Infrared imaging microscope using tunable laser radiation

摘要

An imaging microscope (12) for generating an image of a sample (10) comprises a beam source (14) that emits a temporally coherent illumination beam (20), the illumination beam (20) including a plurality of rays that are directed at the sample (10); an image sensor (18) that converts an optical image into an array of electronic signals; and an imaging lens assembly (16) that receives rays from the beam source (14) that are transmitted through the sample (10) and forms an image on the image sensor (18). The imaging lens assembly (16) can further receive rays from the beam source (14) that are reflected off of the sample (10) and form a second image on the image sensor (18). The imaging lens assembly (16) receives the rays from the sample (10) and forms the image on the image sensor (18) without splitting and recombining the rays.

1. An imaging microscope for generating a two-dimensional image of a sample, the imaging microscope comprising:
a beam source that emits a temporally coherent illumination beam, the illumination beam including a plurality of rays; an illumination lens assembly that directs the illumination beam at the sample without splitting and recombining the illumination beam, the illumination lens assembly adjusting the illumination beam so that the illumination beam illuminates a two-dimensional illuminated area on the sample all at once; an image sensor that converts an optical image into an array of electronic signals, the image sensor including a two-dimensional array of sensors that are used to construct a two-dimensional image; and an imaging lens assembly that receives rays from the beam source that are transmitted through the sample and forms an image on the image sensor without splitting and recombining the received rays.
