Abstract

The compound-tomography imaging spectrometer (CTIS) captures a scene's spatial and spectral information without any type of scanning. This capability enables a variety of applications that require spectral imaging of transient events. In this work, we demonstrate a flexible CTIS calibration techniques that allows multiple scene resolutions to be reconstructed from a single detector frame. The technique combines measurements with simulations to determine the transfer matrix of the system. Reconstructions of an experimental scene are performed to demonstrate the flexibility of the approach.
