Claim of US Patent No. 10,690,593

1. A sample analyzer, comprising:a detector detecting scattered light from a sample that is irradiated by an inspection light;
a processing device configured to:
obtain a reference function comprising an autocorrelation function of a reference signal as a function of a delay time;
calculate, with an autocorrelation function calculation part, autocorrelation functions of detection signals as a function of a delay time, the detection signals obtained by irradiating a sample with inspection light, to obtain a plurality of comparison target functions;
determine, with an autocorrelation function determination part, whether or not a displacement amount of each of the plurality of comparison target functions from the reference function is within a predetermined range over a predetermined delay time range;
analyze, with a sample analysis part, the sample using ones of the plurality of comparison target functions of the sample that have displacement amounts determined by the autocorrelation function determination part to be within the predetermined range over a predetermined time range; and
discard ones of the plurality of comparison target functions having displacement amounts determined by the autocorrelation function determination part to be outside of the predetermined range over the predetermined delay time range.
