Method and apparatus for generating an image of biomolecular sensor target area
View Patent ↗Method and apparatus for imaging a target area. Apparatus comprises an adjustable light emitting device that provides a light beam with a user defined spectrum. A filter mechanism receives the light beam and directs the light beam towards a target area. A light collection device collects an amount of light reflected from a target area and generates an image from the reflected light.
1. An apparatus for generating a biosensor image, said apparatus comprising:
a guided mode resonant sensor having a sub-wavelength grating structure;
a light source;
an adjustable monochromator optically coupled to said light source, said adjustable monochromator adjusting a spectrum of light from said light source to a define a narrow band of wavelengths that illuminate a surface of a biosensor target area on the sub-wavelength grating structure, said narrow band of wavelengths substantially centered at a target area PWV (peak wavelength value); and
a telecentric lens for received the narrow band of wavelengths reflected from said surface of said biosensor target area and generating an image of said biosensor target area.
2. The apparatus of claim 1 wherein said light source generates white light.
3. The apparatus of claim 1 wherein said light source comprises an LED.
4. The apparatus of claim 1 wherein said light source comprises a halogen light source.
5. The apparatus of claim 1 wherein said adjustable monochromator comprises a micrometer.
6. The apparatus of claim 5 wherein said micrometer comprises a manual micrometer.
7. The apparatus of claim 1 wherein said light source is optically coupled to said adjustable monochromator by a multimode fiber.
