摘要

Optical device for calibration dynamics pressure transducers respiratory, equipped with a function generator (1) that excites through an amplifier (2) a speaker (3) coupled to a chamber (4) of known volume, being determined sliding cone with optical laser beam in a consistent (5) system reflected by a mirror (6) attached to the speaker cone hits the surface sensitive offset photodetector (7).
