1. A sensor comprising:
- a sensor body; and
an emitter and a detector disposed on the sensor body, wherein the emitter and the detector are adapted to operate in a transmission mode, and wherein the sensor body is adapted to hold the emitter and detector at a substantially fixed optical distance relative to one another when the sensor is applied to a patient.

Abstract
A sensor for pulse oximetry or other applications utilizing spectrophotometry may be adapted to reduce motion artifacts by fixing the optical distance between an emitter and detector. A flexible sensor is provided with a stiffening member to hold the emitter and detector of the sensor in a relatively fixed position when applied to a patient. Further, an annular or partially annular sensor is adapted to hold an emitter and detector of the sensor in a relatively fixed position when applied to a patient. A clip-style sensor is provided with a spacer that controls the distance between the emitter and detector.
