Abstract: A new technique for imaging spectrometer for rotary object based on
computed-tomography is proposed. A discrete model of this imaging spectrometric
system is established, which is accordant to actual measurements and convenient
putation. puter simulations with this method, projections of the
object are detected D while the object is rotating, and the original spectral
images are numerically reconstructed from them by using the algorithm of
computed-tomography. Simulation results indicate that the principle of the method
is correct and it performs well for both broadband and narrow-band spectral
objects.
