Optisk system. Optical system.
Foreliggende oppfinnelse angår optiske systemer som er beregnet brukt sammen med en konsentrert lyskilde som f. eks. kan være en elektrisk lysbuelampe, for å The present invention relates to optical systems which are intended to be used together with a concentrated light source such as e.g. can be an electric arc lamp, to
gi jevn belysning over et begrenset område som er betydelig større en lyskilden, f. eks. provide uniform illumination over a limited area that is significantly larger than the light source, e.g.
det område som begrenses av filmporten i en kinofremviser. the area limited by the film gate in a cinema projector.
For dette formål er det kjent å anvende For this purpose it is known to use
en elektrisk utladningslampe i kombinasjon med et ellipsoidespeil, der lysbuebanen for utladningslampen ligger i speilets brennpunkt og der utladningslampen er slik anordnet at lysbuebanen faller sammen med ellipsoidens hovedakse. an electric discharge lamp in combination with an ellipsoidal mirror, where the arc path for the discharge lamp lies at the focal point of the mirror and where the discharge lamp is arranged so that the arc path coincides with the main axis of the ellipsoid.
For å samle så mye lys som mulig fra kilden er speilet slik anbrakt at dets kant stikker forbi et plan som står normalt på systemets optiske akse og går gjennom brennpunktet. Da lyskilden ikke er en punktkilde vil de stråler som reflekteres fra speilet tilbake mot ellipsoidens konjugerte brennpunkt danne bilder av lyskilden med forskjellig styrke, og disse bilder vil dan- In order to collect as much light as possible from the source, the mirror is positioned so that its edge protrudes past a plane that is normal to the optical axis of the system and passes through the focal point. As the light source is not a point source, the rays that are reflected from the mirror back towards the conjugate focal point of the ellipsoid will form images of the light source with different strengths, and these images will form
nes i et plan normalt på systemets optiske akse og i det konjugerte brennpunkt. Som et resultat av de varierende lysstyrker for de forskjellige bilder på grunn av den forskjellige forstørrelse ved forskjellige punk- nes in a plane normal to the optical axis of the system and in the conjugate focal point. As a result of the varying brightnesses of the different images due to the different magnification at different punc-
ter av speilet vil belysningen over området ikke være ensartet. Videre vil lys som strå- ter of the mirror, the lighting over the area will not be uniform. Furthermore, light such as
ler fra kilden i en større lyskonus ikke bli reflektert mot det konjugerte brennpunkt og de vil gå tapt når det gjelder belysningen i det plan det her er tale om. rays from the source in a larger light cone will not be reflected towards the conjugate focal point and they will be lost when it comes to the illumination in the plane in question here.
Det er imidlertid kjent å overvinne denne vanskelighet i en viss utstrekning ved at det rundt lyskilden på den side som vender fra ellipsoidespeilets fokus, anord-nes en eller to ringformede hjelpespeil omtrent med kuleform, der hvert speil er inn-rettet til å fange opp de stråler som kommer fra lyskilden og som ikke treffes av ellipsoidespeilet, slik at disse stråler kan føres tilbake til brennpunktet. Det annet hjelpespeil er beregnet på å fange opp og reflektere tilbake til lyskilden stråler som ikke fanges opp hverken av det første hjelpespeil eller ellipsoidespeilet, og det an- However, it is known to overcome this difficulty to a certain extent by arranging around the light source on the side facing away from the focus of the ellipsoidal mirror, one or two ring-shaped auxiliary mirrors approximately spherical in shape, where each mirror is aligned to capture the rays that come from the light source and that are not hit by the ellipsoidal mirror, so that these rays can be returned to the focal point. The second auxiliary mirror is designed to capture and reflect back to the light source rays that are not captured by either the first auxiliary mirror or the ellipsoid mirror, and the
net hjelpespeil står lenger fra lyskilden enn det første hjelpespeil og har derfor en tilsvarende større krumningsradius. net auxiliary mirror stands further from the light source than the first auxiliary mirror and therefore has a correspondingly larger radius of curvature.
