Abstract

The various embodiments disclosed herein utilize multiple lasers that have different wavelengths and a single detection path. The lasers are mounted orthogonal to one another so that one laser will provide a forward angle light scatter (FALS) signal in the detection path, and one laser will provide a side scatter signal in the detection path (i.e., the single detection optics are approximately in-line with the FALS laser and approximately orthogonal to the side scatter laser). The single detector path spectrally separates the forward and side scatter signals prior to applying them to their respective detectors for measurement.
