 11) has tilted approximately 90 °.
- the object plane is not projected to infinity, but simply at a finite distance, included in the range of accommodation of the eyes 2, c ' that is to say, from 25 centimeters to infinity.
- the mirrors 5, and / or where appropriate the deflection mirrors 6, have the desired shape so that each beam 4 of any kind is no longer with parallel rays but on the contrary with diverging rays coming from the object plane projected at a finite distance .
- the object plane of the screen 1, 11 is projected at an increased distance from the eyes 2 so that the observer can see it clearly.
- the binocular system of the invention can be used for the visualization of any type of information such as for example synthetic images or symbols or characters representing data.
- an assembly may be provided consisting of a portable data processing terminal and the binocular system according to the invention, the screen of which, arranged at the level of the object plane, is connected to the terminal for entering image data received or generated by the terminal.
- It can for example be the cellular radiotelephone terminal 9 or even a portable personal computer.
