The article describes design solutions and test results of a mobile device for the measurement of threshold perception frequency of the flickering source of visible light. The device consists of an optical component, a programmable module and a control module. The measurement can be performed on the light source of any color in conjunction with a colored backlight. The authors of the research work developed and tested a unique solution that integrates a subjective measurement of the flicker frequency f_f and the blending frequency f_m fusing in the flicker fusion test (FFT) with the registration of pupil vibrations that gives information about the level of activation of the autonomic nervous system (ANS). The ANS activation level is estimated in the test called the pupillographic sleepiness test (PST). It is an objective source of data on the level of fatigue, reduced concentration or sleepiness of a subject. The authors focused on the description of the measurement section related to the measurement of pupillary unrest index (PUI) and FFT parameters. The construction of the device allows for its use both in laboratory tests, as well as in terms of everyday human functioning.
