Nanometric depth resolution from multi-focal images in microscopy

Nanometric depth resolution from multi-focal images in microscopy

We describe a method for tracking the position of small features in three dimensions from images recorded on a standard microscope with an inexpensive attachment between the microscope and the camera. The depth-measurement accuracy of this method is tested experimentally on a wide-field, inverted microscope and is shown to give approximately 8 nm depth resolution, over a specimen depth of appro...

Resolution improving method from multi-focal omnidirectional images

The omnidirectional image sensor named HyperOmniVision, is composed of hyperboloidal mirror and conventional video camera. It can observt: 360 degree field of view and can transform an input image to a perspective image. However, it has an intrinsic problem where the image resolution of HyperOmniVision is lower than that of an ordinary video camera, because of its structure that only one CCD ca...

STED microscopy reveals crystal colour centres with nanometric resolution

Because they have spin states that can be optically polarized and detected, fluorescent nitrogen vacancies in diamond1–3 have considerable potential for applications in quantum cryptography4,5 and computation6–8, as well as for nanoscale magnetic imaging9,10 and biolabelling11,12. However, their optical detection and control are hampered by the diffraction resolution barrier of far-field optics...