For å komme frem til et optisk system med en høy optisk virkningsgrad, særlig et system som nærmer seg 100 % lysutnyttel- In order to arrive at an optical system with a high optical efficiency, in particular a system that approaches 100% light utilization-
se, har man måttet utføre de to hjelpespeil, særlig det som står lengst fra kilden, med en nødvendigvis stor diameter og en stor åpning. Reduksjon av den totale størrelse på det kjente system ved en reduksjon av diameteren på ellipsoidespeilet og/eller av de to hjelpespeil kan bare oppnås i de kjente systemer ved en betydelig reduksjon i den lysmengde som fanges opp av hjelpespeilene og dette fører derfor til en reduksjon i systemets optiske virkningsgrad. see, one has had to make the two auxiliary mirrors, especially the one farthest from the source, with a necessarily large diameter and a large opening. Reduction of the total size of the known system by a reduction of the diameter of the ellipsoid mirror and/or of the two auxiliary mirrors can only be achieved in the known systems by a significant reduction in the amount of light captured by the auxiliary mirrors and this therefore leads to a reduction in the optical efficiency of the system.
Foreliggende oppfinnelse søker derfor The present invention therefore seeks
å komme frem til et optisk projeksjonssy-stem som byr på de fordeler at det har små to taldimens joner og maksimum optisk to arrive at an optical projection system that offers the advantages of having small two-dimensional dimensions and maximum optical
virkningsgrad sammen med lav optisk aberrasjon. efficiency together with low optical aberration.
Oppfinnelsen angår således et optisk system for belysning av åpningen i en pro-jektør, omfattende en elektrisk lysbueutladningslampe som danner en konsentrert lyskilde, i kombinasjon med et ellipsoidespeil hvis optiske akse passerer gjennom lampens utladningsbane, idet kanten av ellipsoidespeilet ligger i et plan som står normalt på den optiske akse, og omfattende et optisk reflekterende hjelpesystem som er beregnet på å samle opp og kaste tilbake til lyskilden de stråler denne sender ut innenfor en vinkelkonus som er begrenset av kanten på ellipsoidespeilet, og den er i det vesentlige kjennetegnet ved at det optisk reflekterende hjelpesystem omfatter minst tre hjelpespeil hvert i form av en kulering med liten vinkelåpning og plasert slik at det hjelpespeil som er nærmest ellipsoidespeilet, og som har en radius større enn radius for kanten av ellipsoidespeilet, ligger med den kant som er nærmest kanten av ellipsoidespeilet slik at den overlapper det plan som kanten av ellipsoidespeilet ligger i og reflekterer de stråler hjelpespeilet oppfanger tilbake til lyskilden, mens på hverandre langs systemets optiske akse, bort fra kanten av ellipsoidespeilet med stadig økende krumningsradier for hjelpespeilene, og med kanten av det hjelpespeil som ligger lengst fra ellipsoidespeilet liggende på den ytre begrensning av den vinkelkonus av lys som reflekteres fra ellipsoidespeilet. The invention thus relates to an optical system for lighting the opening in a projector, comprising an electric arc discharge lamp which forms a concentrated light source, in combination with an ellipsoidal mirror whose optical axis passes through the discharge path of the lamp, the edge of the ellipsoidal mirror lying in a plane that stands normally on the optical axis, and comprising an auxiliary optical reflecting system which is intended to collect and throw back to the light source the rays it emits within an angular cone limited by the edge of the ellipsoidal mirror, and it is essentially characterized in that the optical reflective auxiliary system comprises at least three auxiliary mirrors each in the form of a ball ring with a small angle opening and positioned so that the auxiliary mirror which is closest to the ellipsoidal mirror, and which has a radius greater than the radius of the edge of the ellipsoidal mirror, lies with the edge closest to the edge of the ellipsoidal mirror as follows that it overlaps the plane as the edge of the ellipsoidal mirror lie in and reflect the rays the auxiliary mirror captures back to the light source, while on each other along the optical axis of the system, away from the edge of the ellipsoid mirror with ever-increasing radii of curvature for the auxiliary mirrors, and with the edge of the auxiliary mirror farthest from the ellipsoid mirror lying on the outer limit of the angular cone of light reflected from the ellipsoidal mirror.
