Welcome to the Instrumentation Physics Laboratory.

The Instrumentation Physics Laboratory (IPL) is one of the research laboratories in the National Institute of PhysicsCollege of ScienceUniversity of the Philippines Diliman. The main research concerns of the IPL are in the fields of optics and photonicsvideo and image processing, and complex systems in nature and society. We employ experimental approaches and mathematical modeling to address real-world problems of practical importance. Our laboratory promotes an atmosphere of learning and collaboration among teachers, graduate, and undergraduate students in building a scientific tradition in the Philippines.
