Abstract: A method may include scanning a surface of a composite workpiece with multiple electromagnetic pulses, each of the multiple electromagnetic pulses being associated with a respective location on the surface of the composite workpiece. The method may further include, for each respective location on the surface of the composite workpiece, receiving a response to one of the multiple electromagnetic pulses at a multi-mode fiber, the response including multiple wavelength components, time shifting the multiple wavelength components with respect to each other by passing the response through the multi-mode fiber to produce a wavelength-binned pulse, sampling the wavelength-binned pulse at time intervals corresponding to the multiple wavelength components to determine a set of wavelength intensity levels corresponding to the multiple wavelength components, and identifying a type or condition of material at the respective location on the surface of the composite workpiece based on the set of wavelength intensity levels.

Abstract: Provided herein are devices, systems, and methods for characterizing a biological sample in vivo or ex vivo in real-time using time-resolved spectroscopy. A light source generates a light pulse or continuous light wave and excites the biological sample, inducing a responsive fluorescent signal. A demultiplexer splits the signal into spectral bands and a time delay is applied to the spectral bands so as to capture data with a detector from multiple spectral bands from a single excitation pulse. The biological sample is characterized by analyzing the fluorescence intensity magnitude and/or decay of the spectral bands. The sample may comprise one or more exogenous or endogenous fluorophore. The device may be a two-piece probe with a detachable, disposable distal end. The systems may combine fluorescence spectroscopy with other optical spectroscopy or imaging modalities. The light pulse may be focused at a single focal point or scanned or patterned across an area.

Abstract: A spectral imaging device (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follow a beam path (16B) from the sample (10) to the image sensor (28). The refractive, optical element (24A) is spaced apart a separation distance (42) from the sample (10) along the beam path (16B). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), controls the mover assembly (29) (24C) to modulate the separation distance (42), and controls the image sensor (28) to capture the data.
