​Putting The Power Of Monitoring And Safety In Your Hands​


millimeter fiber cable runs eliminated the need for copper cable harnesses. Aesthetics of the monument improved for the public. The installation carried out in 2010 and the Monitoring is ongoing.

The Mount Rushmore National Memorial is a sculpture of the heads of four United States presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. This sculpture was carved into poor quality of the granite in the face of Mount Rushmore. The construction on the memorial began in 1927, and the presidents' faces were completed between 1934 and 1939. On-line monitoring system was installed using FBG sensors to monitor fractures and rock blocks. Hundreds of pounds of copper removed. Four, three

The characteristics and conditions of highway PR-2 in Yauco (road in the Puerto Rican component of the National Highway System) were suitable to implementation of Geosynthetic Reinforced Soil/Integrated Bridge System (GRS-IBS) technology to replace the original bridges 1121 and 1122.  These reinforced concrete slab bridges were constructed in 1970 and had a three-spans configuration with a total length of 24 meters which were replaced with two single span GRS-IBS of 11 meters. The bridge 1121 was instrumented with optical remote system which consist of 20 pressure cells (10 on each abutment in the GRS mass) to measure the superstructure’s vertical pressure distribution, and 16 geosynthetic fiber-optic sensors (8 on each abutment into the integration zone and GRS mass) to measure stresses and strains. The monitoring system is of particular importance to PRHTA because it enables comparison between design assumptions and theory, and the actual behavior of the GRS–IBS structure.

Micronoptics has participated in many projects of great importance around the world of which we can highlight:

  • ​Canton TV Tower, China​
  • ​Beijing National Stadium or Olympic Stadium "Birds Nest", China
  • Como Cathedral, Lombardy, Italy
  • Mount Rushmore National Memorial, South Dakota, USA
  • GRS-IBS at Higway PR-2, Yauco, Puerto Rico

The Como Cathedral is one of the most important buildings in the region. It is commonly described as the last Gothic cathedral built in Italy and was built in​ 1396It is 87 meters long, from 36 to 56 meters wide, and 75 meters high into the top of the cupola. It has a Latin Cross floor plan with a central nave and two side aisles, separated by pillars, and a Renaissance transept, with an imposing cupola over the crossing. In this impressive structure was installed a optical system to monitor structural settlements. About 28 sensors (16 displecement and 12 temperature sensors) were installed. This system is in use from 2007.

The Canton TV Tower is the worlds tallest broadcasting tower at 610 meters. This tower was suitable to install a system of long term monitoring of structural health.  The tower have unique design with a hyperbolic shape which consist of reinforced concrete inner tube and steel outer tube with concrete filled tube columns. About 208 fiber optic and electrical sensors were installed at five different heights on the outer tube of the tower and the antenna. The monitoring points were determined by the finite element analysis. The installed monitoring system will help to the owners to know the real behavior of this complex mechanisms during lifetime.

The Olympic Stadium "Birds Nest  was designed for use throughout the 2008 Summer Olympics and ParalympicsThe design, which originated from the study of Chinese ceramics, implemented steel beams in order to give the stadium the appearance of a bird's nestThe stadium consists of two independent structures, standing 50 feet (15.24 meters) apart a red concrete seating bowl and the outer steel frame around it. Twenty-four trussed columns encase the inner bowl. ​In this impressive stadium was installed a remote monitoring system with 300 FBG sensors and instruments of MicronOptics company. The installed remote system helped to the owners to monitoring the amazing structure during olympic events and will help them during lifetime.
