    Abstract: PROBLEM TO BE SOLVED: To obtain a spectral video system which can speedily obtain data and has high resolution. SOLUTION: This system is equipped with a light source 110, an optical modulating means 120 which forms a lighting aperture and guides a predetermined lighting pattern to make the position of an object of inspection conjugate, and an analyzing means 150 equipped with a detection aperture, a spectral dispersing element, and a detector camera 156. Then the lighting and detection apertures are arranged on a conjugate plane and the optical modulating means 120 consists of a two-dimensional array of optical modulating elements; and the groups of the elements constituting the two-dimensional array are arranged so as to form the lighting aperture according to the lighting pattern and the optical modulating element 120 is so controlled that the lighting pattern varies the conjugate position of the object depending upon the time.
