LIPA Releases Recommended Industry Practice for Measuring Speckle

Today, the Laser Illuminated Projector Association (LIPA) released to the public its Recommended Practice: Measurement of Speckle in Laboratory Conditions, a guide for laser projector makers, installers, and theater operators to measure and compare this common laser attribute caused when coherent light bounces off a rough surface. 

The practice is the first of its kind to detail procedures and equipment for obtaining a reference figure, and is being made available by LIPA at no cost as an industry service at the LIPA website at www.LIPAinfo.org/speckleRP.
 
Laser-projector manufacturers are using very effective optical designs to virtually eliminate visible speckle in their products,” noted Pete Ludé, the chairman of the working group tasked with creating the document and senior vice president of innovation at RealD. 

“But just like luminance, color, uniformity and contrast, speckle can affect the perceived image quality, so it is useful to consistently measure it using a method agreed upon by industry experts.  Projector customers, including cinemas and other public venues, will be pleased to have this recommended practice available and we look forward to their feedback through the technical committees already in place.”
 
The document was drafted over two years by 25 experts from the laser, optics and projector communities contributing their time and knowledge.  This initial document focuses on a measurement under laboratory conditions.  To the extent that the projector and screen under test are representative of an actual theater installation, it is expected that the lab measurement will correlate well with performance in the theater.  The recommended practice primarily focuses on the requirements of the projector, screen, and the camera used for the measurement.   LIPA has briefed its members and will hold a hands-on, full-day training for interested parties in early-2016. 
 
“The team has created a procedure that is accurate, repeatable, inexpensive, versatile, and returns a clear measurement,” said Matt Cowan, co-founder and CTO for Entertainment Technology Consultants and document editor.  “Our intent was to design a metric that correlates with human perception,” added Rick Posch, principal at CR Media Technologies. “We will continue to build our understanding of how human vision detects speckle, and ultimately arrive at a threshold of acceptability to sustain excellent image quality in cinema.”
 
Jan Daem, current chairman of LIPA and product validation engineer, Barco, commented, “With nearly 1 million deployed laser illuminated projectors in the field, including over a hundred at premier theater locations, this document provides a benchmark and confirms the highest possible industry performance.  We believe this is an important LIPA contribution to the rapid adoption of laser illuminated projection.”
 


About Laser Illuminated Projector Association: LIPA was founded in May, 2011 to speed the adoption of laser illuminated projectors into theaters, and other public spaces worldwide by providing the information needed to enact regulatory change and educate stakeholders.   LIPs are enabling movie theater and conference room audiences to enjoy higher quality and dramatically brighter images, especially in 3D, while lowering operating costs and reducing power consumption.
