An apparatus and method for ultrafast real-time optical imaging that can be used for imaging dynamic events such as microfluidics or laser surgery is provided. The apparatus and methods encode spatial information from a sample into a back reflection of a two-dimensional spectral brush that is generated with a two-dimensional disperser and a light source that is mapped in to the time domain with a temporal disperser. The temporal waveform is preferably captured by an optical detector, converted to an electrical signal that is digitized and processed to provide two dimensional and three dimensional images. The produced signals can be optically or electronically amplified. Detection may be improved with correlation matching against a database in the time domain or the spatial domain. Embodiments for endoscopy, microscopy and simultaneous imaging and laser ablation with a single fiber are illustrated.

Spectroscopic measurements are described based on light-molecule interaction in response to a resonant rate optical pulse train so that a Raman spectrum is reflected containing at least two types of vibrational mode information (e. g. , vibrational frequency, and vibrational phase relaxation) on the molecules comprising the object. A pump optical pulse train generation means is configured for generating an optical pulse train having an arbitrary repetition rate which is directed through irradiation means to the sample object. Light from the sample object is collected and vibrational coherence is detected for the sample object. The sample is tested across a plurality of different repetition frequencies. The detected information can be compared with data from other known samples from within a database when analyzing the information collected.

A barcode reading apparatus and method in which the spectrum of a probe light is first Fourier-transformed into space, directed upon a barcode, and then Fourier-transformed converting the spectrally encoded barcode pattern to a time domain waveform. In one implementation, the Fourier transformation from the spectrum domain into a spatial domain is performed by a dispersive element, while the Fourier transformation from the spectrally encoded barcode pattern to a time domain waveform is performed by group-velocity dispersion (GVD). The temporally encoded barcode pattern is detected by a photodetector, digitized by a digitizer, and analyzed by a digital signal processor. The invention is applicable to a number of fields which involve the reading of one- and two-dimensional barcodes, displacement sensing, surface measurements, measurement of width and gap, flow cytometry, reading of optical media, presense or absence detection, and other related fields.
