Research:
Professor Krishnaswamy's research interests are in optical and ultrasonic methods of nondestructive characterization of materials and structures. His past work has involved the development of a variety of optical techniques such as the method of bifocal caustics, the coherent gradient sensor, a polariscope/shearing interferometer, dynamic two-beam speckle interferometers, and noise-insensitive electronic speckle and dynamic holographic interferometric systems for optical metrology. He and his associates are currently working on:
(i) photo-acoustic
(laser ultrasonic) characterization of thin films and coatings;
(ii) phased-array laser ultrasonic imaging systems based on multiplexed
wave-mixing in photorefractive crystals;
(iii) scanning laser ultrasonic source techniques for nondestructive detection
of flaws in structures; and
(iv) fiber-optic sensors for smart structures
