| dc.description | We demonstrate experimentally the detection, in
a remote and noncontact manner, of human life signs using a
high-sensitivity pulsed laser vibrometer. The high surface displacement
detection sensitivity of the photo-electromotive-force
(photo-EMF) pulsed laser vibrometer, combined with its tolerance
to the presence and moderate temporal variations of optical
speckles in the light beams, allows the detection of human heartbeats,
breathing, and gross physical movement from essentially
any part of a human subject’s surface, even in the presence of
clothing, all the while without limiting the interrogation points to
specific locations like the chest and carotid areas. In contrast to
conventional Michelson interferometer-based laser vibrometers,
the photo-EMF pulsed laser vibrometer (PPLV) does not require
the use of retroreflective tapes or special electronic filtering to
retrieve vividly the biological subject’s life signs. Experimental
results demonstrating the detection of life signs from various parts
of biological subjects’ bodies, with or without the coverage of
clothing are presented. We also demonstrate the monitoring of a
human subject’s heart movements by interrogating the back of
his/her hand. Results from using PPLV to determine extremity
blood circulation at various levels of proximal occluding pressures
are also presented. | |
