    摘要: A light guide (50) includes a light-guide member (100) including an incidence portion (101) through which image light emitted from an image display element (10) enters the light-guide member (100); an exit portion (104) through which the image light exits the light-guide member (100) to an outside of the light-guide member (100); a retroreflection portion (106) to reverse a direction of travel of the image light guided through the light-guide member (100); and an extraction portion (103) to guide the image light reversed by the retroreflection portion (106) to the exit portion (104). The retroreflection portion (106) has a plurality of surfaces.

    摘要: A texture evaluation apparatus (100) includes a projector (1, 2), an imager (4), and an evaluator (5). The projector (1, 2) is configured to project a two-dimensional pattern (6) having an edge element onto an object (O). The imager (4) is configured to capture an image of a surface of the object (O). The evaluator (5) is configured to calculate an amount of shape change of a virtual image of the two-dimensional pattern (6) in the image, and evaluate texture of the object (O) based on the amount of shape change and sensory evaluation information obtained in advance.
