The present invention relates to a quad-partitioned radiation sensor and, more specifically, to a quad-partitioned radiation sensor capable of measuring solar altitude in a wide range that a quad-partitioned radiation sensor may accurately measure altitude even when solar altitude is low. The quad-partitioned radiation sensor comprises: a light receiving element having a quad-partitioned light receiving surfaces; and a mask disposed on top of the light receiving element and having an incidence area in the center. The quad-partitioned light receiving surfaces of the light receiving element has the same area receiving light when vertical light is incident on the incidence area of the mask, but adjacent light receiving surfaces are formed asymmetrically with each other.
본 발명은 4분할 일사센서에 관한 것으로서, 특히 태양의 고도가 낮은 경우에도 고도를 정확히 측정할 수 있는 등 넓은 범위의 태양 고도의 측정이 가능한 4분할 일사센서에 관한 것으로서, 4분할된 수광면을 갖는 수광소자와, 상기 수광소자의 상측에 배치되고 중앙에 입사영역이 형성된 마스크를 포함하고, 상기 수광소자의 4분할된 수광면은 상기 마스크의 입사영역에 수직광이 입사될 때 수광되는 수광면의 면적은 동일하나 인접한 수광면들이 서로 비대칭으로 형성되는 것을 특징으로 한다.
