What's the difference between pantograph and polygraph?
Pantograph
Definition:
(n.) An instrument for copying plans, maps, and other drawings, on the same, or on a reduced or an enlarged, scale.

(16) Twenty pantographic recordings were transferred to the Stuart fully adjustable articulator.
(17) A clinical experiment was undertaken to study the relationship between occlusal therapy and pantographic reproducibility.
(18) Using this technique a stable centric relation position can be maintained during the maxillary cast mounting procedure and the subsequent setting of the articulator to the pantographic recordings.
(19) Even after removing and reinserting the clutches several times, retention is sufficient to support the weight of the pantograph.
(20) Pantographic tracings were made and transferred to the semiadjustable articulator.
Polygraph
Definition:
(n.) An instrument for multiplying copies of a writing; a manifold writer; a copying machine.
(n.) In bibliography, a collection of different works, either by one or several authors.
(n.) An instrument for detecting deceptive statements by a subject, by measuring several physiological states of the subject, such as pulse, heartbeat, and sweating. The instrument records these parameters on a strip of paper while the subject is asked questions designed to elicit emotional responses when the subject tries to deceive the interrogator. Also called lie detector
Example Sentences:
(1) Polygraphic recordings during sleep were performed on 18 elderly persons (age range: 64-100 years).
(2) Polygraphic and videotape recordings, carried out for several nights, showed that after nearly each REM period, he would wake up briefly, presenting eye blinking followed by a burst of generalized hypersynchronous theta to start his seizures.
(3) Twelve-hour polygraph recordings were made before and at various intervals after basal forebrain damage in a total of eight cats.
(4) Nine subjects who underwent a severe head traumatism with a brainstem dysfunction at the acute stage, were polygraphically recorded at the chronic stage under strict conditions of drug withdrawal and light-dark periods.
(5) The diagnostic differential between narcolepsy and idiopathic hypersomnia may be difficult in those cases which clinically manifest only hypersomnia and the nocturnal polygraphic study does not show any differences between both diseases, particularly when the beginning of REM sleep is not presented in narcoleptic patients.
(6) As a method for identifying sleep disorders it has greater merits than conventional methods of polygraphic recordings.
(7) Polygraphic 23-hr recordings were carried out in 25 adult cats in order to examine the effects of both systemic and local injections of various histaminergic and antihistaminergic drugs on sleep-waking cycles.
(8) One hundred and seventy-three full-term newborns with hypoxic encephalopathy were subjected to polygraphic recordings (EEG, EOG, ECG and respiration) of 2.5-3.5 hr duration in the first 3 weeks in the period from 1970 to 1986.
(9) Yet the clinical picture, the child's personality and the polygraphic electroencephalographic recordings suggest that it should be treated sooner and more often than is usually done.
