- Solarimeter
A solarimeter is a pyranometer , a type of measurement measuring device used to measure combined direct and diffuse solar radiation . An integrating solarimeter measures energy developed from solar radiation based on the absorption of heat by a black body . The principle this instrument was designed on was first developed by the Italian priest, Father Angelo Bellani . He invented the Actinometer actinometric method which is based on physical and chemical techniques. ref cite web title Figure 8.

File Hukseflux huksetrackv1.jpg thumb right 350px Example of a pyrheliometer on a solar tracker which keeps the instrument pointed at the sun. A black shadow band keeps the pyranometer shaded, so that it measures diffuse radiation only. The global solar radiation is then calculated from direct and diffuse radiation.

Sunlight enters the instrument through a window and is directed onto a thermopile which converts heat to an electrical signal that can be recorded. The signal voltage is converted via a formula to measure watts per square meter ref http www.global greenhouse warming.com pyrheliometer.html ref . It is used with a solar tracking system to keep the instrument aimed at the sun. A pyrheliometer is often used in the same setup with a pyranometer . Standards Pyrheliometer measurement specifications are subject to International Organization for Standardization ISO and World Meteorological Organization WMO standards. Applications Typical pyrheliometer measurement applications include scientific meteorological and climate observations, material testing research, and assessment of the efficiency of solar collector s and Photovoltaics photovoltaic devices .

- Radiometer
Image Crookes radiometer.jpg thumb 210px An example of a Crookes radiometer . The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity. A radiometer is a device for measuring the radiometry radiant flux power of electromagnetic radiation . Generally, the term radiometer denotes an infrared radiation detector, yet it also includes detectors operating on any Electromagnetic radiation electromagnetic wavelength. A common example is the Crookes radiometer , an early model device wherein a rotor with dark and light vanes in a partial vacuum spins when exposed to light. The Nichols radiometer operates on a different principle and is more sensitive than the Crookes type. A microwave radiometer operates in the microwave wavelengths. The radiometer contains argon gas to enable it to rotate. The Microelectromechanical systems MEMS radiometer, invented by Patrick Jankowiak, can operate on the principles of Nichols or Crooke and can operate over a wide spectrum of wavelength and particle energy levels. ref http patft.uspto.gov netacgi nph Parser?Sect1 PTO2&Sect2 HITOFF&p 1&u 2Fnetahtml 2FPTO 2Fsearch bool.html&r 3&f G&l 50&co1 AND&d PTXT&s1 7,495,199&OS 7,495,199&RS 7,495,199 MEMS Radiometer United States Patent 7,495,199 ref See also Radiation pressure Net radiometer Pyranometer Radiometry Spectroradiometer References reflist External links commons Radiometer http www.weburbia.com physics light mill.html Explanation of Crooke s Radiometer Category Electromagnetic radiation meters Category Radiometry ca Radi metre cs Radiometr da Radiometer de Radiometer fr Radiom tre io Radiometro it Radiometro he mk ja pl Radiometr pt Radi metro ru fi Radiometri sv Radiometer uk zh ... more details

Image Actinograph 1846.png right thumb 300px Description of R. Hunt s Actinograph. ref John Timbs, The Year book of Facts in Science and Art, London Simpkin, Marshall, and Co., 1846 ref Image HD Actinograph.jpg right thumb 300px Hurter & Driffield s Actinograph. An actinograph is an instrument for measuring or estimating the amount of light available, in terms of its ability to expose photographic film . That is, it measures the actinic or chemical intensity of light, as opposed to radiometry radiometric or photometry optics photometric amount of light. The earliest actinographs were 24 hour recording devices, using a rotating cylinder of photographic paper exposed through a wedged shaped slit to record a graph of actinic light during the period of a day hence the graph suffix in actinograph . Such devices were developed and described by Robert Hunt scientist Robert Hunt , secretrary of the Royal Cornwall Polytechnic Society in 1845, as an improvement on T. B. Jordan s 1839 Heliograph . ref Klaus Hentschel, Mapping the Spectrum Techniques of Visual Representation in Research and Teaching , Oxford University Press, 2002, ISBN 0 19 850953 7. ref In 1888, Ferdinand Hurter and Vero Charles Driffield patented a device for estimating the actinic power of sunlight and for computing exposure times and apertures for cameras, based on the film speed plate speed , time of day, time of year, and latitude. These were slide rule s, not measuring instruments, and did not produce a graph, but Hurter and Driffield adopted the same name for it.

- SCR-658 radar
The SCR 658 radar was developed in conjunction with the SCR 268 radar . It was preceded by the SCR 258. Its primary purpose was to track weather balloons. Prior to this it was only possible to track weather balloons with a theodolite , causing difficulty with visual tracking in poor weather conditions. The set is small enough to be portable and carried in a Ben Hur trailer .
