Advanced synchronous luminescence imaging for chemical and medical diagnostics
First Claim
1. A diagnostic method, comprising the steps of:
- exposing at least one sample location with excitation radiation through a single optical waveguide or a single optical waveguide bundle, wherein said sample emits emission radiation in response to said excitation radiation;
receiving at least a portion of said emission radiation from said sample location in said single optical waveguide or said single optical waveguide bundle, wherein said single optical waveguide or said single optical waveguide bundle provides co-registration of said excitation radiation and said emission radiation, and synchronously scanning a wavelength of said excitation radiation and a wavelength of said emission radiation to produce a spectrum.

Abstract
A diagnostic method and associated system includes the steps of exposing at least one sample location with excitation radiation through a single optical waveguide or a single optical waveguide bundle, wherein the sample emits emission radiation in response to the excitation radiation. The same single optical waveguide or the single optical waveguide bundle receives at least a portion of the emission radiation from the sample, thus providing co-registration of the excitation radiation and the emission radiation. The wavelength of the excitation radiation and emission radiation is synchronously scanned to produce a spectrum upon which an image can be formed. An increased emission signal is generated by the enhanced overlap of the excitation and emission focal volumes provided by co-registration of the excitation and emission signals thus increasing the sensitivity as well as decreasing the exposure time necessary to obtain an image.
