Abstract
The present invention relates to a detection mechanism for polymerase chain reaction and a polymerase chain reaction device, wherein the detection mechanism comprises at least one excitation module group, each of the excitation module groups comprising two excitation modules for providing excitation light with two wavelengths; an excitation optical fiber, connected to the excitation modules, the excitation optical fiber transmitting the excitation light to at least one reaction tube, each of the reaction tubes receiving excitation light with two wavelengths; a receiving optical fiber, for collecting and transmitting a fluorescent signal from the reaction tube; at least one receiving module group, connected to the receiving optical fiber, each of the receiving module groups comprising two receiving modules, to respectively receive the fluorescent signal of two wavelengths from the same said reaction tube, and convert the fluorescent signal into an electrical signal for output; the detection mechanism is configured to detect the reaction tube in a time division manner, and multiplex the receiving module group to obtain an output result.
