IMAGE PICKUP DEVICE AND SOLID-STATE IMAGE PICKUP ELEMENT OF THE TYPE ILLUMINATED FROM BOTH FACES
摘要
<p>Disclosed is an image pickup device wherein a plurality of photosensitive cells are provided between the first face (30a) of a semiconductor layer and the second face (30b) which is positioned at the back of the first face, so that photoreception is possible not only from the first face (30a) but also from the second face (30b). The image pickup device is provided with an optical system (300) including an optical element (9) that divides incoming light into a first beam and a second beam. The optical system (300) is constituted so that the first beam is directed onto the first face (30a) and the second beam is directed onto the second face (30b).</p>
