Abstract
A blood coagulation detection device includes a micro channel unit, an optical signal unit, an opto-electronic conversion circuit, an amplifier circuit, and a filter circuit. The micro channel unit has a sample detection area. The optical signal unit transmits a reference light to the micro channel unit so as to form a message light. The opto-electronic conversion circuit receives the message light and converts the message light into an electrical signal. The amplifier circuit is electrically connected to the opto-electronic conversion circuit for amplifying the electrical signal. The filter circuit is electrically connected to the amplifier circuit for filtering the amplified electrical signal.
