Abstract: The present disclosure relates in general to Diffuse Correlation Spectroscopy system for obtaining an autocorrelation function, and more particular, to a correlator and method for controlling a sampling time period and data length used for calculating an autocorrelation function. The correlator may include, a sampling gate circuit which is open during a variable time period and provides a data sample, a correlation circuit which calculates a correlation function from the data sample provided from the sampling gate circuit, and a parameter determining circuit which determines a sampling time period to be used by the sampling gate circuit based on the correlation function.

Abstract: There is provided a new apparatus, system, and method of use for laser speckle imaging that allows for omni-directional viewing. The omni-directional viewing can include a reflector and switches configured for switching the illumination on the lumenal tissue such that the light reflected from the lumenal tissue at any given time is reflected from one or more substantially non-overlapping sections of a lumenal tissue. This apparatus may be particularly useful for tissue analysis such as analysis of vulnerable plaque.
