| 摘要 |
The invention concerns a method and system for determining particle size information of particles contained in a sample (5), the method comprising illuminating the particles with at least three light sources (3a, 3b, 3c) placed on different locations, detecting light reflected from the particles using a detector (1 ) capable of spatial resolution, and processing the output of the detector (1 ) so as to determine the particle size information. According to the invention, the particles are illuminated simultaneously with the at least three light sources (3a, 3b, 3c) each operating at a different wavelength channel, and the wavelength channels are simultaneously detected at the detector (1 ). The invention reduces the need for sample (5) preparation, among other benefits. |
