Abstract
Methods, devices, and systems for imaging tissue and other samples or samples using infrared (IR) transmissions from coherent transmission sources, such as a wide range, tunable, quantum cascade laser (QCL) designed for the rapid collection of infrared microscopic data for medical diagnostics across a wide range of discrete spectral increments. The infrared transmissions are transmitted through, reflected from, and/or transreflected through a sample, and then magnified and/or focused prior to being detected by a detector. After detection, the sample related image data is used to assess the sample. Such methods, devices, and systems may be used to detect abnormalities in tissue, for example, before such abnormalities can be diagnosed using art cytopathological methods. The methods, devices and systems may also optionally include a visible light detection subsystem and/or a motion control subsystem to assist in control and processing of imaging.
