Abstract: The purpose of the present invention is to provide an apparatus and a method for measuring a deformation rate which is generated during a mechanical test using a contactless optical method. Specifically, provided in the present invention are an apparatus and a method for effectively measuring the deformation rate of a specimen using a single system from room temperature to 3,000 deg. C by solving a problem that an accurate image acquisition is difficult due to self radiation and heat emission of a specimen in a high temperature test. The contactless method for measuring a deformation rate at high temperatures comprises a specimen mounting unit (100) which increases the temperature of a specimen (1) by mounting the specimen (1) whose deformation rate is to be measured, and applies stress to the specimen (1) to be deformed; a light source unit (200) which radiates light to the specimen (1) mounted on the specimen mounting unit (100); an image photographing unit (300) which photographs the image of the specimen (1) using light reflected from the specimen (1) after being radiated from the light source unit (200); and a deformation rate measuring unit (400) which calculates the deformation rate of the specimen by analyzing the image data collected by the image photographing unit (300).
