5-3 Ultrasonic Holography

Tailoring ultrasonic beams with optoacoustic holography

A combination of laser-induced ultrasound generation and ultrasonic holography for spatial control of the generated ultrasonic pulse is presented. Ultrasound is produced by absorption of laser pulses at an absorbing layer in a water tank via the optoacoustic effect. In order to produce a defined ultrasonic frequency in the MHz range, the laser pulses are harmonically time-modulated using an aco...

On stringy AdS 5 × S 5 and higher spin holography

We derive the spectrum of Kaluza-Klein descendants of string excitations on AdS5 × S5. String states are organized in long multiplets of the AdS supergroup SU(2, 2|4,R) with a rich pattern of shortenings at the higher spin enhancement point λ = 0. The string states holographically dual to the higher spin currents of SYM theory in the strict zero coupling limit are identified together with the c...

Holography , Stereoscopy and Blender 3 D

This paper shortly describes Blender 3D modification and its use for the design of mechanical parts. The 3D modification of the Blender modeling system and experiments made brought interesting results especially from the human-computer interaction field. The modification relies on the stereoscopy based devices which are currently available at the market. However, the stereoscopy has some drawba...
