Abstract：
 The invention relates to a sensing method of a protein array chip and its detecting system in the field of biology technique. The method comprises the following steps: letting the light reflected by the protein array chip to get through a one-dimensional magnifying lens array and inject into a time are phase modulator, changing the voltage to let the ejected s light and p light to get through the polarizing prism to generate intervention, changing the image into the electric signal by CCD after imaging lens and inputting it into the computer; when changing a phase of p light, it collects an image; using the collected five images as a circulation to obtain the time phase changing information aroused by the reaction of each unit of the array chip.
