Scanning and interference imaging spectrometer are widely used in earth observing, microscope imaging, etc. Motion
mechanisms are utilized in all these simple imaging spectrometers, which make the system big, expensive and unstable.
A novel static non-imaging spectrometer is introduced specifically. 2D (two-dimension) static multi-channel spectral
measurement is realized in this spectrometer, utilizing 2D hadamard matrix code mask and 2D detector. The hadamard
matrix is different from traditional S circular code. The orthogonal property of hadamard matrix is utilized, and with
special transform negative codes in hadamard matrix are also realized. Basing on this non-imaging spectrometer static
imaging spectrometer is developed. First 2D imaging spectrometer can be divided into many 1D ones which work
independently. The 1D imaging spectrometer is obtained with position information added into the hadamard coding
system in dispersive direction. To get 2D imaging spectrometer, extend the coded aperture: put some masks together in
non-dispersive direction. According to this model, the spectrum of an image instead of a slit can be estimated at one
time. The optical system is designed to simulate the imaging spectrometer. Compared to the simple scanning imaging
spectrometer the simulated result shows the model's resolution can be compared to simple scanning spectrometer, but
the scanning time of simple scanning imaging spectrometer is about 3 times of our simulation. At last some
implementation issues are mentioned.
