Abstract: PURPOSE: An apparatus and a method for measuring three dimensional shape using color projection moire technique are provided, which can improve measurement speed by measuring phase information calculated by the grid pattern. CONSTITUTION: An apparatus for measuring three dimensional shape using color projection moire technique comprises a computer(14), a projector(10), and a color CCD camera(12). The computer generates three RGB patterns with different grid gaps using an internally stored program. The projector projects the RGB pattern to a measurement object(11). The color CCD camera obtains the RGB pattern projected to the measurement object as an image. The apparatus for measuring three dimensional shape measures the phase information measured through the CCD camera.

Abstract: A thermal expansion coefficient measuring interferometer and a method thereof are provided to measure thermal expansion coefficient more accurately by measuring the minute length change of a measurement object according to the temperature change. A thermal expansion coefficient measuring interferometer comprises a polarization beam splitter(220) and a plurality of corner cube prisms(232,234,236). The polarization beam splitter reflects and transmits a first beam and a second beam according to the polarization component so that the first beam is split into a third beam and a fourth beam and the second beam into a fifth beam and a sixth beam. The corner cube prism changes the beam path of the incident beam if at least one of the third beam and the sixth beam enters from the polarization beam splitter.

Abstract: An interferometer for measuring thermal expansion coefficient can calculate the amount of length change of a measurement object more accurately without an error due to the deformation of the glass plate according to temperature. An interferometer for measuring thermal expansion coefficient includes a measurement target system(250), an optical system(210), and a vacuum chamber(200). The measurement target system comprises a measurement object(254) and a reference plate(255) on which the measurement object is loaded. The optical system splits incident light, modulates the frequency of the split light, and projects the modulated light to the measurement object and the reference plate respectively. The optical system also couples the respective light reflected from the measurement object and the reference plate, and detects the beat signal generated due to the interference generated in the optical coupling. The vacuum chamber maintains the vacuum condition with the measurement target system and optical system installed inside.
