Abstract: Embodiments of the present invention relate a nondiffracting beam detection module for generating three-dimensional image data that has a surface layer having a first surface and a light transmissive region, a microaxicon, and a light detector. The microaxicon receives light through the light transmissive region from outside the first surface and generates one or more detection nondiffracting beams based on the received light. The light detector receives the nondiffracting beams and generates three-dimensional image data associated with an object located outside the first surface based on the one or more detection nondiffracting beams received. In some cases, the light detector can localize a three-dimensional position on the object associated with each detection nondiffracting beam received.

Abstract: Embodiments of the present invention can resolve molecules beyond the optical diffraction limit in three dimensions. A double-helix point spread function can be used to in conjunction with a microscope to provide dual-lobed images of a molecule. Based on the rotation of the dual-lobed image, the axial position of the molecule can be estimated or determined. In some embodiments, the angular rotation of the dual-lobed imaged can be determined using a centroid fit calculation or by finding the midpoints of the centers of the two lobes. Regardless of the technique, the correspondence between the rotation and axial position can be utilized. A double-helix point spread function can also be used to determine the lateral positions of molecules and hence their three-dimensional location.

Abstract: A method for fabricating millimeter and sub-millimeter size lenses using a high viscosity curable liquid, such as epoxy. The method comprises dispensing a predetermined volume of the curable liquid onto a substrate. The curable liquid preferably has a viscosity higher than 100 cps. Additionally, to reduce spherical aberration, the curable liquid can be cured upside down to leverage the effects of gravity.
