Abstract： |
The invention relates to the micro-digital sun sensing device and belongs to the attitude sensing device technology field. The sensing device comprises the light inducting device, the image collecting module composed of the image sensor, the attaching circuit an the image collecting control circuit, the image processing and communicating module. The light inducting device is layer-superposing structure with the narrow-belt or neutral optical filter, the transmission base plate, the mask layer and the glistening-proof layer from up to down. The mask layer adopts the small-hole array structure with unequal space; the small-hole array structure opens the square holes with two sizes, and the small holes and the rows of the different space appear alternatively. The invention can reduce the noise of the imaging circuit system and the random measuring error, and reduces the size, the energy consumption of the sensing device. |
