abstract

We present an imaging technique that acquires one-dimensional cross-section through a sample by imposing a chirped spatial frequency amplitude modulation on the probing beam. The spatial distribution of the sample is directly mapped to modulation frequency components of the spatially-integrated temporal signal from a singleelement detector. The electronic time-domain signals are the auto-correlation of the spatial frequency distribution of an image. The method is demonstrated by imaging both absorptive and florescent objects.
