A Three-Wavelength Pulse Oximeter for Carboxyhemoglobin Determination
Pulse oximetry measures the relative concentration of arterial oxygenated hemoglobin and reduced hemoglobin. This paper presents the design of a pulse oximeter, which measures the presence of a third substance, carboxyhemoglobin (HbCO), by unfiltered LEDs at 660 nm, 810 nm, and 940 nm. Background information is given on the theory of pulse oximetry. Theoretical approximations and calculations w...

متن کاملWavelength-selective planar holograms.
Planar gratings and holograms are normally readout-wavelength insensitive. We show, however, that a binary phase surface-relief hologram can be transparent at one wavelength (lambda) yet diffract efficiently at another (lambda'), provided that the phase delay is an integer number of waves (e.g., 3) at lambda and a half-integer number of waves (e.g., 2.5) at lambda'. We fabricated a 7.9-microm-d...
متن کاملA hybrid pump wavelength assignment scheme for optical packet switch with parametric wavelength converters
This paper proposes a pump wavelength assignment scheme for an optical packet switch with parametric wavelength converters (PWCs) to reduce the number of different colored light sources while a predefined packet loss rate is satisfied. PWCs are separated into two sets. First set, each PWC has a different pump wavelength from each other. Second set, all PWCs have the same pump wavelength placed ...
