Abstract: There is a need to reduce the cost and size of functional terahertz devices, in order to expedite this notoriously underutilized frequency band toward practical applications. Electronic ...

ABSTRACT: The potential of photocatalysis for degrading water pollutants has attracted considerable attention. This research aims to investigate the fabrication of an optical sensitive Cerium ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Even plants have their favorite colors. Photosynthesis requires light, but plants don’t use all the colors that make up white light. Use a spectroscope to explore the absorption and transmission of ...

Playing with light and rainbows is a fantastic project for spring and summer. In this easy STEM Project we are making a Spectroscope which is perfect for the classroom or summer camp. As educators, we ...

Here at Hackaday, we love it when someone picks up the ball from a previous project and runs with it. That’s what we’re all about, really — putting out cool projects that just might stimulate someone ...

During the middle of World War II, teenage physics major Roy Glauber found himself plucked out of college on the East Coast and assigned to work at a mysterious new government research center in the ...

Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit ...

In this experiment, the stable output of a dual-frequency laser source is obtained by an acousto-optic modulator due to the Bragg diffraction effect. Furthermore, the non-polarized dual-laser ...

A very simple and color-observable homemade Raman spectroscope with easy preparation is introduced by simply adding low-cost components (a transmission diffraction grating sheet, a magnifying glass, a ...

Play around with optics long enough and sooner or later you’re probably going to want a spectrometer. Optical instruments are famously expensive, though, at least for high-quality units. But a useful ...
