Definitions

  • the invention relates to an imaging device having two display panels, and optical elements for transmitting the image produced on the display panels into both eyes.
  • Several head worn imaging devices are known in the art.
  • the majority of said devices comprises two miniature display panels, one for each eye; the display panels are arranged in front of the eyes - which entails a disadvantageously protruding construction -, or on both sides; in the latter case the image is reflected into the eyes by mirrors placed in front of the pupils.
  • the two mirrors are the elements limiting the possibility to reduce the size of the device; therefore it is expedient to place the display panels between the mirrors.
  • Lens systems consisting of magnifying lenses are used to focus the beams of light starting from the screens into the eyes. Since unfocused, discoloured, deformed images cannot be allowed when displaying video pictures, the focusing optical elements must comply with high requirements .
  • 06331927A also shows a device having a lens system consisting of two convex lens members, where one of said lenses is arranged between the eye and a mirror, and the other one between the mirror and an LCD, directly on the surface of the LCD.
  • the focusing element is a single convex lens arranged between the eye and a mirror.
  • a common drawback of the above mentioned devices is that the image is produced by means of simple magnifying lenses, and the distortions of the image produced by the lenses are not corrected at all.
  • a lens system consisting of two converging lens members is not better because the second lens member only continues to magnify the image focused by the first lens member, thereby increasing the defects of the image. The result is that the image is unfocused, deformed, deflected, and the edges are discoluored.
  • Another common drawback of the above mentioned known solutions is that only a single light source placed in the middle of the device is used to illuminate both LCDs.
  • a further common feature of the described prior devices is a bulky outer cover enclosing the front part of the head in order to enable the user to wear the device in the manner as a pair of glasses can be worn. It is disadvantageous, however, that the cover occupies the ridge of the nose and the ears; consequently, spectacled persons cannot wear the device together their own glasses or, at least, wearing the imaging device is very unconfortable.
  • Another object of the invention is to make the device suitable for being fixed to a pair of glasses; in this case, spectacled persons can wear the device mounted on their own glasses, and non-spectacled persons can fix the device on the head by means of a spectacle frame having lenses of 0 dioptre.
  • the invention is based on the recognition that a lens system consisting of at least three members should be used in order to eliminate the defects in the image or to reduce them to a minimum; at least two members of the lens system should combine converging and diverging lenses, i.e. form a corrected system of converging and diverging lenses correcting the chromatic aberration on the wave length of at least two primary colours.
  • flat display panels should be used, each emitting light or being transilluminated separately.
  • the volume of the device can be reduced to a minimum if the light paths between the displays and the pre-eye mirrors are deflected on both sides by means of a first mirror placed parallel to the corresponding pre- eye mirror.
  • the simplest means to fix the device to a pair of glasses is a clip adapter made of a flexible sheet strip, and having clips on the ends and an upright tongue in the middle.
  • the opposite of the tongue can be a nest formed by e.g. a bracket with two hook-like ribs on the side facing the user's face.
  • the operating circuits of the display panels should be placed separately from the device (e.g. clipped to the clothes or put in the pocket) , but connected to it by means of an aerial cable.
  • the object of this invention is accomplished by an imaging device having two screens and an optical system consisting of pre-eye mirrors and lenses for transmitting beams of light from the screens to the eyes.
  • the device is characterized in that a lens system consisting of at least three members is arranged in each light path starting from the screens and reflected by the pre-eye mirrors into the pupils of the eyes; two members of the lens system, a converging lens and a diverging lens, are placed side by side directly or with a distance between them, said members forming together a corrected subsystem; and the third member of the lens system is placed separately from said subsystem and comprises a converging lens, occasionally combined with a diverging lens.
  • the lens members are arranged partly between the pre-eye mirror and the pupil, partly between the pre-eye mirror and the screen in order to focus the beam of light in several steps; therefore each lens or each group' of lenses refracts the rays of light passing through the periphery of the lens by a smaller angle, advantageously reducing the defects in the image.
  • the resulting focal length of the lens system corresponds to the distance between the screen and the image-side main plane of the single magnifying lens being theoretically equivalent to the lens system, so that an infinitely distant image can be viewed without accommodation.
  • the lens between the pre-eye mirror and the pupil is placed close to the mirror to have a solid device which can be mounted compactly on the glasses.
  • each display is an illuminator emitting light, e.g. a display of active matrix electroluminescent (AMEL) type, or a transparent, e.g. LCD display transilluminated by a separate light source placed close to the display.
  • AML active matrix electroluminescent
  • the subsystems consisting of the converging and diverging lenses are arranged between the screens and the pre-eye mirrors; and the converging lenses forming the third member of the lens system are arranged between the pre-eye mirrors and the pupils.
