Introduction

Lawrence R. Senesac is a notable inventor based in Knoxville, TN, with a significant contribution to the field of photo detection technology. He holds a total of six patents, showcasing his expertise and innovative spirit in enhancing the sensitivity and functionality of photo detecting devices.

Latest Patents

One of his latest patents is titled "Acoustic enhancement for photo detecting devices." This invention provides improvements to photo detecting devices and methods for enhancing their sensitivity. The device generates an electronic signal in response to a received light pulse. An electro-mechanical acoustic resonator, which is electrically coupled to the photo detecting device, dampens the electronic signal and increases the signal-to-noise ratio (SNR) of the electronic signal. This advancement results in increased photo detector standoff distances and sensitivities.

Another significant patent is "Photoacoustic microcantilevers." This system generates a photoacoustic spectrum in either an open or closed environment with reduced noise. A source focuses a beam on a target substance that is disposed on a base. The base supports a cantilever that measures the acoustic waves generated as light is absorbed by the target substance. By focusing a chopped or pulsed light beam on the target substance, a range of optical absorbance can be measured as the wavelength of light changes. An identifying spectrum of the target may be detected by monitoring the vibration intensity variation of the cantilever as a function of the illuminating wavelength or color.
