<p>PURPOSE: A TOF(Time of Flight) camera is provided to change a modulation frequency for the light of a subject through an electro-optic modulator and a micro controller to exclude the limit in the distance from a subject. CONSTITUTION: An electro-optic modulator(1) modulates the light of a light source(6) in a predetermined frequency. A sensor array(7) converts the light into an electric signal, and the light is reflected from a subject. A micro controller(2) converts a frequency of AC(Alternating Current) voltage through the control of a power supply unit. By comparing the light of the light source with the phase of the sensed light, the microcontroller calculates the distance to the subject.</p> |
