Abstract
An orientation evaluation device includes: a diode laser configured to periodically irradiate a sample with light to heat the sample, the sample being carbon fiber reinforced plastics; an infrared thermography configured to detect delay in response to a change in a temperature distribution of an area of the sample, the area including a spot heated by the diode laser; and a computer configured to output information on orientation of the sample based on the delay in the response detected by the infrared thermography. The orientation evaluation device enables a non-contact and quick evaluation of the orientation of the sample.
