Definitions
- the invention relates to an arrangement for increasing the spatial resolution of radiation detectors, which can be used in all detectors which have a single radiation receiver surface or a plurality of radiation receiver surfaces which are arranged in a plane at a periodic spacing. All flat photoelectric receivers such as e.g. CCD's, bolometers, thermopiles etc. into consideration.
- the input elements of an imaging system are usually modified in such a way that the pixel areas of the receiver elements are reduced.
- the increase in resolution is limited by the available pixel sizes in connection with their number and costs.
- a solution according to EP 0 336 152 A1 is only indirectly related to the present invention, in which a single gap system is positioned at a relatively large distance in front of a receiver, which contains several receiver surfaces at different distances from one another. This solution is used exclusively for the detection of the direction of incidence of radiation with which the single slit is illuminated.
- the present invention is based on the object of specifying an arrangement for increasing the spatial resolution of conventional radiation detectors, which enables a variable increase in spatial resolution and manages with a few modules.
- FIG. 1 shows an arrangement for increasing the spatial resolution with all essential assemblies
- FIG. 1 a schematically shows a receiver element with an associated one
- FIG. 2 shows, by way of example, the intensity curve of a mercury line
- FIG. 4 shows the intensity distribution of the line from the intensity distribution according to FIG. 3 in one
- Evaluation unit arithmetically determined intensity profile of the intensity distribution obtained according to FIG. 3,
- FIG. 5 shows an embodiment of a multiple web arrangement for a two-dimensional radiation detector
- FIG. 6 shows an embodiment of a multiple web arrangement for a one-dimensional radiation detector with a possibility of varying the spatial resolution increase.
- FIG. 1 shows a radiation detector which contains, by way of example, five receiver surfaces 1, for which photoelectric receivers are selected in the example, at an equidistant distance. These receiver surfaces are illuminated in accordance with the arrows S shown with radiation that can be detected by the receivers. If the radiation has an intensity distribution, as indicated by way of example in FIG. 2, each individual receiver surface 1 supplies only an integral signal corresponding to the intensity. The distribution in the area of the recipient area is not resolved. This is where the invention comes in, in that each individual receiver surface is assigned a web 2, which is not transparent to the radiation used, at a distance of the order of the web width. At such a distance, the aperture of the lighting has no noticeable influence on the shadowing effect of the web, so that a high contrast between the illuminated and shadowed
- the web width ba is preferably set to be an integer fraction of the receiver width.
- the Web 2 or webs 2 in several discrete positions from a starting position denoted by 2a in Figure la in an end position 2e, so that the entire receiver surface 1 is detected at least once.
- the finer the web width ba is defined in relation to the width of the receiver surface, the greater the resolution.
- a spatial resolution increase by a factor of 5 compared to the receiver is achieved without the proposed arrangement.
- the signal-to-noise ratio is significantly improved compared to conventional arrangements.
- FIG. 5 shows a further possibility of web formation, in which a matrix of photoelectric receivers, consisting of three rows of five receiver elements each, is used.
- the arrangement of the webs 21 corresponds to the arrangement according to FIG. 1.
- the webs 22 are arranged in an analogous manner, but perpendicular to the webs 21.
- the measured value acquisition and displacement of the webs 21 is carried out first, as described for FIG. 1, the webs 22 being brought into a position in which they do not act on the receiver surfaces, then the webs 21 are in the position shown in FIG. 5 spent and in the simplest case there is only a displacement of the webs 22; other scan sequences are within the scope of the invention.
- two-dimensional intensity profiles with increased spatial resolution can be detected on the matrix.
- FIG. 6 Another possibility of training the webs is shown schematically in FIG. There, in turn, it is to be assumed that there are five receiver surfaces arranged in a row, not shown in FIG. 6, to which five webs 21a are assigned. Furthermore, a second set of webs 21b is provided, the width of which is somewhat widened compared to the webs 21a, as a result of which a reduced resolution is achieved when they are used, which may be sufficient for some measuring tasks. If several such sets of different web widths are made available, the desired increase in the spatial resolution can be specified by appropriate selection of the sets and / or the step size.
- the webs 2, 21, 22 are preferably formed by introducing recesses 71 into a silicon membrane by means of microsystem technology methods.
- the webs and a silicon frame 7 which surrounds them remain, which in turn is grasped by a receptacle (not shown in more detail) and is connected to the adjusting element 3.
