  • Interesting fact: Methylphenidate (Ritalin) is a medication prescribed for individuals (usually children) who have an abnormally high level of activity or attention-deficit hyperactivity disorder (ADHD). According to the National Institute of Mental Health, about 3 to 5 percent of the general population has the disorder, which is characterized by agitated behavior and an inability to focus on tasks. Methylphenidate also is occasionally prescribed for treating narcolepsy. Methylphenidate is a central nervous system (CNS) stimulant. It has effects similar to, but more potent than, caffeine and less potent than amphetamines. It has a notably calming effect on hyperactive children and a "focusing" effect on those with ADHD.

    • n agitation The act of agitating, or the state of being agitated. The state of being shaken or moved with violence, or with irregular action; commotion: as, the sea after a storm is in agitation.
    • n agitation Disturbance of the mind; perturbation; excitement of passion.
    • n agitation Examination of a subject in controversy; deliberation; discussion; debate.
    • n agitation The act of arousing public attention to a political or social question by speeches, etc. Synonyms Agitation, Trepidation, Tremor, Emotion, excitement, flutter. Tremor is, in its literal use, wholly physical; it may be in a part of the body or the whole; it is generally less violent than trepidation. Trepidation and agitation are more often used of the mind than of the body. But all three words may express states either of the body or the mind, or of both at once through reflex influence. Trepidation is generally the result of fear; it is the excited anticipation of speedy disaster, penalty, etc. Agitation may be retrospective and occasioned by that which is pleasant; it includes the meaning of trepidation and a part of that of emotion. Emotion is used only of the mind; it is the broadest and highest of these words, covering all movements of feeling, whether of pleasure or pain, from agitation to the pleasure that the mind may take in abstract truth.

Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
For integration times (cid:29) the period of agitation the recorded image is a pattern that (ideally) does no longer contain any modal information.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
In order to obtain the most efficient agitation, the fibre is secured on two points where the second point of securing is chosen at a larger distance from the point of agitation (see fig. 2).
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
An agitation frequency of 80 Hz (fig. 4(a)) gives the best agitation results (low SNR in the respective exposures), and the modal pattern achieves a low contrast.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
Operating the agitation device at higher frequencies does not visibly improve the contrast, nor could a significant change in SNR be observed.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
From laser exposures it appears that additional manual agitation would improve the result, but again no difference for the SNR-value could be measured.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
These are supplemented by a set of exposures recording the fibre in the agitated state.
Modal noise prediction in fibre-spectroscopy I: Visibility and the coherent model
In order to remove any instrumental signature (e.g. beating pattern due to the bandpass-filter), the unagitated fibre exposures are flat-fielded against the exposures of the agitated fibre.

After calculating the modal noise for the unagitated fibre exposures, the same procedure was applied to the exposures of the agitated fibre to compare with the theoretical photon noise, which was directly derived from Poisson statistics.

With a few exceptions, all agitated fibre modal-noise values match with the theoretical photon noise, while always achieving significantly higher SNR-values than for the unagitated fibre.
