| Sumario: | 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-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). |
