Light is everywhere around us in the form of sunlight, artificial lighting and signaling. Most electrical equipment use either visible or infrared radiation for signaling, displays, sensing, data read-out, or digital communication. Colour is one of the most significant properties in consumer products.

Metrology research of Optical Radiation Measurements is divided into three branches:

  • Radiometry deals with characteristics of light sources and detectors
  • Photometry studies light as humans see it, and
  • Spectrophotometry investigates optical components as well as the optical properties of materials.

Some of the facilities, developed in the laboratory, are at world-leading level, when comparing accuracy, compactness, and operating costs. The group's research concentrates on electronics, modern optics and optical radiation measurements.

Metrology Research Institute is a joint laboratory between Aalto University and MIKES. It is involved in many national and international projects. Most of the research in the laboratory is currently carried out within the frameworks of EURAMET EMRP and EMPIR.

The Institute is the national standards laboratory for optical quantities in Finland, maintaining national standards of optical quantities and carrying out calibrations at the highest level.

The research group is led by Professor Erkki Ikonen. For other staff members, see Aalto People - Signal Processing and Acoustics (note that not all profiles are public). See our detailed project descriptions for information about specific contact persons for each activity.

Photometry

Photometry is the measurement of visible light as perceived by humans. Our current focus is on increasing the accuracy of the energy efficiency measurements of novel light sources, such as LEDs and OLEDs.

Radiometry

Radiometry deals with techniques for measuring electromagnetic radiation, in the form of ultraviolet radiation, visible light, and infrared radiation.

Spectrophotometry

Spectrophotometry focuses on measuring the amount of light that a sample or an object absorbs or reflects as a function of wavelength using an instrument known as a spectrophotometer.

Electrical instrumentation

Off-the-shelf measurement equipment are not always available, and dedicated measurement devices are often built at Metrology Research Institute.
