TL;DR: An accurate method for studying the functional dynamics of the beating embryonic zebrafish heart by combining a newly developed confocal slit‐scanning microscope, novel strategies for collecting and synchronizing cyclic image sequences, and data analysis and reduction protocols for the systematic extraction of quantitative information to describe phenotype and function are reported.

TL;DR: The concept of a fast fluorescence line scanner providing image acquisition speeds in excess of 100 frames per second at 512 x 512 pixels is introduced, and the system preserves the capability for optical sectioning of confocal systems, it allows to observe processes with three-dimensional resolution.

TL;DR: In this article, an arrangement comprises an optical modulator for fast modulation which is provided in an interferometer arm of the inter-ferometer arrangement for heterodyne detection.

TL;DR: In this paper, an arrangement for the optical detection of light radiation which is excited and/or backscattered in a specimen in a microscope is presented, wherein the specimen illumination is focused in and or in the vicinity of a pupil plane of the beam path between the specimen plane and detection plane and apparatus is provided in this plane for spatially separating the illumination light from the detection light.

TL;DR: An optical assembly for the detection of light from a sample, using a microscope, comprises a system to separate the illuminating light from the detection light in and/or near the plane between the eye pupil and the sample.
