This work proposed the Non-contact Stiffness Imager that could provide us with the pattern of Stiffness distribution of environment. While there were four combinations between the force applying method and the way for capturing the displacement, we picked up the combination in which the force was given to the environment at a local point and the idea by utilizing the experiment system composed of an air supply system and a line laser sensor. We applied the idea to an endoscope camera, so that we could obtain the pseudo-stiffness pattern as well as the visual pattern. We also showed a couple of experimental results exhibiting the pattern.
