Although modern optical microscopy allows the achievement of sub-diffraction resolution, most of the current techniques rely on a fluorescence contrast mechanism.

The infrared absorption/saturation microscopy method is designed to overcome these issues [1, 2], having InfraRed Nanoscopy (IRN) as an instrumental perspective. The main idea behind IRN is an absorption/saturation effect similar to conventional pump-probe in which the first pump beam modifies the carrier density inside the sample, followed by intensity changes in the transmitted probe beam.

Abstract

Although modern optical microscopy allows the achievement of sub-diffraction resolution, most of the current techniques rely on a fluorescence contrast mechanism. Moreover, deep tissue imaging remains a challenging task especially for thick and highly scattering biological objects. The infrared absorption/saturation microscopy method is designed to overcome these issues [1, 2], having InfraRed Nanoscopy (IRN) as an instrumental perspective. The main idea behind IRN is an absorption/saturation effect similar to conventional pump-probe in which the first pump beam modifies the carrier density inside the sample, followed by intensity changes in the transmitted probe beam.
