Joseph Rice is the originator of this technology where a low cost B&W CCD
camera with near infrared LED array is used to read the veins beneath the skin.
Joseph Rice est à l'origine de cette technologie, où une caméra CCD N&B munie de LED
émettant dans le proche infra-rouge éclairent le réseau veineux situé sous la peau.
Extracted vector patterns are used to identify the coordinates of branch points,
and generate a unique vein map signature.
Un squelette du réseau veineux est extrait,
d'où on identifie les emplacements des embranchements qui sert à générer une signature unique.
PosID has proposed (U.S. Patent # 5,351,303) to read the thermal image
of the fingertip using an infrared camera (Merlin camera from Indigo Systems Inc. using
a 320 x 240 microbolometer array and filters optimized for 7- to 8-µm detection).
PosID a proposé (brevet US 5,351,303) de lire l'image thermique du bout du doigt
en utilisant une caméra infra-rouge (caméra Merlin d'Indigo Systems, basée sur une matrice
de 320 x 240 microbolomètres plus un filtre optimisé pour la détection dans la bande des 7 à 8 µm).
(2000) Next step is to integrate a microlens array directly
on a CMOS sensor in order to manufacture a flat sensor.
(2000) La prochaine étape est d'intégrer un reseau de microlentilles directement
sur un capteur CMOS dans l'objectif d'obtenir un capteur plat.
Luminetx (now Christie+) proposes a device able to read the vein pattern,
and to project the image directly on the skin, the VeinViewer, which is not directly biometrical recognition
but very close.

(via TampaBay).
Palm vein sensor
(2009 Apr) Fujitsu, partnering with Allscripts, recently introduced the
Allscripts Patient Kiosk
for health care patients to confirm their identities, using the PalmSecure.

Hand Vein Authentication (Fujitsu Palmsecure)
(2006 Dec) Actiontech CREDO is announced as a fingerprint reader on the Actiontech english website, which is NOT a
fingerprint reader, but looks like to be the Fujitsu reader...
(2017 May) EPFL's Security and Cryptography Laboratory joined forces
with startup Global ID to develop an encryption technique
for processing biometric data captured via 3D finger vein recognition.
