The two main parts of a mortise lock. Left: the lock body, installed in the thickness of a door. This example has two bolts: a sprung latch at the top, and a locking bolt at the bottom.
they can measure surfaces through transparent medium such as glass or plastic film; non-contact measurement may sometimes be the only solution when the component to measure is very soft (e.g. pollution deposit) or very hard (e.g. abrasive paper). Vertical scanning: Coherence scanning interferometry; Confocal microscopy; Focus variation
An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves.. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.
Use a soft tape measure like the ones used for sewing. Measure loosely to give your dog enough room in his costume. Next, measure your dog's chest. Begin at the front legs and measure around the body.

This area is also equal to the area of the parallelogram A"ABB". The measuring wheel measures the distance PQ (perpendicular to EM). Moving from C to D the arm EM moves through the green parallelogram, with area equal to the area of the rectangle D"DCC". The measuring wheel now moves in the opposite direction, subtracting this reading from the ...
Only when a full ten marks are counted, is there alignment, because the tenth mark is 10/10—a whole main scale unit—short, and therefore aligns with the ninth mark on the main scale. (In simple words, each VSD = 0.9 MSD , so each decrement of length 0.1 adds 10 times to make one MSD only in 9 divisions of vernier scale division).