  • the two-member subsystems arranged between the screens and the pre-eye mirrors consist - along the path of the light - of convex converging lenses of a smaller refractive index and meniscus-shaped diverging lenses of a bigger refractive index; the converging lenses forming the third member between the pre-eye mirrors and the pupils are planoconvex or meniscus-shaped converging lenses, the non-convex sides of which face the pupils.
  • the angle of incidence ⁇ of the outside rays of light arriving from the screen i.e. the angle between the incident ray and the normal at the point of incidence
  • the angle of departure ⁇ j_ of the same ray i.e. the angle between the emerging ray and the normal at the point of emergence
  • the converging lenses forming the third members are placed between the screens and the pre-eye mirrors; and the two-member subsystems consisting of converging and diverging lenses are arranged between the pre-eye mirrors and the pupils.
  • the two-member subsystem comprises two lens cemented together: a convex converging lens of smaller refractive index, made of e.g. crown glass, and a meniscus-shaped diverging lens of bigger refractive index, made of e.g. flint glass; and the outer form of the lens system is convex.
  • the lens system corrects the aperture defect (spherical aberration) , and reduces the field-deflection and the astigmatism. If the lens members - dependent on the kind of glass - have different dispersive power (Abbe number) , and the focal points for two colours (e.g. blue and red) coincide, the lens system can be considered as free from chromatic aberration (achromatic lens system) .
  • each display panel is transilluminated by a flat illuminator, or each display panel itself is an illuminator.
  • the lens system can be constructed similarly as in the previous embodiment.
  • the lens system comprises two-member subsystems consisting of converging and diverging lenses; said subsystems are arranged both between the screens and the pre-eye mirrors and between the pre-eye mirrors and the pupils; thereby the aberrations can be further reduced.
  • the two- member subsystems arranged between the screens and the pre-eye mirrors consist - along the path or the light - of convex converging lenses of a smaller refractive index and biconcave diverging lenses of a bigger refractive index;
  • the two- member subsystems between the pre-eye mirrors and the pupils consist of meniscus-shaped diverging lenses of a bigger refractive index and meniscus- shaped converging lenses of a smaller refractive index, where the outer concave sides of the lenses of the subsystems face the pupils.
  • Such a lens system reduces or even entirely corrects the astigmatism and the field-deflection (anastigmatic lens system) , and reduces the spherical aberration, too.
  • the two- member subsystem arranged between the screen and the pre-eye mirror is a cemented achromatic pair of lenses consisting - along the path of the light - of a meniscus-shaped diverging lens of flint glass and a meniscus-shaped converging lens of crown glass; the lens system between the pre- eye mirror and the pupil is symmetrical to the other lens system between the screen and the pre- eye mirror.
  • the whole lens system corrects the distortions at the edges of the image, reduces the defects in the colour- magnification causing blurred and discoloured edges, and reduces the spherical aberration and the sphero-chromatic aberration (i.e. the spherical aberration depending on the colour of the light, too) .
  • the display panels with the screens are arranged either in the area between the pre-eye mirrors, parallel to each other, but back to back, or outside the area between the pre-eye mirrors, at the boundary of said area, side by side in the same plane, (with the screens) facing the same direction.
  • the display panels either emit light or are transilluminated by means of a flat illuminator placed close behind the panels. If the display panels are arranged outside the area between the pre-eye mirrors, at the boundary of said area, a further so called first mirror is arranged in the light path on both sides of the device; the first mirror is parallel to the corresponding pre-eye mirror and reflects the rays of light coming from the screen toward the pre-eye mirror.
  • the left side display panel and the optional illuminator, the left side pre-eye mirror and the left side lenses are held together by a left side housing; similarly, the right side display panel and the optional illuminator, the right side pre-eye mirror and the right side lenses are held together by a right side housing.
  • Said housings are fixed to a common framework, and at least one of said housings can be slided relative to the framework along guideways parallel to the line connecting the centres of the screens, so that the pre-eye mirrors can be set in front of the pupils.
  • the invention also relates to an imaging device having two screens and an optical system consisting of pre-eye mirrors and lenses for transmitting beams of light from the screens to the eyes.
  • This device is characterized in that the two screens are arranged side by side, in the same plane, facing the same direction; in front of each screen, a first mirror is arranged defining an angle of 45° ⁇ 10° relative to the plane of the screens, and an angle of 90° ⁇ 20° relative to the other first mirror; accordingly, the first mirrors form a V-shape, the open side of which is turned away from the screens; the first mirrors project the light beams from the screens onto the pre-eye mirrors arranged parallel to the first mirrors; and the pre-eye mirrors reflect said light beams further into the eyes of the viewer.
