Abstract
An optical sensor that provides lateral viewing while maintaining light polarization is disclosed according to one embodiment of the invention. The sensor includes a sensor body, at least one waveguide and at least one refractive optical element. The sensor body may includes proximal end and a distal end. The waveguide includes a proximal end coincident near the proximal end of the sensor body and a distal end coincident at a point near the distal end of the sensor body. The waveguide may include one or more fiber optic. The waveguide may be positioned within the sensor body. The refractive optical element may be positioned within the sensor near the distal end of the waveguide and may be configured to refract light received from the distal end of the waveguide outward from the sensor. The refractive optical element may include one or more prisms.
