Title: Innovations of Luis A. Nieva
Introduction
Luis A. Nieva is a notable inventor based in Lima, Peru, recognized for his contributions to the field of microscopy and acousto-photonic detection. He holds two patents that showcase his innovative approach to enhancing detection methods in optically turbid media.
Latest Patents
One of his latest patents is titled "Opto-acoustic signal detection with coherent confocal microscopy." This invention involves a microscopy apparatus that utilizes a heating source to generate motion in a localized region of a target, such as human tissue. The apparatus includes a measuring source that focuses a light beam on the target, a coherent confocal microscopy assembly, and a detection assembly that identifies a Doppler shift in the reflected signal. The scanning assembly plays a crucial role in building an image of the target.
Another significant patent by Nieva is "Enhanced detection of acousto-photonic emissions in optically turbid media using a photo-refractive crystal-based detection system." This system improves detection sensitivity for acousto-photonic emissions in turbid media. It comprises an ultrasonic transducer, a laser, and a photo-detector that processes the detected signals for analysis. The ultrasonic transducer generates waves that propagate through the turbid medium, while the laser creates a coherent light beam that is phase modulated by the ultrasound.
