MATANGO, Santiago  e  AVALOS, Eduardo. Design and Implementation of a Bifrequencial System Based on Low Power Lasers. Rev Politéc. (Quito) [online]. 2020, vol.45, n.2, pp.57-66. ISSN 2477-8990.

This paper describes the design and implementation of a bifrequencial system that can be used as an alternative for the treatment of diseases in the mouth by irradiating low power laser light. The system is a prototype, whose mechanical design is created in a free-use software and then printed on a 3D model which houses all the electronic and optical part, as for the electronic part it is mounted on several modules which meet different functions such as the battery charger, power converters, drivers for the triggers, an OLED screen that displays sensor information, the entire process and both manual and automatic controls are controlled by a development card. The optical system comprises an arrangement of mirrors that basically, gives the light direction of the lasers and make them impact on the same point, in the end an optical fiber is integrated to be able to enter inaccessible parts in the mouth for treatment. To validate the implemented prototype, measurements were made of both irradiance and power in specialized equipment for these applications, in addition to being based on dental journals and health articles published by different institutes and universities.

Palavras-chave : Laser; bifrequencial; mirrors; development card; irradiance.
