A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of pressure with high sensitivity and stability. The advance in tactile sensing ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

A new fiber-optic sensor made from stretchy rubber rather than glass can be integrated into wearable electronics and measure movement. The sensors can also quantify the force of stretching, bending, ...

Researchers have developed a tiny fiber optic force sensor that can measure extremely slight forces exerted by small objects. The new light-based sensor overcomes the limitations of force sensors ...

At some time or another, we’ve all had an idea we thought was so clever that we jumped on the Internet to see if somebody else had already come up with it. Most of the time, they have. But on the off ...

Knight Optical’s extensive range of Moulded Optics meets the demands of the most complex, high-specification projects. From Quartz Tubes and Aspheric Lenses to sought-after Germanium Windows and ...

Smartphone cameras have improved dramatically since the first camera-equipped cell phone was introduced in 1999, but they are still subject to tiny errors in the alignment of different wavelengths of ...

Optical imaging methods are rapidly becoming essential tools in biomedical science because they're noninvasive, fast, cost-efficient and pose no health risks since they don't use ionizing radiation.

Assessing spinal curvature is one of the key aspects of diagnosing back pain and related disabilities, and deformation of the vertebral column (VC) can cause anything from minor pain to immobility.
