摘要:
A simulation method for imaging of an underwater object is performed by simulating the object with a test panel having several strips of different brightness, and irradiating the test panel with a pulsed laser beam having three primary colors. From the reflected beam pulses, contrast values of the test stripes are computed for reflected pulses of each color in relation to the turbidity and visibility distance. The method may be used in conjunction with an imaging apparatus having a laser generation device which produces three primary colors of three different wavelengths; a laser beam detection device to receive the reflected beam pulses of respective primary colors, to determine intensities of the reflected beam pulses of respective primary colors, and to output three primary color signals to an image monitoring device. The imaging system may also be arranged so that a laser irradiation device, a laser beam detection device and an image monitoring device are all placed underwater in a submersible vessel with appropriate provisions for hydrostatic pressure and unmanned operation.

The present invention aims to reduce a size and improve quality of an infrared sensor. An infrared sensor (203) according to the present invention includes a substrate (202) and an infrared detection element (201). A principal surface of the substrate (202) includes a convex shape. The infrared detection element (201) is formed over the principal surface including the convex shape of the substrate (202). Further, as for the infrared detection element (201), an entire light-receiving surface includes a planar shape. Then, it can be the small-sized infrared sensor (203) with improved quality.
摘要:
A mixed powder of AlH3 and MgH2 is ball-milled in a hydrogen atmosphere while applying force of 5 G through 30 G (in which G is gravitational acceleration), and the thus-obtained milled product is dehydrogenated to produce a hydrogen storage material. The hydrogen storage material comprises an amorphous phase containing an Al—Mg alloy as a mother phase, and a crystalline Al phase having a maximum length of 100 nm or less, the crystalline Al phase being distributed as a dispersed phase in the mother phase.
