Latest Patents

Among Venkataraman Swaminathan's latest innovations are two notable patents:

1. **Apparatus and method for improving detection precision in laser vibrometric studies**

This innovative laser vibrometer design targets the vibratory characteristics of moving objects, achieving a superior signal-to-noise ratio through the implementation of multiple channels. The system divides the laser into various channels, further splitting each into a reference beam and a probe beam. The probe beam is aimed at the object while the backscattered reflections are analyzed against the reference beam to ascertain the object's vibratory traits. The signals gathered from the multiple channels are distinct, sequential, and non-overlapping.

2. **Enhanced sensitivity vibrometer**

This enhanced sensitivity laser vibrometer offers increased output signal strength and improved surface vibration detection. It incorporates a reflective mirror assembly that bounces the sensing laser beam against an acoustic pressure-sensing diaphragm, amplifying the detected acoustic incident pressure wave. Experimental demonstrations have revealed that the enhancement in signal strength is a function of the number of bounces squared, enabling the detection of surface vibrations with displacements smaller than 4 picometers.
