Abstract
A texture image acquiring device, a display device and a collimator are disclosed. The texture image acquiring device includes a collimator and an image sensor. The collimator includes a lens array, a first diaphragm layer, and a second diaphragm layer. The lens array allows light rays to be converged and incident on the first diaphragm layer. The first diaphragm layer allows light rays incident on the first diaphragm layer to pass through and be incident on the second diaphragm layer, and restricts an angle of light rays capable of passing through the first diaphragm layer. The second diaphragm layer allows light rays incident on the second diaphragm layer to pass through, and restricts an angle of light rays capable of passing through the second diaphragm layer. The image sensor senses light rays incident on the image sensor for acquiring a texture image.
