Accuracy and precision of cryogenic limb array etalon spectrometer (CLAES) temperature retrievals

Etalon Array Reconstructive Spectrometry

Compact spectrometers are crucial in areas where size and weight may need to be minimized. These types of spectrometers often contain no moving parts, which makes for an instrument that can be highly durable. With the recent proliferation in low-cost and high-resolution cameras, camera-based spectrometry methods have the potential to make portable spectrometers small, ubiquitous, and cheap. Her...

AccucheckInform II: About Its Accuracy and Precision

Fiber-optic Temperature Sensor Semiconductor Etalon

This paper describes a fiber-optic temperature sensor that uses a spectrum-modulating Sic etalon. The spectral output of this type of sensor may be analyzed to obtain a tem.+ perature measurement which is largely independent of the transmission properties of the m sensor's fiber-optic link. A highly precise laboratory-type spectrometer is described in detail, and this instrument is used to stud...

An all-cryogenic THz transmission spectrometer

This article describes a THz transmission spectrometer for the spectral range of 2–65 cm ~100 GHz to 2 THz! with a spectral resolution of at least 1.8 cm ~50 GHz! where the source, sample, and detector are all fully contained in a cryogenic environment. Cyclotron emission from a two-dimensional electron gas ~2DEG! heated with an electrical current serves as a magnetic-field tunable source. The ...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
