摘要： A system for detecting pressure, acoustic or ultrasound waves within an entity having a surface including the steps of attaching a signal converting material to the surface. The waves are generated by direct ejection from the surface, generation via energy deposition on the surface, generated spontaneously or, generated by directing light energy to the light absorbing target. The absorbing target subsequently generates acoustic pressure waves. The acoustic waves propagate to the surface of the entity and the signal converting material, wherein the acoustic pressure waves create vibrations in the signal converting material; and detecting the waves in the signal converting material with an optical detection system. Information about the absorbing target is obtained by the absorbing target reflecting the waves. The signal converting material can be a gel-like material containing optical elements, a multi-layer patch, or other material.

摘要： A technique for bonding two dissimilar materials includes positioning a second material over a first material at an oblique angle and applying a tamping layer over the second martial. A laser beam is directed at the second material that generates a plasma at the location of impact on the second material. The plasma generates pressure that accelerates a portion of the second material to a very high velocity and towards the first material. The second material impacts the first material causing bonding of the two materials.

摘要： An apparatus for use with a high velocity laser deposition (HVLAD) process for depositing a coating on a non-planar surface of a structure. The apparatus may make use of a housing articulatable about at least two non-parallel axes so as to be able to follow a contour of the non-planar surface of the structure. A film may be carried on the housing which has a first surface facing away from the structure and a second surface facing toward the structure. A tamping medium may be configured to cover the first surface of the film. A laser source may be used to direct a laser beam at the first surface of the film at an oblique angle to the first surface of the film, which causes removal of a portion of the film and depositing of the removed portion of the film on the surface of the structure.
