A typical CRDS setup consists of a laser that is used to illuminate a high-finesse optical cavity, which in its simplest form consists of two highly reflective mirrors.

Having said this, some groups are now beginning to develop the use of broadband LED or supercontinuum sources for CRDS, the light of which can then be dispersed by a grating onto a CCD, or Fourier transformed spectrometer ( mainly in broadband analogues of CRDS ).

* Expense: the requirement for laser systems and high reflectivity mirrors often makes CRDS orders of magnitude more expensive than some alternative spectroscopic techniques.

who left Bell Labs after using UNIX and became VP of engineering for ( now defunct ) Charles River Data Systems ( CRDS ).

Cavity ring-down spectroscopy ( CRDS ) is a highly sensitive optical spectroscopic technique that enables measurement of absolute optical extinction by samples that scatter and absorb light.

In CRDS, the ringdown time does not depend on the intensity of the laser, so fluctuations of this type aren't a problem.

The most important resonant CEAS techniques are cavity ring-down spectrometry ( CRDS ), integrated cavity output spectroscopy ( ICOS ) or cavity enhanced absorption spectroscopy ( CEAS ), phase-shift cavity ring-down spectroscopy ( PS-CRDS ) and Continuous wave Cavity Enhanced Absorption Spectrometry ( cw-CEAS ), either with optical locking, referred to as ( OF-CEAS ), as has been demonstrated Romanini et al.

In CRDS, a laser pulse is trapped in a highly reflective ( typically R > 99. 9 %) detection cavity.

CRDS sold a UNOS based 68K system, and sold porting services and licenses to other manufacturers who had embedded cpu's.

As an example, if one measures the position with an accuracy of, and the momentum with an accuracy of, then If we make further measurements in order to get more information, we disturb the system and change the trajectory into a new one depending on the measurement setup ; therefore, the measurement results are still subject to Heisenberg's uncertainty relation.

Other challenges include setup and alignment of portable telescopes for accurate tracking, working within the limitations in “ off the shelf ” equipment, the endurance of monitoring equipment, and sometimes manually tracking astronomical objects over long exposures in a wide range of weather conditions.

Combined with a long scale length, stainless steel pyramidal Fret Rails ( TM ), very low string action, and very sensitive pickups, this setup is advantageous to the tapping style of play.

Quad tape involved expensive hardware, time-consuming setup, relatively long rollback times for each edit and showed misalignment as disagreeable " banding " in the video.

The starting pitcher begins the game and he may be followed by various relief pitchers, such as the long reliever, the left-handed specialist, the middle reliever, the setup man, and / or the closer.

A team's relief staff usually consists of a closer who usually pitches the ninth inning, a setup pitcher who pitches the eighth, a middle reliever who can pitch the seventh or eighth, a left-handed specialist who pitches to left-handed batters, another middle reliever who can pitch the sixth, and a long reliever who can come in if the starter leaves the game early.
