The schematic diagram of the light detection method of the planar array light detection device is shown in the first diagram. The main difference is that the light detection device 150 is a planar array light detection device.

The planar array photodetection device 2 10 referred to in the present invention refers to a light detection device including a planar array light sensing unit 2 11, such as a planar array charge coupled device (Focal plane array charge CQupied device). ) Is one of them, which contains the number of sensing units 211, which can be amplified according to the sensing accuracy and resolution. < 200422590 V. Description of the invention (4) In the second illustration, each sensing unit 211 is represented by a small square. 'If the container 121 is not tilted, the center point of the focusing beam 140 should be located at 0. The center sensing unit 2 1 2 is used, but in this example, since the container 1 21 is assumed to be partially inclined, the focused light beam 丨 4 〇 The focused center point is located on the sensing unit 213 labeled 1. Therefore, in When using this device, first use the electronic signal processing method to obtain the focused position of the focused light beam 140 (the sensing unit 213 of 1), and then calculate the relative position of the central sensing unit 212 of 0 and the sensing unit 21 of 1 The position difference, that is, the amount of position deviation, can be used to convert the value and orientation of the tilt angle of the container. Please refer to FIG. 3 for the second embodiment of the present invention. The schematic diagram of the light detection method of the four-quadrant photodetection device is shown in FIG. 1, and the light detection device 150 is a four-quadrant photodetection device 31. Similar to the above. In the first embodiment, a side view (left) and a front view (enlarged right) of the focused light beam 140 and the four-quadrant photodetection device 310 at the same time are indicated in the figure. In the second embodiment, the so-called four-quadrant photodetection device 31 〇 refers to a light-detection device 150 including a four-quadrant sensing unit 311. Each quadrant sensing unit 311 can be provided with a linear mask 3 symmetrical to the center point 3. 1 2. b linear mask 31 3, c linear mask 314, d linear mask 31 5. Each of the linear masks contains a uniformly diffusing substance of light, which can cause the focused light beam 140 projected into the linear mask to be uniformly sensed by each quadrant sensing unit 311, and the focused light beam projected outside the linear mask 140. Block. This linear mask acts to make the quadrant sensing unit 311's photosensitive intensity proportional to the intensity per unit area of incident light and the length of the linear direction of the incident light projected into the linear mask. In this embodiment, due to the four-quadrant light detecting device 3130 detecting position deviation
200422590 五、發明說明（5) 差量方式與入射聚光光束140光強度均勻性有關，在此假 設入射聚光光束140為一均勻聚光光束，其入射聚光光束 140單位面積光強度一致，不隨入射位置而改變。 當聚光光束1 4 0投射於各象限感測單元311時，均需經 過線性遮罩，若容器121未傾斜，則聚光光束140聚光中心 點應位於四象限檢光裝置3 1 〇中心點上，但本實施例中，200422590 V. Description of the invention (5) The difference method is related to the uniformity of the light intensity of the incident spotlight beam 140. It is assumed here that the incident spotlight beam 140 is a uniform spotlight beam, and the incident spotlight beam 140 has a uniform light intensity per unit area. Does not change with the incident position. When the focused light beam 140 is projected onto each quadrant sensing unit 311, all need to pass a linear mask. If the container 121 is not tilted, the focused center of the focused light beam 140 should be located at the center of the four-quadrant light detection device 3 1 〇 Point, but in this embodiment,
假設容器121有部份傾斜（沿著a線性遮罩312及c線性遮 罩314線性方向），使聚光光束丨4〇聚光中心點偏向c線性 遮罩314，因此，若求得c線性遮罩314内感測單元31ι感 測得光強度（設為Ic)，及a線性遮罩312内感測單元311感 測得光強度（設為I a )，其光強度差（I c -1 a)正比於位置偏 差量’而其位置偏差量正比於tan Θ，因此若測得此一光 強度差，即可測得此一方向之傾斜角度值。 同理’若另一方向（沿著b線性遮罩31 3及d線性遮罩 315線性方向）亦有部份傾斜時，只要求得d線性遮罩315 内感測單元311感測得光強度（設為I d )，及b線性遮罩31 3 内感測單元311感測得光強度（設為I b )，測得其光強度差 (Id-lb)，即可測得此一方向之傾斜角度值。此二方向之 傾斜角度值經由電子訊號處理單元作數學運算，即可求得 容器121實際之傾斜方向及實際之傾斜角度值。 以上已將本發明做一詳細說明，惟以上所述者，僅為 本發明之較佳實施例而已，當不能限定本發明之實施範… 圍。即凡依本發明申請範圍所做之均等變化與修飾等，皆 應仍屬本發明之專利涵蓋範圍内。Assume that the container 121 is partially inclined (along the linear direction of a linear mask 312 and c linear mask 314), so that the focused light beam center 40 is biased toward c linear mask 314. Therefore, if c linear is obtained The light intensity (set to Ic) sensed by the sensing unit 31m in the mask 314, and the light intensity (set to Ia) sensed by the sensing unit 311 in the a linear mask 312, the light intensity difference (I c- 1 a) It is proportional to the position deviation amount and its position deviation amount is proportional to tan Θ. Therefore, if the light intensity difference is measured, the tilt angle value in this direction can be measured. Similarly, if the other direction (along the linear direction of b linear mask 31 3 and the linear direction of d linear mask 315) is also partially tilted, only the d linear mask 315 is required to detect the light intensity detected by the inner sensing unit 311. (Set to I d), and b linear mask 31 3 inner sensing unit 311 senses the light intensity (set to I b), and measures the light intensity difference (Id-lb) to measure this direction The tilt angle value. The inclination angle values of the two directions are mathematically calculated by the electronic signal processing unit, and the actual inclination direction and the actual inclination angle value of the container 121 can be obtained. The present invention has been described in detail above, but the above are only preferred embodiments of the present invention, and the scope of the present invention cannot be limited. That is, all equivalent changes and modifications made in accordance with the scope of the application of the present invention shall still fall within the scope of the patent of the present invention.
