Abstract: There is provided an imaging technology using a speckle, which is capable of eliminating cross-talk. In the present technology, there is provided an imaging system including: a first light source that irradiates an imaging target with coherent light of a first wavelength band; a second light source that irradiates the imaging target with incoherent light of a second wavelength band; an image capturing unit that captures a speckle image and a non-speckle image, the speckle image being obtained from scattered light of the imaging target irradiated with the coherent light, the non-speckle image being obtained from reflected light of the imaging target irradiated with the incoherent light; and a cross-talk elimination unit that eliminates cross-talk that occurs between the captured speckle image and the captured non-speckle image.

Abstract: To provide an image analyzing technology capable of obtaining an image with less shading and with enough speckle contrast. An imaging apparatus includes: a light source that irradiates an imaging object with coherent light with a first irradiation condition and a second irradiation condition; a speckle imaging unit that captures a first speckle image obtained from scattered light of the imaging object irradiate at the first irradiation condition, and a second speckle image obtained from scattered light of the imaging object irradiate at the second irradiation condition; and an information processing unit that separates speckle images at boundaries of average luminance difference formed in the first speckle image and the second speckle image, connecting the separaged speckle images at the boundaries, and analyzes the combined speckle combined image.

Abstract: An electroencephalogram analysis apparatus includes an electroencephalogram acquisition part and a comparison part. The electroencephalogram acquisition part is configured to acquire a first electroencephalogram measured at a first region on a head of a test subject and a second electroencephalogram measured at a second region positioned behind the first region on the head of the test subject. The comparison part is configured to compare a power of the first electroencephalogram in a specific frequency band with a power of the second encephalogram in the specific frequency band.

Abstract: To provide a biological signal measuring equipment that can perform the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion. A biological signal measuring equipment used in the measurement of the biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with the occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends.
