Etalon Array Reconstructive Spectrometry

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...

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...

From Reconstructive Triangle to Reconstructive Quadrangle: Time to Include Tissue Distraction in the Reconstructive Algorithms

Extreme pulse-front tilt from an etalon

Angular dispersion—whether from prisms, diffraction gratings, or etalons—is well known to result in a pulsefront tilt. Focusing into a tilted etalon, in particular, generates a huge angular dispersion, which is very useful for high-resolution spectrometers and pulse shapers. Here we demonstrate experimentally that, due to the large angular dispersion 3° /nm , the pulse directly out of an etalon...
