Portable spectrometer scattered light and process for determining the temporal autocorrelation function of the average

摘要

"Portable spectrometer scattered light and process for determining the temporal autocorrelation function of the average" this invention deals with a portable spectrometer scattered light (andPel) that uses the correlation of photons to measure and characterize dynamic light scattering in colloidal emulsions.Also deals with a process for determining the average time autocorrelation function.The device proposed in this invention has a mechanical optical system with a special configuration that includes at least a source of coherent light, lens, beam splitter,Optical element which reflects and transmits the beam from the light source.The element with the property of polarization and other elements that provide superior characteristics such as: small size; portable; easy handling; robust; performs measurements of dynamic difusiVA in the shortest time; can be used to open in lighted environment, without the need to block the external ambient light on the sample and in different places; and good tolerance to vibration.In addition to enable the configuration of the optical mechanical system in all orientations in space.The EPEL can be used in laboratories and also for determinations of diffusive dynamics "in situ", including immuno tests
