Control imaging methods in advanced ultrafast electron microscopy

摘要

An optical system includes a beam splitter disposed along an optical axis and a set of mirrors optically coupled to the beam splitter. The set of mirrors are oriented perpendicular to each other. The optical system also includes a turning mirror optically coupled to a second mirror of the set of mirrors and a detector optically coupled to the turning mirror.

1. A microscope system comprising:
a microscope column; an electron beam path disposed within the microscope column, wherein the electron beam path impinges on a specimen disposed in the microscope column; a laser beam path operable to support a laser beam and disposed both external to and within the microscope column, wherein the laser beam path impinges on the specimen; a beam splitter disposed along the laser beam path and operable to split the laser beam into a specimen path and a detection path; a set of mirrors disposed along the detection path and optically coupled to the beam splitter, wherein the set of mirrors are oriented perpendicular to each other; a turning mirror disposed along the detection path and optically coupled to a second mirror of the set of mirrors; and a detector optically coupled to the turning mirror.