Med uttrykket «kulering» menes her den del av en kuleflate som vil ligge mellom to parallelle plan som skjærer kulefla-ten, og denne kulering kan om det er nød-vendig for justeringen være delt i to ved diametralt motstående punkter på omkret-sen. The term "knurling" here means the part of a spherical surface that will lie between two parallel planes that intersect the spherical surface, and this knurling can, if necessary for the adjustment, be divided in two at diametrically opposite points on the circumference.
Den ene kant av hjelpespeilet, som ligger nærmest det konjugerte brennpunkt i ellipsoidespeilet, ender fortrinnsvis på den flate som kan sies å omslutte strålene som reflekteres fra kanten av ellipsoidespeilet. Ved hjelp av dette arrangement vil en størst mulig lysmengde fra kilden, som ellers ville gå tapt, bli samlet og ført tilbake til hjelpespeilenes brennpunkt uten at noen av de stråler som reflekteres fra ellipsoidespeilet avskjermes av hjelpespeilet eller speilene. One edge of the auxiliary mirror, which is closest to the conjugate focal point in the ellipsoidal mirror, preferably ends on the surface which can be said to enclose the rays reflected from the edge of the ellipsoidal mirror. With the help of this arrangement, the largest possible amount of light from the source, which would otherwise be lost, will be collected and brought back to the focal point of the auxiliary mirrors without any of the rays reflected from the ellipsoidal mirror being shielded by the auxiliary mirror or mirrors.
En fordel man oppnår ved dette er at størrelsen på det ferdige optiske system blir langt mindre enn tidligere, mens virk-ningsgraden tilsvarende økes ved at de små halvkuleformede hjelpespeil kan tilpasses individuelt til et hvilket som helst optisk system hvis virkningsgrad lian variere på grunn av individuelle svingninger og for-andringer i lampen eller tilsluttede kompo-nenter. An advantage achieved by this is that the size of the finished optical system is much smaller than before, while the efficiency is correspondingly increased by the fact that the small hemispherical auxiliary mirrors can be adapted individually to any optical system whose efficiency varies due to individual fluctuations and changes in the lamp or connected components.
Videre kan kanteffektene ved de halv-kulespeil eller ellipsoidespeil som anvendes igjen kompenseres ved individuell innstil-ling av de omgivende hjelpespeil, slik at man får utsendt en mest mulig samlet lyskonus fra lyskilden, hvorved denne kan innrettes nøyaktig og utnyttes på best mulig måte. Furthermore, the edge effects of the hemispherical mirrors or ellipsoidal mirrors that are used can again be compensated for by individual adjustment of the surrounding auxiliary mirrors, so that the largest possible overall cone of light is emitted from the light source, whereby this can be precisely aligned and utilized in the best possible way.
For at oppfinnelsen lettere skal kunne forstås vil den i det følgende bli nærmere beskrevet under henvisning til tegningen som viser en halvdel av et snitt, gjennom et optisk system utført i henhold til oppfinnelsen, der snittplanet går gjennom systemets optiske akse. Lyskilden er vist ved 1 og ellipsoidespeilet ved hvis ene brennpunkt lyskilden er anordnet er betegnet med 2. Lyskilden er vist i form av en elektrisk utladningslampe, fortrinnsvis av xenontypen, og lampen er slik plasert at aksen for utladningsbanen mellom elektro-dene i det vesentlige faller sammen med aksen for det optiske system. Dette krever at speilet 2 må være forsynt med en sentral åpning 3 gjennom hvilken en ende av utladningslampen stikker. Lys fra lyskilden mottas av overflaten av speilet 2 og blir rettet mot det konjugerte brennpunkt for speilet 2. Begrensningsstrålen som repre-senterer det lys som reflekteres fra kanten 4 av speilet 2 er betegnet med b. Kanten 4 er avsluttet i et plan c som går gjennom det førstnevnte brennpunkt og står perpendi-kulært på systemets optiske akse. In order for the invention to be easier to understand, it will be described in more detail in the following with reference to the drawing which shows a half of a section, through an optical system made according to the invention, where the section plane passes through the optical axis of the system. The light source is shown at 1 and the ellipsoidal mirror at one focal point of which the light source is arranged is denoted by 2. The light source is shown in the form of an electric discharge lamp, preferably of the xenon type, and the lamp is positioned such that the axis of the discharge path between the electrodes essentially falls along with the axis of the optical system. This requires that the mirror 2 must be provided with a central opening 3 through which one end of the discharge lamp protrudes. Light from the light source is received by the surface of the mirror 2 and is directed towards the conjugate focal point of the mirror 2. The limiting ray representing the light reflected from the edge 4 of the mirror 2 is denoted by b. The edge 4 is terminated in a plane c which goes through the first-mentioned focal point and is perpendicular to the optical axis of the system.
