ORIENTATION IDENTIFICATION DEVICE, ORIENTATION IDENTIFICATION METHOD, AND DISTRIBUTION IDENTIFICATION DEVICE

摘要

An orientation identification device according to the present invention is provided with: a diode laser that periodically emits light to a sample made of a carbon fiber reinforced resin to heat the sample; an infrared thermography that detects a delay in response of a change in a temperature distribution over an area including a portion of the sample which has been heated by the diode laser; and a computer that outputs information representing the orientation of the sample on the basis of the delay in the response detected by the infrared thermography, so that the orientation identification device, which is capable of quickly identifying the orientation of the sample in a non-contact manner, and so on are provided.
