PLX Lateral Transfer Hollow Retroreflectors (LTHR’s™) will be a part of the Alignment Monitoring and Control System (AMCS) of the ATLAS program.
PLX was awarded a contract from Ball Aerospace & Technologies Corporation for two LTHR’s™ for the Advanced Topographic Laser Altimeter System (ATLAS) program. ATLAS is the sole instrument on the ICESat-2 satellite scheduled for a June 2018 launch.
The two LTHRs™ are part of the Alignment Monitoring and Control System. They are used to keep the laser and receiving telescope bore-sighted to each other during orbit.
The Ice, Cloud and land Elevation Satellite-2, or ICESat-2, will measure the height of a changing Earth – one laser pulse at a time, 10,000 laser pulses a second. Slated for launch in 2018, ICESat-2 will carry a laser altimeter that detects individual photons, allowing scientists to measure the elevation of ice sheets, sea ice, forests and more in unprecedented detail.
PLX was also awarded a contract by NASA for a 5-inch clear aperture, 18.5 inch offset LTHR™ as part of the ground support equipment for testing the ATLAS system before launch. This LTHR™ provides a return beam from the laser to the receiving telescope to allow validation of the system.
Additional recent satellite projects utilizing PLX Hollow Retroreflectors include the Meteor–M satellite and the Canadian Astro-H Metrology System, as well as units delivered to ABB Bomem for the ACE-FTS, the main instrument on SCISAT-1. This Canadian satellite was designed to make observations of the Earth’s atmosphere.
PLX’s "Metrology System for Inter-Alignment of Lasers, Telescopes, and Mechanical Datum” abstract / manuscript accepted at SPIE for inclusion in their Library of Technical Papers.
In modern scientific and industrial laser applications, inter-alignment of multiple optical devices is frequently a basic requirement to meet a certain specification and performance.
However, the designed optical system combining mechanical elements, lasers and optical sights in various wavelengths frequently deviates from specified goals due to real life imperfections and effects. These may include mechanical tolerances, optical distortion, heating, laser cavity misalignment, overall instabilities, and non-linear effects.
In order to deliver accurately and produce intricate optical systems, a carefully designed method for interalignment is required completing and updating the already existing methods. Thus, we designed and upgraded the performance of an electronic autocollimator and combined it with innovative mechanical manipulation of optical invariants such as a Lateral Transfer Hollow Periscope to greatly improve and expand inter-alignment procedures.
Metrology System for Inter-Alignment of Lasers, Telescopes, and Mechanical Datum: Poster Presentation at OPTIFAB.
Advances in sensor technology have opened the door to new measuring instruments, initiating the development of the new PLX, ACT-25 and ACT-HR Electronic Autocollimator and Alignment Telescope Systems.
The technology is based on autocollimation principles combining laser beam collimation and direction measurement, accurate telescopic measurement, focusing techniques with sophisticated software and computing techniques. Of special interest is the laser analyzing autocollimator since it combines laser-analyzing technology with angular reflection technology.

A laser is aimed at each of the units, which returns the beam parallel to itself with a known offset to a two-dimensional detector. Any shift of the units will be read as an offset on the detectors.
Geophysics Interferometer: Long-baseline laser strainmeter in Kamioka uses PLX 15” clear aperture Hollow Retroreflector.
A few hundred meters beneath the surface of the Earth at the Kamioka Underground Observatory, a new laser strainmeter (LSM) is being built. The strainmeter is a highly asymmetrical Michelson type interferometer. The long arm will be 1.5 km in length and will be in an evacuated beam tube. This will be the longest LSM in Japan and one of the largest in the world.
The 1.5 km strainmeter will offer higher sensitivity and resolution than the current “100 meter interferometer” in use at Kamioka. The LSM will be used for geophysical research such as crustal motions, gravitational geophysics, earth tides, fault activities and the Earth’s free oscillations. In addition to this research the LSM will be supporting other experiments at Kamioka, such as the KAGRA project whose aim is to detect gravitational waves.
As part of the Geophysics interferometer, PLX manufactured a 15” clear aperture Hollow Retroreflector of 0.5 arc seconds accuracy for the University of Tokyo Earthquake Research Institute. The instrument was mounted on a super-invar custom-made bracket and utilized PLX light-weighted optics technology. PLX also participated in the original “100 meter interferometer” with our standard 2.5”, 0.5 arc second OmniWave Retroreflector.

PLX has been named a “STAR SUPPLIER” by Lockheed Martin.
This award signifies PLX’s ability to meet the high-quality standards and delivery requirements for the company.
In 2001, PLX was asked by Lockheed Martin to develop a Modified Boresight Module (MBSM) for the Apache Arrowhead program, using a military version of the PLX Lateral-Transfer Hollow Retroreflector (LTHR™). The MBSM improved accuracy of the existing system from 30 arc minutes to 1 arc second. This was a particularly difficult task because of the state-of-the-art accuracy of this requirement and of the battlefield conditions under which the instrument must operate. Working closely with Lockheed Martin personnel, the MBSM was successfully designed and qualified. PLX continues to provide MBSMs for the Arrowhead program.
PLX has also received the U.S. Small Business Administration’s Subcontractor of the Year Award for 2008, Lockheed Martin’s Small Business of the Year Award for 2003, 2006 and 2007, The Lockheed Martin Eagle Award of Excellence for 2007 and the Northrop Grumman Corporation Bronze, Silver and Gold Supplier Quality Awards, among many other awards.
PLX honored with the SBA 2008 subcontractor of the year award in Washington D.C.
The award PLX received is granted by the United States Small Business Administration for SBA’S Region 2 covering several states in the northeast and is sponsored by the U.S. Chamber of Commerce. Three days of ceremonies were held in Washington DC, including a reception at the White House where President Bush was the keynote speaker.
Among the other featured speakers were former Speaker of the House Newt Gingrich, Secretary Mike Leavitt, U.S. Department of Health and Human Services, Ambassador Susan C. Schwab, United States Trade Representative, David Latimore of the Initiative for a Competitive Inner City, John Bryant of Operation HOPE, Michael Porter of Harvard University School of Business, other prominent business leaders, CEOs and politicians.
M.O.S.T.™ achieves superb optical stability, unsurpassed shock and vibration resistance and sub-arc second accuracy between optical elements.
Developed by PLX, Monolithic Optical Structure Technology (M.O.S.T.™) is a unique optical innovation that combines all of the elements of a complex optical setup into a single monolithic unit. This technology represents a significant improvement over existing systems that utilize traditional mirror mounts. Traditional mechanical mounts are inherently unstable and require constant adjustment – a true disadvantage in critical applications requiring the permanent and stable fixed positioning of optical elements. Optical engineers typically use M.O.S.T.™ monolithic assemblies in applications such as laser cavities, beam dividers, beam delivery systems, and boresighting. However, by using M.O.S.T.™ you can simplify and improve practically any lab setup you need to convert into an instrument.
