Real-time monitoring of LED greenhouse lighting
Ocean Insight
29 May 2020

Controlling the quality and yield of crops will be crucial elements of increased food production. Growing crops in greenhouses and vertical farms (greenhouse factories) will allow us to better control the process of growing food and, in the case of vertical farms, move food production closer to the consumer (vertical farms can be integrated into existing structures such as warehouses). In greenhouses, LEDs are a popular lighting option to provide the spectral energy to crops for photosynthesis and other growth processes.

This whitepaper will explore how optical sensing is used for real-time monitoring of LED greenhouse lighting, and how this can be used to manage colour and power output.

Analysing lidar return signal strengths for target optical surfaces and atmospheric conditions

Lidar systems are complex, dynamic devices involving both optical, mechanical, and electronic components that must work together while interacting reliably with a widely varying external environment. It is the optical part of the system that interacts with the environment, and so it is through optical modeling that we can gain a crucial insight into expected performance under varying conditions.

In this paper, we will take a brief look at how illumination ray tracing software can be used by engineers to gain these insights into expected lidar system performance before building expensive prototype systems.

Freeform optical elements give optical designers new and exciting degrees of freedom when it comes to designing optics for illumination applications. These same freeform elements can also add a new layer of complexity to the design process due to added degrees of freedom.

Understanding the differences in high-power pulsed and CW damage
BRL Laser Damage
01 April 2020

All of us who work with high power lasers have experienced laser damage, usually when we least wanted to. Sometimes just an unexpected flash of light means an optic needs to be replaced, but often the case is far worse where a single coating damage can lead to systemwide failure. Much of our work is certifying optics for pulsed laser systems in order to prevent this kind of catastrophic event.

This whitepaper dicusses in scientific detail the laser damage caused by pulsed and CW high-power systems.
