红外光热外差成像(IR-PHI)是一种超灵敏技术,能够通过吸收中红外光来实现样品的超分辨率化学和形态表征。虽然早期的IR-PHI迭代涉及逐点栅格扫描,但在这里,我们引入了一种宽场模式IR-PHI,它利用与超高速互补金属氧化物半导体相机同步的ns时间级红外泵浦脉冲来并行数据采集。图像采集时间减少了300倍,从20分钟下降到4秒。
Infrared photothermal heterodyne imaging (IR-PHI) is an ultrasensitive technique capable of achieving super-resolution chemical and morphological characterization of specimens via absorption of mid-infrared light. While early iterations of IR-PHI have involved point-by-point raster-scanning, here, we introduce a widefield modality to IR-PHI that utilizes ns-timescale infrared pump pulses synchronized to an ultrafast complementary metal-oxide-semiconductor camera to parallelize data acquisition. A 300-fold decrease in image acquisition time is realized, falling from 20 minutes to four seconds.
