ABSTRACT:
A method and apparatus for illuminating a subject with deep UV light and detecting 2-dimensional image information, e.g., a transmission image, fluorescence image, reflected light image, etc. The subject may be illuminated with a light pulse having a duration of 2 seconds or less and one or more components with a wavelength of between about 150 nm to about 300 nm. The light pulse may be arranged so as to minimize or eliminate any detrimental effect on the functioning of the subject, e.g., on a living cell. A concentration, mass, quantum yield, absorbance or other characteristics of one or more compounds in the subject may be determined based on one or more 2-dimensional images obtained of the subject. An illumination beam having left and right circularly polarized components may be generated, e.g., for circular dichroism analysis of a subject.
