“…As the sample probe beams pass through the Bragg cell twice, this means losses of more than 60%. Furthermore, driving the Bragg cell with two frequencies leads to several spurious signals and beams, caused by both internal acoustic reflections and intermodulation products (Appel & Somekh, 1993). These spurious interference signals often dominate the desired signal by up to 30 dB before filtering.…”

Differential phase microscopy has proved invaluable in the study of live, unstained, thin biological samples because of its ability to image changes in refractive index and topography. Similarly, because of its optical sectioning capability, confocal microscopy is now a well‐established technique in the study of relatively thick live biological samples. This paper describes the development and application of two differential phase heterodyne confocal microscopes, and compares their performance. The use of these systems for imaging in‐vitro cell and tissue cultures is considered and compared with confocal reflection microscopy. It is demonstrated that the differential phase capability reveals subcellular structural information not readily seen in the confocal reflection images. This technique opens up the possibility of imaging thick unstained live tissues, avoiding cell damage and artefacts associated with staining procedures. Furthermore, the differential phase images can be used to provide a visual frame within which stained features can be located.

“…Often, we are interested in knowing how the acousto-optic interaction process affects the amplitude distribution among the different diffracted beams. We shall adopt the Korpel-Poon multiple plane-wave theory to understand this aspect, which is summarized as follows [28,30] . In Fig.…”

Optical image processing using acousto-optic modulators as programmable volume holograms: a review [Invited]

Bragg processing using a volume hologram offers an alternative in optical image processing in contrast to Fourier-plane processing. By placing a volume hologram near the object in an optical imaging setup, we achieve Bragg processing. In this review, we discuss various image processing methods achievable with acousto-optic modulators as dynamic and programmable volume holograms. In particular, we concentrate on the discussion of various differentiation operations leading to edge extraction capabilities.