For å avskjære de stråler som sendes ut av lyskilden i en vinkel begrenset av planet c og for å reflektere disse stråler tilbake til ellipsoidespeilets brennpunkt, kan ett eller flere hjelpespeil, for eksempel et speil 5 være anordnet der det ene eller alle hjelpespeil er i form av en kulering med sitt krumningssenter liggende i brennpunktet a. Radius for hjelpespeilet 5 er større enn radius for kanten 4 av ellipsoidespeilet 2. Den kant på hjelpespeilet 5 som ligger nærmest det konjugerte brennpunkt for speilet 2 ender i en flate som ligger langs strå-len b, slik at hjelpespeilet ikke stanser noen av de stråler fra lyskilden som reflekteres direkte av speilet 2. Hjelpespeilet 5 samler således lys innenfor vinkelkonusen a, og dette lys ville ellers gå tapt, men blir nu returnert tilbake til brennpunktet a. In order to intercept the rays emitted by the light source at an angle limited by the plane c and to reflect these rays back to the focal point of the ellipsoidal mirror, one or more auxiliary mirrors, for example a mirror 5, can be arranged where one or all auxiliary mirrors are in the form of a spherical ring with its center of curvature lying at the focal point a. The radius of the auxiliary mirror 5 is greater than the radius of the edge 4 of the ellipsoidal mirror 2. The edge of the auxiliary mirror 5 that is closest to the conjugate focal point of the mirror 2 ends in a surface that lies along the ray b, so that the auxiliary mirror does not stop any of the rays from the light source that are reflected directly by the mirror 2. The auxiliary mirror 5 thus collects light within the angle cone a, and this light would otherwise be lost, but is now returned back to the focal point a.
I stedet for f. eks. å bruke et enkelt hjelpespeil 5 i form av en kulering, skal det i henhold til oppfinnelsen benyttes en kombinasjon av minst tre speil som f. eks. 6,7 etc, for å få et liknende resultat. Den kant av speilet 7 som ligger nærmest ellipsoidespeilet vil da ende i et plan, f. eks. det plan som er antydet ved d, mens resten av speilet 7 ellers ligger i skyggen bak speilet 6. Instead of e.g. to use a single auxiliary mirror 5 in the form of a ball ring, according to the invention a combination of at least three mirrors must be used, e.g. 6,7 etc, to get a similar result. The edge of the mirror 7 which is closest to the ellipsoidal mirror will then end in a plane, e.g. the plane indicated by d, while the rest of the mirror 7 otherwise lies in the shadow behind the mirror 6.
Fordelen ved å bruke tre eller flere speil, The advantage of using three or more mirrors,
6,7 etc, i stedet for det enkle speil 5 er at 6,7 etc, instead of the simple mirror 5 is that
den plass som kreves og den totale diameter på det ferdige optiske system redu-seres vesentlig og dessuten at det optiske the space required and the total diameter of the finished optical system is significantly reduced and furthermore that the optical
system kan anvende små stillbare og for-holdsvis rimelige kuleringformede speil, der system can use small, adjustable and relatively inexpensive bull-ring-shaped mirrors, where
man ellers måtte anvende nøyaktig be-arbeidede og kostbare ellipsoidespeil. one would otherwise have to use precisely machined and expensive ellipsoid mirrors.
Det er klart at ved å bruke mer enn It is clear that by using more than
to hjelpespeil som hvert har en liten åpning, vil den optiske aberrasjon som frem-bringes av hvert hjelpespeil sammen med two auxiliary mirrors that each have a small opening, the optical aberration produced by each auxiliary mirror together with
den samlede optiske aberrasjon som frem-kommer i kombinasjon av slike speil være the total optical aberration that appears in combination of such mirrors be
