The output from a THz measurement of skin. The start point of the measurement, where stable contact with the imaging window was reached at the correct pressure, is marked by the orange dashed line. a) The pressure sensor binary output, b) the impulse function Peak-to-Peak (P), c) the impulse function at the start of the measurement both before and after the contact of the skin with the imaging window. The impulse functions are shifted horizontally for clarity and only one signal of the window before contact is displayed in red
