Patent ID: 7859670

Claim:
A fluorescence detection system for detecting fluorescence in a microfluidic chip having at least a microchamber, comprising: a chip mount upon which the microfluidic chip is placed; an optical device which emits light on the microfluidic chip and detecting fluorescence which is generated from a fluorescent material existing in the microfluidic chip; a carriage which transports the chip mount or the optical device at a predetermined speed, so that the optical device emits the light on the microfluidic chip while scanning the microfluidic chip; a measuring unit which measures an optical signal detected by the optical device and converts the optical signal into a digital signal; and a calculator which calculates the amount of the fluorescent material in the microfluidic chip based on a measured value, wherein the calculator acquires a position of an outer circumference of the microfluidic chip from the optical signal detected by the optical device, and calculates a position of the microchamber based on the position of the outer circumference and distance between the outer circumference and the microchamber, and wherein the measuring unit calculates a portion of the optical signal which is generated from the microchamber of the microfluidic chip based on the acquired position of the microchamber, and sends a calculated value of the optical signal portion to the calculator.
