Abstract: One or more spectrally encoded endoscopy (SEE) devices, systems, methods and storage mediums for characterizing, examining and/or diagnosing, and/or measuring viscosity of, a sample or object using speckle detection are provided. Examples of such applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments. Preferably, the SEE devices, systems methods and storage mediums include or involve speckle intensity autocorrelation function(s). One or more embodiments involve a serial time-encoded 2D imaging system with speckle detection to reconstruct images, store reconstructed images of the sample or object, and/or measure viscosity of the sample or object.

Abstract: A DWS apparatus includes a coherent light source, a photodetector, a control unit which can measure an intensity autocorrelation function, a measuring unit which can measure a source-detector distance to obtain source-detector distance data, and a calibrating unit which adjusts the intensity autocorrelation function by using the source-detector distance data. The calibrating unit calibrates the intensity autocorrelation function by adjusting the time constant of the autocorrelation function based on a comparison of the source-detector distance to the time constant of the intensity autocorrelation function.
