A custom confocal and two-photon digital laser scanning microscope.
We describe a custom one-photon (confocal) and two-photon all-digital (photon counting) laser scanning microscope. The confocal component uses two avalanche photodiodes (APDs) as the fluorescence detector to achieve high sensitivity and to overcome the limited photon counting rate of a single APD ( approximately 5 MHz). The confocal component is approximately nine times more efficient than our ...
متن کاملA Digital ULSI Inspection Method Using Parallel Scanning Confocal Microscope
In ULSI fabrication, the design rule scaled up to 0.25um and the complex multiple layer structure prevent from applying the traditional optical microscope of which resolution is about 0.4um. Considering the situation, we have developed a ULSI inspection system based on the scanning parallel confocal microscope. In this paper, we present the feature of the computer aided parallel scanning confoc...
متن کاملGeneralizing the Confocal Microscope via Heterodyne Interferometry and Digital Filtering
We describe a generalized confocal optical microscope which measures both phase and amplitude, separately and simultaneously. The system is based on heterodyne interferometry, and is extremely fast and accurate. Together with the associated signal processing and data acquisition system, it can take data at the rate of 50,000 points per second, to an accuracy of 12 bits in amplitude and about th...
متن کاملModular Scanning Confocal Microscope with Digital Image Processing
In conventional confocal microscopy, a physical pinhole is placed at the image plane prior to the detector to limit the observation volume. In this work, we present a modular design of a scanning confocal microscope which uses a CCD camera to replace the physical pinhole for materials science applications. Experimental scans were performed on a microscope resolution target, a semiconductor chip...
متن کاملConfocal laser microscope.
The confocal laser microscope is a novel and interesting noninvasive tool for imaging skin lesions and subsurface skin lesions that are not visible to the naked eye or even by dermoscopy. Skin can be imaged in vivo or freshly biopsied (in vitro) skin specimens can be visualized immediately without the processing that is required for routine histopathology. Dynamic events (real time imaging) in ...
