High-Resolution Light-Field Microscopy

By combining a high-resolution image from a standard camera with a low-resolution wavefront measurement from a Shack-Hartmann sensor, we numerically reconstruct a highresolution light field. We experimentally demonstrate the method with a commercially available microscope. ©2013 Optical Society of America OCIS codes: (110.0180) Microscopy; (110.1758) Computational imaging; (100.6640) Superresol...

High Resolution Millimeter-wave Mapping of Linearly Polarized Dust Emission: Magnetic Field Structure in Orion

We present 1.3 and 3.3 mm polarization maps of Orion-KL obtained with the BIMA array at approximately 4′′ resolution. Thermal emission from magnetically aligned dust grains produces the polarization. Along the Orion “ridge” the polarization position angle varies smoothly from about 10◦ to 40◦, in agreement with previous lower resolution maps. In a small region south of the Orion “hot core,” how...

High-resolution imaging with field-emission SEM: the need for downstream plasma cleaning in biological applications

For high-resolution visualization and image capturing of biological samples, the cleanliness of the high-vacuum imaging environment, including both instrument and sample surface, have become important aspects to ensure electron beam stability and high signal-to-noise ratios (SNR). Regular downstream plasma cleaning of both SEM chamber and specimen is required to ensure an uncontaminated instrum...

High resolution ultrastructural investigation of insect sensory organs using field emission scanning electron microscopy

Field emission scanning electron microscopy (FESEM) is an extremely useful viewing technique for examining ultrastructural features pertaining to insect sensory organs (sensilla) at high magnifications. In comparison to conventional scanning electron microscopy (SEM), FESEM operates superiorly at lower accelerating voltages, offering greater resolution capabilities at higher magnifications and ...
