All-optical adaptive scanning acoustic microscope

All-Optical Scanning Acoustic Microscope

In this thesis a new instrument, the all-optical scanning acoustic microscope (O-SAM) is presented, it is a non contact scanning acoustic microscope (SAM) which uses lasers to both generate and detect surface acoustics waves (SAWs) The non contact nature of the O-SAM overcomes some difficulties associated with conventional SAMs because of the couplant and surface contact involved. This O-SAM al...

The Scanning Optical Microscope

Instead of forming an entire image at one instant, a scanning optical microscope (SOM) scans a beam of light across specimen in a regular pattern, or raster, and forms its image point by point. A point of light is focused to a diffraction-limited spot on the sample by the objective lens. An image is built up point by point by a detector, either below the slide (if the microscope is exclusively ...

Adaptive Scanning Optical Microscope (ASOM): A multidisciplinary optical microscope design for large field of view and high resolution imaging.

From micro-assembly to biological observation, the optical microscope remains one of the most important tools for observing below the threshold of the naked human eye. However, in its conventional form, it suffers from a trade-off between resolution and field of view. This paper presents a new optical microscope design that combines a high speed steering mirror, a custom designed scanner lens, ...
