ファイバー１１は。When one line sensor is used, the following formula holds true: 1, m B d For example, if the minimum ground resolution dm is 30 m and the number n of CCD cables is 2048, the scanning width will be approximately 61.4-. t
However, from the satellite's Mitsushicon requirements, the wider the scanning width, the more advantageous it is for operation, and the smaller the minimum ground resolution d, the more accurate the accuracy can be obtained. Due to these requirements, it is desirable to have several CCDCD devices with seven lines ψ, but there are many difficulties in manufacturing the device. Furthermore, as a method of increasing the scanning width using a line sensor with a small number of elements, the third factor C
It is conceivable to arrange the line sensors 9°9 in a staggered arrangement, as in Japan, but it would be better to set the viewing direction of the CCD of each line sensor f9.9 separately! It also has the disadvantage of requiring 62 separate peripheral circuits for each line sensor 9°9.@Moe's purpose Large capacity -1g, which was difficult to achieve with conventional line cet+ sensors. One-dimensional detection (for example, hundreds of thousands of pixels) is possible! ms of the invention In other words, the present invention provides a -dimensional/two-dimensional array side! lIv? The two-dimensionally arrayed side ends rkU of the optical fiber bundle 'T' are joined, and the one-dimensionally arrayed side end of the optical fiber bundle becomes a large-capacity element one-dimensional light-receiving surface. An embodiment of the present invention will be described in detail with reference to the inner surface.In the fourth factor, io is a two-dimensional CCD image sensor, and 11 is an optical fiber bundle.This optical fiber 11 is.

The end surface on the two-dimensional array side is joined to the light receiving section 11 of the image sensor 10, and the end surface on the -dimensional array side is the light receiving surface IM.
, shows the principle of realizing a one-dimensional detector with nine clouds using a two-dimensional CCD image sensor consisting of a three-pixel CCD in both the Y direction.Here, 14 is an optical fiber bundle, il
is the two-dimensional side edge (1, ti is the one-dimensional side ground). According to the above configuration, if a 400×400 element, which is currently in practical use as a two-dimensional COD image sensor 10, is used, the number of particles per gram is A one-dimensional detector of 160,000 can be realized. This means that the number of elements in a line CCD centimeter is currently 2,048, which is the largest at a practical level. C: Considering this, it has a very large capacity.
- It should be noted that the two-dimensional CCD image sensor fill shown in the 4th factor is not limited to a specific method 4, but the well-known frame transfer method, interline method, and thermal image sensor V- ! I feel like the in-method is at a loss =
Also applicable is the one-dimensional to two-dimensional conversion array of the optical fiber bundle 11≦; in this regard, the specific array C: is not limited to the most advantageous for signal processing of the two-dimensional CCU image sensor flu. Effects of the Invention As mentioned above, according to the present invention C2, one-dimensional detection of hundreds of thousands of samples from the enemy, which was difficult with the conventional CCD line sensor. By using such a -dimensional detector such as a visible near-infrared emitting nail for remote sensing at a ratio of 1:4, it is possible to obtain high resolution and wide scanning width. You can configure your own devices.
