Abstract:
An optical interrogation system and method are described herein that are capable of generating light beams that have desired optical properties which are directed towards a specimen array. In one embodiment, the optical interrogation system includes a light source, a diffractive element and a collimating optic (e.g., simple lens(es), f-θ lens(es), segmented mirror, fiber array). The light source emits a light beam to the diffractive optic which receives the light beam and outputs an array of light beams to the collimating optic. The collimating optic receives and conditions the light beams emitted from the diffractive optic and then outputs the conditioned light beams which have desired optical properties towards a specimen array. Several other embodiments of the optical interrogation system are also described herein.

Abstract:
A sensing probe may be formed of a diamond material comprising one or more spin defects that are configured to emit fluorescent light and are located no more than 50 nm from a sensing surface of the sensing probe. The sensing probe may include an optical outcoupling structure formed by the diamond material and configured to optically guide the fluorescent light toward an output end of the optical outcoupling structure. An optical detector may detect the fluorescent light that is emitted from the spin defects and that exits through the output end of the optical outcoupling structure after being optically guided therethrough. A mounting system may hold the sensing probe and control a distance between the sensing surface of the sensing probe and a surface of a sample while permitting relative motion between the sensing surface and the sample surface.
