Confocal scanning laser ophthalmoscope

Applied Optics, 1987
A confocal scanning imager moves an illumination spot over the object and a (virtual) detector synchronously over the image. In the confocal scanning laser ophthalmoscope this is accomplished by reusing the source optics for detection. The common optical elements are all mirrors-either flat or spherical-and the scanners are positioned to compensate ...

Scanning Laser Ophthalmoscope Microperimetry

Seminars in Ophthalmology, 1998
In this article, the methodologies and clinical applications of microperimetry performed by scanning laser ophthalmoscope (SLO) are described. This technique provides functional results by direct visualization of the macular area. We present the most interesting data about clinical applications in ocular pathology.

Scanning Laser Cytometry

Current Protocols in Cytometry, 2004
AbstractThere are many tasks to which flow cytometers are unsuited, e.g., measurement of attached cells, repeated measurements of a single cell over time, and localization of probes in or on cells. Devices such as confocal microscopes and microscope‐based imaging systems allow high‐resolution analysis and provide flexibility, but typically have low ...

Rapid-scanning laser receiver

Applied Optics, 1975
A random-access rapid-scanning laser receiver concept utilizing the acoustooptic effect and suitable for applications from the near uv through the long-wave ir region was designed and demonstrated in the field at a 10.6-microm laser radar. Experimental results demonstrating its utility for image detection, radar, atmospheric optics measurements, and ...

Digital scanning laser microscope

Applied Optics, 1985
A digital scanning laser microscope system, capable of scanning a specimen at high speed, has been developed. The system can display a reflected, transmitted, or photoinduced mode of the scanning laser micrograph size 512 × 512 pixels on a conventional TV monitor within 10 sec.

Adaptive Laser Range Scanning

2007 International Workshop on Robotic and Sensors Environments, 2007
We present an approach to laser range scanning in which quality metrics are used to automatically reduce the number of measurements acquired from a scanner viewpoint. As part of this approach we present improved versions of the orientation, and reflectivity quality metrics, as well as introduce three quality metrics: spot size, re solvability, and ...

Scanned Laser Infrared Microscope

Applied Optics, 1970
In examination of ir-transmitting materials, internal irregularities and inclusions of foreign material can be detected by their effect upon the ir transmittance of the material. A scanning laser ir microscope has been constructed which produces, on an oscilloscope display, a shadowgraph picture of the ir transmittance of the material under examination.

The scanning laser ophthalmoscope

Physics in Medicine and Biology, 1997
The imaging of the fundus of the eye poses two major technical challenges. First, it is necessary for both the illuminating and reflected beams to pass through the same aperture, the iris. In some commonly used instruments this leads to the use of levels of illumination close to the maximum tolerable by a patient.

Scanning laser polarimetry – a review

Clinical & Experimental Ophthalmology, 2009
AbstractGlaucoma is a leading cause of irreversible blindness worldwide. Retinal ganglion cells and their axons represent the selective target of the disease. When visual function is still intact on standard automated perimetry and optic disc appearance is suspicious, an early diagnosis may be supported by the identification of a retinal nerve fibre ...

Holographic Laser Scanning Microscopy

2017
We realize a new optical microscopy technique (Holographic Laser Scanning Microscopy, H-LSM) based on holographic laser scanning illumination of the sample. In each scanning step, a multispot illumination pattern is generated by phase modulating a laser beam via Computer Generated Holography (CGH).
