A system and method for multi-chromatic imaging that requires a single detector are described. A light source sequentially produces multiple light wavelengths for illumination of a subject. An optical filter filters the light wavelengths, and directs them to the subject, and then filters the transmitted or reflected light, and directs it to an image detector. The image detector sequentially receives each transmitted or reflected light wavelength with a different frame or field, and then produces an detected image signal for an analyzer. A video sync separator separates the composite video image signal from the image detector into the signal components necessary for sequencing the light source. A sequence driver uses these separated signal components to create sequencing signals for driving the light source. These sequencing signals keep the wavelengths produced by the light source synchronized with the respective frames or fields of the image detector
