Influence of EDM Parameters on the Appearance of Recast Layer [PDF]

open access: yesEngineering and Technology Journal, 2017
Electrical discharge machining (EDM) is one of non-traditional methods employed to produce complicated forms of electrical conductive materials. This process can be applied to materials difficult to machine with traditional methods.

Light-sheet microscopy: a tutorial [PDF]

open access: yes, 2018
This paper is intended to give a comprehensive review of light-sheet (LS) microscopy from an optics perspective. As such, emphasis is placed on the advantages that LS microscope configurations present, given the degree of freedom gained by uncoupling the

Optical contrast in near-field techniques [PDF]

open access: yes, 1995
In this paper results of experiments with a scanning near-field optical microscope with shear-force feedback are presented. The setup will be described and the shear-force signal as function of distance is shown.

Laser nanotraps and nanotweezers for cold atoms: 3D gradient dipole force trap in the vicinity of Scanning Near-field Optical Microscope tip [PDF]

open access: yes, 2005
Using a two-dipole model of an optical near-field of Scanning Near-field Optical Microscope tip, i. e. taking into account contributions of magnetic and electric dipoles, we propose and analyze a new type of 3D optical nanotrap found for certain ...

Automatic Optical Path Alignment Method for Optical Biological Microscope

open access: yesSensors
A high-quality optical path alignment is essential for achieving superior image quality in optical biological microscope (OBM) systems. The traditional automatic alignment methods for OBMs rely heavily on complex masker-detection techniques.

In-situ observation of graphene using an optical microscope

open access: yesApplied Surface Science Advances, 2021
In-situ observation of graphene by using visible light was very few. Herein, we investigate the feasibility of in-situ observation of graphene decomposition by using the optical microscope (OM) equipped with a heating vacuum stage.

An apertureless near-field microscope for fluorescence imaging [PDF]

open access: yes, 2000
We describe an apertureless near field microscope for imaging fluorescent samples. Optical contrast is generated by exploiting fluorescent quenching near a metallized atomic force microscope tip.
