1. A method of detecting particles, said method comprising: generating a reaction to a plurality of particles using a converter material, wherein said converter material is operable to interact with said plurality of particles; converting a response to said reaction to a readable electrical signal using a sensor, wherein said sensor comprises an array of discrete pixel sensors each with a respective (x,y) coordinate within said array; processing said readable electrical signal from said sensor to generate information regarding each pixel on said array; transmitting said information to a processing unit; and analyzing said information using said processing unit to determine instances of impingement of said plurality of particles on said array.
