A method for the optical measurement of a variation in temperature of an object (O) includes: an emission step (S1) consisting of emitting, in the direction of the object (O), a first incident electromagnetic wave (W1_inc) of the terahertz type, and a measurement step (S2) including the measurement (S2_3), by a sensor sensitive to terahertz radiation (20), of a variation in amplitude of the electromagnetic radiation of a second electromagnetic wave (W2_ref, W2_tra) in order to determine the variation in temperature of the object (O). |
