Particle measurement apparatus and method
First Claim
1. A particle measurement apparatus comprising:
- a particle signal detecting section for detecting a particle signal with respect to a plurality of particles, the particle signal representing characteristics of each particle;
a false signal generating section for generating a false signal corresponding to the particle signal;
a selecting section for selecting the particle signal or the false signal, a non-linear amplifier;
a first calculating section for receiving the signal selected by the selecting section through the non-linear amplifier to calculate a characteristic parameter;
a second calculating section for receiving the signal selected by the selection section not through the non-linear amplifier to calculate the characteristic parameter;
a comparison section for comparing the characteristic parameters calculated by the first and second calculating sections respectively when the selecting section selects the false signal;
a storage section for storing a comparison result of the comparison section; and
a compensating section for compensating the characteristic parameter calculated by the first calculating section on the basis of the comparison result when the selection section selects the particle signal.

Abstract
A particle measurement apparatus includes: a particle signal detector for detecting a particle signal; a false signal generator for generating a false signal corresponding to the particle signal; a selector for selecting the particle signal or the false signal, a non-linear amplifier; a first calculator for receiving the signal selected by the selector through the non-linear amplifier to calculate a characteristic parameter; a second calculator for receiving the signal selected by the selector not through the non-linear amplifier to calculate the characteristic parameter; a comparator for including the characteristic parameters calculated by the first and second calculators respectively when the selector selects the false signal; a memory for storing a comparison result of the comparator; and a compensator for compensating the characteristic parameter calculated by the first calculator on the basis of the comparison result when the selector selects the particle signal.
