Spectroscopic and Sensing Devices Research Group (SSDRG)

Spectroscopic and Sensing Devices Research Group (SSDRG) is one of the key research units under National Electronics and Computer Technology Center. Equipped with high caliber research staff recognized nationally and internationally, SSDRG aims to create innovative spectroscopic sensing devices and systems that are appropriately applied in a variety of applications such as food and agriculture, health and medical sector, energy and environment, national security, manufacturing and service industry, and community and rural area sector.

Our work start from proving concept ideas and creating related core technologies. Then we push them into prototype levels that are close to or associated with the need or the requirement from the target users.
