FIELD: physics.
SUBSTANCE: invention relates to method for creation of spatial body (3) in process of stereolithography. Said method enables light-sensitive material (9) to be cured by radiation. Measurement radiation is introduced into support layer (80) and, as a result of internal reflection, it remains mainly within support layer (80). Measuring radiation is detected with spatial resolution and time resolution by means of sensor (5).
EFFECT: technical result is high accuracy of monitoring the process of creating an object.
