Our scientists and engineers have brought to the market innovative and unique Laser Vibrometers and Laser Triangulation Sensors for the measurement without contact of physical quantities such as: vibration, distance, velocity. Julight represents the “Italian Excellence for Vibrations” !
The Laser Vibrometers product line is based on the smart Self-Mixing Interferometry (SMI) technology. Small-sized and lightweight optical head, and reduced manufacturing costs are obtained thanks to the simplified optical configuration of SMI. Ease of use and high value for money are unique characteristics of Julight’s products.
Julight sensors and instruments can be proficiently applied to industrial sectors (automotive, aerospace, electronics, precision mechanics), scientific research (university laboratories and research centers), building and architectural environments (structural monitoring, restoration), biomedical and biological fields.

Laser Valve Motion System
Unique, integrated solution for combustion engine valve motion measurement.
Zero-delay laser triangulation sensors supply real-time displacement of the valve with high resolution, and displacement + velocity + acceleration signal outputs.
Optional Laser Vibrometer allows subtraction of unwanted engine head vibrations
The Self-Mixing Interferometry (SMI) technology has been pioneered by Julight co-founders, and Julight owns the world’s most advanced knowledge and expertise in this field.
In SMI, the traditional concept of laser vibrometry and laser interferometry is revolutionized, in favor of an ultra- simplified optical configuration where the beamsplitter and reference arm of the interferometer are removed, leaving one single measurement path that goes straight from the laser source to the target.
Light back-reflected or back-diffused by the target re-enters into the laser cavity, where interferometric mixing occurs, and the laser simultaneously operates as light source and ultra-sensitive detector.
The use of semiconductor laser sources with small dimensions ensures high-efficiency and compact size of the measuring head. Julight explores and develops ultra-miniaturized sensors with SMI and other technologies, for consumer electronics and biomedical applications.
Julight collaborates with world-leading Companies, international Research Centers and Universities, aiming at creating new knowledge, new applications, and valuable IP.
The Innovation process at Julight starts from new ideas, goes through the validation/feasibility stage, and it is finalized by developing and assembling working prototypes and demonstrators.
Julight has a bright track-record of successful cooperative R&D and R&I Projects, carried out with worldwide Partners, or funded by National and European Institutions.
Julight expertise allows the development of any type of sensor or measuring instrument based on laser and photonic technologies, thanks to the solid know-how in light sources, photodetectors, electronic design, software and firmware, and opto-mechanical design.
Julight manufactures and markets an innovative and unique class of non-contact vibration and distance measuring sensors and instruments (laser vibrometers and triangulation laser sensors), which are based on the smart self-mixing technology (SMI).
Julight also offers state-of-the-art customized services based on the exploitation of photonic and electronic technologies, spanning from the conception and design of new measuring solutions to the realization of prototypes and small-series production.
Measurable physical quantities and properties include: distance, displacement, speed, flow, roughness, thickness, material composition, and many other metrological quantities.
