Industry Case Study: DSPL’s FlexLink

July 1st, 2015|Underwater Imaging|

We developed a unique transmission method for uncompressed HD-SDI video signals in subsea use known as FleXlink™. After FleXlink was validated in the lab, we partnered with Woods Hole Oceanographic Institution (WHOI) to conduct field trials of the technology.

Advancements in Subsea High Definition Imaging

March 1st, 2015|Underwater Imaging|

We are guided by several basic principles when creating any new product design. Performance, immersion longevity, durability, and compact form factor are just a few of the underlying concepts considered a necessity for any product that bears our name. This article discusses how these philosophies are applied to our development of High Definition imaging systems, including the FleXlink technology.

Understanding the Basics of Underwater Lighting

May 1st, 2013|Technical Resources, Underwater Imaging|

In subsea photographic and video imaging applications, one of the challenges that system designers, integrators, and operators face is bringing along all of the light they will need for tasks below depths of about 150 to 250 m. At these depths, an understanding of how light propagates through water helps designers and users balance mission requirements against the real-world constraints of underwater lighting while helping them make informed lighting choices.

Nano SeaCam®

November 3rd, 2011|Underwater Imaging|

The Nano SeaCam underwater video camera is a high resolution camera in a tiny package that goes deep. With a diameter of only 25mm (0.985”) and a length of 88.2mm (3.47”), including the connector, the Nano SeaCam provides quality video in a truly tiny package.

LEDs are Now the Choice for Underwater Lights

May 1st, 2011|Underwater Imaging|

Properly designed underwater LED lights can be “plug & play” replacements for halogen lights. They can operate using the same wide choice of connectors, the same input power (120VAC or low voltage DC), and the same dimming controls (variable voltage or phase control dimming) as the halogen lights that they replace. This makes it easy for underwater operators to significantly upgrade the lighting that they use without encountering complex or costly changes in the process.

Advanced Underwater LED Power Supply and Light Control

May 20th, 2010|Technical Resources, Underwater Imaging|

While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit. LEDs are tiny, fragile devices that will be easily damaged if allowed to overheat or if exposed to excessive voltage or currents. These devices need an external electronic circuit, commonly called a driver, to safely control the power applied to them. This article will look at the driver circuitry behind the light emitters.
