Abstract
The matrix biochip sensing system of this invention uses a low-cost LED (light emit diode) matrix as the light source for the sensing system. The matrix biochip sensing system comprises an LED matrix light source, a biochip clamping member, an optical information filter module, an optical lens array, an optical sensor and a signal processing and control module. The light spots of the LED matrix is turned on in sequence, such that the fluorescent spots of the biochip that are respectively corresponding to the light spots of the laser diodes matrix may be actuated in the same sequence. Fluorescent spots so actuated are focused to a single optical sensor through an optical lens. At each sensing cycle of the optical sensor, only one fluorescent spot may be actuated. The output of the optical sensor in combination of the time axis may be processed by the signal processing and control module to obtain the genetic signals of the biochip.
