Abstract
Provided is a method for evaluating fluid flow characteristics of a lens-free complementary metal-oxide semiconductor (CMOS) optical sensor package module with a flow channel. The method includes: measuring a propagation profile and a flow velocity in an initial state flow of a fluid in the flow channel; calculating a first statistical parameter relating to flow characteristics of the fluid from the measured propagation profile and flow velocity; and comparing the calculated first statistical parameter with a preset reference value and evaluating quality of the flow channel according to the comparison result.
