Claim Text:
1. A device for the non-invasive measurement of a person's blood pressure parameters comprising: a first optical module comprising an optical source of coherent light configured to provide light to a second optical module, said first optical module included in a wearable system configured to be worn on the person; the second optical module included in the wearable system, the second optical module comprising optics configured to be worn proximal to the person's skin, to deliver said coherent light to a sub-dermal region of the person, and to receive light reflected from said sub-dermal region; an optical connection configured to couple light between the first optical module and the second optical module; a hologram recorded in a non-transitory medium, said hologram not obtained directly from said person, said hologram configured to provide time dependent interferometric optical information from optical interference using said coherent light reflected from said sub-dermal region; an electronic imaging system configured to transform the time dependent interferometric optical information into a digital format; and a processing module configured to receive the time dependent interferometric optical information in a digital format and to calculate blood pressure parameters therefrom.
