Abstract
Systems and methods are provided for multi-spectral or hyper-spectral fluorescence imaging. In one example, a spectral encoding device may be positioned in a detection light path between a detection objective and an imaging sensor of a microscope. In one example, the spectral encoding device includes a first dichroic mirror having a sine transmittance profile and a second dichroic mirror having a cosine transmittance profile. In addition to collecting transmitted light, reflected light from each dichroic mirror is collected and used for total intensity normalization and image analysis.
