Illumination system for optoacoustic imaging based on LEDs and EDU-CIAA

Optoacoustic imaging is a hybrid technique that benefits from both the versatile optical contrast and the high spatial resolution associated with the low propagation dispersion of ultrasonic waves. Usually, high energy lasers (> 10 mJ) are used as a light source which are expensive, non-porta...

Usually, high energy lasers (> 10 mJ) are used as a light source which are expensive, non-portable and have a low repetition rate (~20 Hz). In recent years, the use of light-emitting diodes (LEDs) as substitute has been studied because of they are less expensive, more reliable and compact, and they can provide thousands of pulses in a second for real-time imaging. This paper presents the implementation of an illumination system based on LEDs and the embedded system EDU-CIAA. The developed system is capable of emitting short light pulses (< 1 us) with great intensity and high frequency (> 1 kHz). La obtención de imágenes optoacústicas es una técnica híbrida que se beneficia tanto del rico y versátil contraste óptico como de la alta resolución espacial asociada a la baja dispersión de propagación de las ondas ultrasónicas. Usualmente, se utilizan láseres de elevada energía (> 10 mJ) como fuente de luz los cuales son caros, no portátiles y tienen una baja tasa de repetición (~20 Hz). En los últimos años se ha estado investigando el uso de diodos emisores de luz (LEDs) como sustituto ya que son menos costosos, más confiables y compactos, y pueden proporcionar miles de pulsos en un segundo para obtener imágenes en tiempo real. En esta trabajo se presenta la implementación de un sistema de iluminación basado en LEDs y en el sistema embebido EDU-CIAA que es capaz de emitir pulsos de luz de corta duración (< 1 us), con gran intensidad y elevada frecuencia (> 1 kHz). application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/107 10.37537/rev.elektron.4.2.107.2020 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/107/200 https://elektron.fi.uba.ar/elektron/article/view/107/214 Derechos de autor 2020 Emiliano Gasparovic Elektron Journal; Vol. 4 No. 2 (2020); 64-68 Revista Elektron; Vol. 4 Núm. 2 (2020); 64-68 Revista Elektron; v. 4 n. 2 (2020); 64-68 2525-0159 2525-0159 optoacústica LED sistema embebido Illumination system for optoacoustic imaging based on LEDs and EDU-CIAA Sistema de iluminación para obtención de imágenes optoacústicas basado en LEDs y EDU-CIAA info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=107_oai
