Image acquisition device and image acquisition method
In an image acquisition device, when capturing an optical image of a sample S through lane scanning, the number of tile images T included in a tile image row R acquired in one lane is counted, and a determination is made as to whether or not the number of images reaches a planned acquisition count that is set in advance. In a case where it is determined that the number of images does not reach the planned acquisition count, lane scanning with respect to the lane is re-executed. Accordingly, even when a loss of the tile images T occurs due to an environment load, the tile images T are complemented by re-execution of the lane scanning, and thus it is possible to prevent the loss of the tile images T in an observation image.

Microscopy method and microscope for producing an image of an object
A microscopy method is for producing an electronic image of an object, wherein the object is imaged with an adjustable optical imaging scale on an image detector. The method includes: selecting a parameter for the electronic image, wherein the parameter can be influenced by the optical imaging scale and differs from the image field dimensions, and setting a setpoint value range for the parameter, setting a total imaging scale for the electronic image, wherein adjusting or controlling the parameter of the electronic image is implemented such that, at the same time, the parameter of the electronic image lies in the specified setpoint value range with a tolerance and the set total imaging scale is obtained, wherein the optical imaging scale forms a basis for a manipulated variable of the adjustment or closed-loop control and a digital image magnification is carried out on the basis of the set total imaging scale.

Multi-modal fluorescence imaging flow cytometry system
In one aspect, the present teachings provide a system for performing cytometry that can be operated in three operational modes. In one operational mode, a fluorescence image of a sample is obtained by exciting one or more fluorophore(s) present in the sample by an excitation beam formed as a superposition of a top-hat-shaped beam with a plurality of beams that are radiofrequency shifted relative to one another. In another operational mode, a sample can be illuminated successively over a time interval by a laser beam at a plurality of excitation frequencies in a scanning fashion. The fluorescence emission from the sample can be detected and analyzed, e.g., to generate a fluorescence image of the sample. In yet another operational mode, the system can be operated to illuminate a plurality of locations of a sample concurrently by a single excitation frequency, which can be generated, e.g., by shifting the central frequency of a laser beam by a radiofrequency. For example, a horizontal extent of the sample can be illuminated by a laser beam at a single excitation frequency. The detected fluorescence radiation can be used to analyze the fluorescence content of the sample, e.g., a cell/particle.

Systems and methods for optogenetic imaging
Provided herein are systems and methods for simultaneous imaging and stimulation using a microscope system. The microscope system can have a relatively small size compared to an average microscope system. The microscope can comprise in part an imaging light source and a stimulation light source. Light from the imaging light source and the stimulation light source can be spectrally separated to reduce cross talk between the stimulation light and the imaging light.
