Services

Julight’s expertise in photonic systems and measuring techniques
enables to offer state-of-the-art CUSTOMIZED SERVICES:

Consultancy and solutions
development/exploitation of laser and photonic technologies
applied to industrial environment and scientific research.

Design and realization of prototype
and mini-series systems

aimed at the measurement of mechanical and metrology quantities
(distance, displacement, speed, flow, roughness,
thickness, material composition, etc.).

On-site measuring campaigns
performed using Julight’s innovative sensors/instruments,
for  customers who prefer not to buy a complete laser system
(we provide full solutions: from preliminary system study,
to measurements data analysis).

Bells characterization

Main task was to verify / demonstrate the applicability of laser vibrometry for the characterization of musical instruments, and in particular of bells. In this context, the laser vibrometry is a candidate as a viable alternative to traditional measurement techniques (based on microphones), allowing to obtain, for each bell, the different resonance frequencies (i.e., sound notes), […]

Heart beat and cardiovascular system analysis

The monitoring of the heart beat and other parameters related to the cardiovascular system is requested in the clinical context in order to perform the diagnosis of many pathologies and dysfunctions. In the last years, different devices for testing and analyzing the operating state of the global cardiovascular system of patients have been widely developed. […]

Vibration Measurements by Laser Techniques on Rotating Micro-Tools

Non-contact vibration measurements performed by laser techniques are extremely interesting for applications in all cases where the object under test shall not be perturbed by the physical contact with a sensor. Among the different approaches, the most used is Laser Doppler Velocimetry (LDV), that offers a high resolution and good versatility, and has also been […]

Vibration measurements in hot industrial environments

Non-contact vibration measurements performed by laser techniques are extremely interesting for applications in all cases where the object under test shall not be perturbed by the physical contact with a sensor or when the testing condition does not allow to use traditional techniques based on accelerometers, i.e hot objects/surfaces. Julight Laser Vibrometers allow to perform […]

Contactless vibration measurements on 5 kW power transformer

Vibration measurements are extremely important in industrial fields in order to test the quality of a product or the similarity between the project and the final product and to detect local defects during the casting process. Traditional techniques are well represented by accelerometers that allow to measure the acceleration of the displacement/vibration. Their main problem […]

Vibration measurements of different types of cement

Analysis of dense cements and related materials such as polymer cement concrete (PCC) is significant to produce original innovative components for different types of building and structures. These materials can present elevated functional proprieties (e.g. ageing resistance, cracks formation, durability, hardness and stability of mechanical modules) and they can be used for various purposes, for […]

Vibration measurements for the evaluation of the detachment of plaster

The evaluation of the phenomenon of detachment of the plaster inside and outside of buildings is a problem that can not be overlooked, since it is often a prelude to the sudden fall of pieces of plaster or ceiling that may be dangerous to people. A non-invasive approach that can be useful to the objective […]
