Claim 0:
1. A system comprising:
an emitter that emits a plurality of pulses of electromagnetic radiation according to a variable pulse cycle, wherein the emitter comprises a plurality of separate spectral sources that are each tuned to emit electromagnetic radiation within a waveband selected for multispectral visualization;
an image sensor that accumulates electromagnetic radiation and reads out data according to a sensor cycle; and
a controller in electronic communication with the emitter and the image sensor;
wherein the emitter comprises:
a first spectral source tuned to emit a first spectral waveband of electromagnetic radiation at a first dichroic mirror, wherein the first dichroic mirror reflects the first spectral waveband into an optical fiber bundle at an angle that is substantially perpendicular to an angle of emission from the first spectral source;

a second spectral source tuned to emit a second spectral waveband of electromagnetic radiation at a second dichroic mirror, wherein the second dichroic minor that reflects the second spectral waveband into the optical fiber bundle at an angle that is substantially perpendicular to an angle of emission from the second spectral source such that the second spectral waveband passes through the first dichroic mirror; and
a third spectral source tuned to emit a third spectral waveband of electromagnetic radiation at a third dichroic mirror, wherein the third dichroic minor reflects the third spectral waveband into the optical fiber bundle at an angle that is substantially perpendicular to an angle of emission from the third spectral source such that the third spectral waveband passes through at least one of the first dichroic minor or the second dichroic minor;
wherein the first dichroic minor is transparent to each of the second spectral waveband and the third spectral waveband;
wherein the second dichroic mirror is transparent to the third spectral waveband; and
wherein each of the first dichroic minor, the second dichroic mirror, and the third dichroic minor is oriented at an angle that is offset from perpendicular relative to a collection region of the optical fiber bundle;
wherein each of the first spectral waveband, the second spectral waveband, and the third spectral waveband is a different waveband selected to elicit a spectral response from a tissue.
