Non-contact touch delay detection system

A non-contact touch delay detection system disclosed by the present invention comprises a support sliding plate arranged on one side of a device to be detected, the device to be detected comprises a touch frame and a display device, a plurality of photoelectric emission ends are installed on one side frame of the touch frame side by side, and a plurality of photoelectric receiving ends are installed on the other side frame of the touch frame side by side. A plurality of touch simulation assemblies used for simulating finger sliding and clicking are arranged between the touch frame and the supporting sliding plate, the photoelectric transmitting end and the photoelectric receiving end correspond to the touch simulation assemblies, a light detection module and a measurement and control host are arranged above the supporting sliding plate, and a display screen is installed on the upper portion of the measurement and control host. According to the technical scheme, click delays of different frequencies can be tes
