PURPOSE:To obtain a wide visual sight with the use of an optical system of a narrow angle by arranging a plane mirror and a linearly arranged photoelectric conversion detector one by one by one correspondence and combining each plane mirror with linearly arranged photoelectric conversion detector so as to provide a different visual field from each other. CONSTITUTION:The plane reflecting mirrors 6-8 are coupled with the linearly arranged photoelectric conversion detectors C1-C3 one by one, its normal spectrum is directed in different direction with each other t constituted respectively visual fields V1-V3 thereby obtaining a wide visual field expressed as S1+S2+S3. In this case, since the arranging direction of the linearly arranged photoelectric conversion detectors C1-C3 is made orthogonal in the element arranging direction in the inside of each converter, for example, the wide angle of visual field is compressed within a narrow visual field. Since no mechanical moving part is needed, a video sensor with high reliability is realized. Since no optical system having a wide angle characteristic is required, the constitution of the optical system is simple and the weight is reduced. |
