Abstract
A tactile sensation presentation device includes a light source that emits a laser beam toward a test site that is a region of a skin surface of a biological object and a control device that generates a control signal that controls the light source and causes the light source to emit the laser beam in a modulated manner. The laser beam emitted from the light source in a manner modulated in accordance with the control signal from the control device whereby the test site is irradiated is absorbed at the test site and generates a pressure wave that is a thermoelastic wave by the photoacoustic phenomenon.
