Embodiments of this invention relate generally to detection systems and a method for chemical substance detection using UV fluorescence, specular reflectance, and artificial intelligence. In one example, a handheld detection system comprises single or multiple excitation light sources at discrete wavelengths operating in an ultraviolet portion of an electromagnetic spectrum. The single or multiple excitation light sources are operated intermittently, either all in concert or individually, at a frequency of about 100 Hz to 1000 Hz. Multiple detectors are configured as channels to operate at discrete wavelengths to detect a multiplicity of emissions produced by the excitation energy. A multi-channel electronic or software-implemented detector is synchronized in both phase and frequency with the excitation light sources so that a signal of interest is detected in the multiplicity of emissions.

A microorganism detection system is provided for being disposed on a device to be detected which is closed, including a flow channel and a detection module. A fluid to be detected in the device to be detected flows in the flow channel. The detection module is disposed within the flow channel, including two slides, a microscopic module and at least one telescopic mechanism, each of the at least one telescopic mechanism is connected to one of the two slides and the flow channel. When the two slides approach each other, the fluid to be detected in a gap between the two slides is observable through the microscopic module.
