ABSTRACT:
A technique for analyzing analytes in a chemical array having a plurality of pixels is provided. The apparatus of the technique contains a light source for irradiating a light beam at the pixels individually, a controller for controlling the relative position of the light source to the array, and a detector for detecting fluorescence resulting from irradiation. The controller controls the light beam generated by the light source to irradiate a first number of pixels sequentially in the array and repeating one or more times the sequential irradiation before irradiating a second number of pixels, the pixels of which are different from those of the first number of pixels. The first number of pixels includes more than one pixel but less than the total number of pixels in the array.
