Cardiovascular monitoring is important to prevent diseases from progressing.\nThe jugular venous pulse (JVP) waveform offers important clinical information\nabout cardiac health, but is not routinely examined due to its invasive\ncatheterisation procedure. Here, we demonstrate for the first time that the JVP\ncan be consistently observed in a non-contact manner using a novel light-based\nphotoplethysmographic imaging system, coded hemodynamic imaging (CHI). While\ntraditional monitoring methods measure the JVP at a single location, CHI's\nwide-field imaging capabilities were able to observe the jugular venous pulse's\nspatial flow profile for the first time. The important inflection points in the\nJVP were observed, meaning that cardiac abnormalities can be assessed through\nJVP distortions. CHI provides a new way to assess cardiac health through\nnon-contact light-based JVP monitoring, and can be used in non-surgical\nenvironments for cardiac assessment.\n
