Abstract
We present a spectrally encoded photoacoustic microscope based on a digital mirror device (DMD). It enables fast spatially resolved spectral measurements of optical absorption. The imaging system can quickly tune the laser illumination spectrum at the laser pulse repetition rate of 2 kHz. To demonstrate multi-wavelength absorption measurements, we imaged optically absorbing solution phantom. Compared with spectral scanning, spectral encoding recovers chromophore absorption spectra with improved accuracy by enhancing photoacoustic amplitude signal-to-noise ratio.
