Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A video imaging system, and more particularly, a modular video imaging system having a control module connectable to multiple input modules. The input modules each capable of receiving differing types of image data from different types of cameras including stereoscopic camera configurations and processing the image data into a format recognizable by the control module. The control unit providing general functions such as user interface and general image processing that is not camera specific including the generation of a 3D image stream formed by combining two image streams.
