Fiber optic light sensor

Environmental Monitoring and Assessment, 2015
We describe a low-cost fiber optic sensor for measuring photosynthetically active radiation (PAR) in turbulent flow. Existing technology was combined in a novel way for probe development addressing the need for a small but durable instrument for use in flowing water. Optical components including fiber optics and a wide-spectrum light detector were used

Optically driven optically addressed spatial light modulator

Optical Society of America Annual Meeting, 1992
Most optically addressed spatial light modulators (OASLMs) have had the disadvantage of requiring some kind of electrical drive field, along with the optical read and write fields. The preliminary results of research into an optically driven optically addressed spatial light modulator (ODOASLM) employing a polymer as the photoreceptor indicate that the

Controlling Light with Light: Optical Bistability and Optical Modulation

1979
A simple GaAs etalon has been used to observe optical bistability, pulse shaping, and modulation of one light beam by another. Such devices may lead to all-optical, high-speed computation and communication; all-optical signal processing may be appropriate with the advent of low-loss, high bit-rate optical transmission systems.

Optical tweezers: a light touch

Journal of Microscopy, 2012
SummaryOptical tweezers use focused laser light to manipulate microscopic particles. We discuss the underlying physics of the technique in terms of a gradient force exerted by the light on the particles. The versatility of optical tweezers is highlighted, in particular, we explain how spatial light modulators and various imaging methods have greatly ...
