An onboard model of a TV camera to detect spectroscopically resolved images has been developed. It has been able to detect several spectral pictures at the same time by using only one camera with no restriction against spectral selection between each picture. The wavelength of each picture has been selected electronically. The number of spectroscopically resolved pictures is dependent only on the memory size of the computer. This camera is equivalent to a standard TV camera in which 117 bandpass filters are installed. The favorable characteristics of this camera are that it does not cause a time difference between each picture and is able to display the physical parameters by numerical calculations and can change the spectral range even after launch. The principal purpose of this model is to assist in investigating the dynamic structure of the aurora and the atmospheric composition of planets.
