An imaging apparatus may be used for histological and/or molecular imaging of a tissue sample. An imaging apparatus may include one or more light sources that generate one or more excitation beams directed toward an excitation location being focused on the sample to generate signals in the sample and one or more interrogation beams directed toward a detection location such that a portion of the one or more interrogation beams returning from the sample is indicative of at least some of the generated signals. An imaging apparatus may include a photodetector configured to detect radiative signals from the sample. An imaging apparatus may generate an image of the sample using only pressure (photoacoustic) signals, only temperature (photothermal) signals, and/or both photoacoustic and photothermal signals from the generated signals.

Photon absorption remote sensing system for histological assessment of tissues

A method for visualizing details in a sample including directing an excitation beam to an excitation location below a surface of the sample, to generate signals in the sample; directing an interrogation beam toward the excitation location of the sample; directing a signal enhancement beam to the sample, to raise a temperature of a portion of the sample by 5 Kelvin or less, compared to a temperature of the portion of the sample in absence of the signal enhancement beam; detecting a portion of the interrogation beam returning from the sample that is indicative of the generated signals.
