Abstract: We describe fluorescence spectral-imaging results with the microscope computed-tomography imaging spectrometer ($mu@CTIS). This imaging spectrometer is capable of recording spatial and spectral data simultaneously. Consequently, the $mu@CTIS can be used to image dynamic phenomena involving multiple, spectrally overlapping fluorescence probes. The result presented in this paper consists of proof-of-concept imaging result using two static targets. The first is composed of 6-$mu@m fluorescing microspheres and the second consists of rat sinusoid epithelial cells loaded with 0.5-$mu@m fluorescing microspheres. Image data were collected in integration times of 16 msec, comparable to video frame rate integration times. The emission spectra were sampled at 10-nm intervals between 420 nm and 710 nm. The smallest spatial sampling interval presented in this paper is 1.7 $mu@m. !19
