Definitions
- Optical carrier and housing arrangement for holding a color splitter system and several image converters
- the invention relates to an optical carrier and housing arrangement for accommodating a color splitter system and a plurality of image converters, in particular CCD receivers, according to the preamble of patent claim 1.
- a multiple array optical module for an encapsulated CCD receiver having a color camera is known from German published patent application DE 197 43 526 AI.
- a beam splitter arrangement in the form of a prism with wavelength-selective mirror layers for separating the incident radiation into at least three spectral detection channels, the CCD receivers being integrally connected to the surfaces of the beam splitter arrangement on the light exit side.
- the applied layer sequence comprises three separate individual filters, each with one
- the resolution can be increased with the same number of pixels in comparison to single-chip cameras provided with color filters.
- Each color separation signal is displayed with a resolution that corresponds to the full resolution of a CCD black and white receiver.
- Another advantage is the improved color fidelity and color resolution compared to single-chip cameras combined with higher light sensitivity, which results in considerable market relevance, especially for the field of medical technology.
- the color division of multiple CCD chip cameras is carried out using a complicated color splitter prism. As shown, the chips are either fixed directly on the color splitter prism or with a small air gap to the prism on the inside Housing walls of the camera attached. In the latter case, particularly complicated adjustment structures are necessary, so that the production costs are considerably higher.
- a three-color splitter system is known from US Pat. No. 5,305,146, where a quite complicated arrangement of color filters and cylindrical lenses is necessary, which leads to problems when miniaturization of the overall arrangement is sought.
- JP-6-180414 A In order to reduce the assembly effort in the production of CCD cameras, it has been proposed according to JP-6-180414 A to start with a housing arrangement which has a prefabricated prism block. CCD chips in a housing are introduced into U-shaped recesses and attached there by adhesive after adjustment. The overall dimensions of the arrangement there are reduced by the depth of the U-shaped recesses, which accommodate the majority of the CCD receivers. According to JP-6-180414 A, it is not possible to integrate parts of the head and / or control electronics.
- JP-5-14910 A shows a direct mechanical connection between the CCD chips and the radiation output-side surfaces of a prism beam splitter arrangement, a wiring carrier with integrated circuits, which include parts of the signal preprocessing electronics, being additionally provided on another side of the prism.
- JP-04214521 A it has further been proposed to form a beam splitter based on coated glass plates which are cast in a transparent resin block.
- mirror arrangements are used as beam splitters, however, there is the disadvantage that the imaging on the CCD receivers is reversed, which entails optical corrective measures.
- an object of the invention to provide an optical carrier and housing arrangement for receiving a color splitter system and a plurality of image converters, in particular CCD receivers, which can be miniaturized and which enables the use of unhoused CCD components. Furthermore, the support and housing arrangement should be realizable with low manufacturing costs and enable a high degree of prefabrication of the assemblies or components to be used in it.
- the basic idea of the invention is to start from a metallic or conductive and thus erodable housing block, which has a radiation entrance opening on one of the side surfaces and radiation exit openings on the other side surfaces.
- a metallic or conductive and thus erodable housing block which has a radiation entrance opening on one of the side surfaces and radiation exit openings on the other side surfaces.
- In the beam path there is a groove-shaped receptacle with corresponding ones inside the block
- Stop surfaces are provided for fixing a mirror filter color splitter system known per se.
- the mirror filter color divider system can be prefabricated and after visual inspection is inserted into the corresponding recess or the fastening grooves in the housing block and there e.g. fixed by gluing.
- CCD bare chips are preferably mounted in flip-chip technology on wiring support modules provided according to the invention.
- the optical carrier and housing arrangement according to the invention thus fulfills the function of holding the mirrors and filters of the color splitter system, fastening the CCD bare chips and holding the CCD control electronics.
- the combination of CCD chips, chip carriers, control electronics with housing and color splitter system is achieved via the described wiring carrier modules or the composite circuit board, whereby ceramic materials as well as plastic films or conventional FR4 circuit board material can be used as chip carrier materials.
- the bare chips are face-down on the carrier material using flip-chip technology e.g. contacted with conductive adhesive.
- Both the wiring support modules for the CCD bare chips and the rigid circuit board with CCD control electronics can be manufactured separately and subjected to the necessary electronic and other tests.
- Openings and recesses in the housing block can be ensured by using the wire EDM technology.
- Figure 1 is a plan view and side views of the housing block for receiving a color splitter system and several image converters.
- FIG. 2 shows a schematic diagram of a wiring carrier module for CCD bare chips in a top view and a side view
- Fig. 3 is a schematic representation of a
- Composite circuit board comprising a central Section for the CCD control electronics and at least three sections for receiving the CCD naked chips and associated head electronics.
- the housing block 1 shown in FIG. 1 has a radiation input 2 and three radiation output openings 3. Inside the housing block 1, fastening grooves 4 are provided for fixing a mirror filter color splitter system.
- the housing block 1 has an open top surface 5 with fastening bolts 6 provided there.
- Recesses 8 in particular in the area of the radiation exit openings 3 within the housing block 1, serve to accommodate further optical elements such as filters or lenses depending on the intended use of the overall arrangement or the CCD receivers used.
- the wiring support modules 9 shown in FIG. 2 in the form of individual circuit boards serve to fasten the necessary electronic components 10, but also to fix the CCD bare chip 11.
- the CCD bare chip 11 is flipped-chip technology face-down over an opening 12 in the wiring carrier 9, for example electrically and mechanically contacted by conductive adhesive.
- the correspondingly completed and tested wiring carrier modules 9 are then positioned with the opening 12 and the CCD bare chip 11 located there in front of the respective radiation exit openings 3 in the housing block 1, and are preferably fixed there with a material fit.
- a composite printed circuit board 13 is assumed, which has the necessary CCD control and evaluation electronics in a central section 14.
- the further sections 15 are then folded down over the flexible connection areas 17 in front of the respective radiation exit openings 3 in the housing block 1 and adjusted, positioned and fastened there.
- both the head electronics and the control electronics are system-integrated, the necessary adjustment between the CCD naked chip and the image can be carried out virtually online via the color splitter system, which leads to a reduction in the manufacturing costs and to a shortening of the manufacturing time.
- the optical carrier and housing arrangement with color splitter system and CCD receivers as image converter described with the above exemplary embodiment can preferably be used for miniaturized multi-chip CCD color cameras and can be used in endoscopy, laparoscopy or else in the intraoral area.
- the housing block itself can be designed as a standard module, as can the wiring supports and the composite circuit board, whereby it is possible to use CCD bare chips with different selectivity or other properties, but also to use differentiated color splitter systems and / or filter combinations in the housing block depending on the application.
