Abstract: A sensing system comprising a light filtering apparatus configured to pass a first wavelength of light corresponding to an emission spectrum characteristic of Mercury. The sensing system comprises a sensor configured to receive light passed by the light filtering apparatus and produce a sensor response that is indicative of the light passed by the light filtering apparatus. The sensing system comprises a processor configured to use the sensor response to distinguish between light emitted by a fluorescent light source and light emitted by a light emitting diode.

Abstract: An apparatus comprises a display screen, and an optical sensor module which is disposed behind the display screen. The optical sensor module further comprises a light emitter operable to generate light having a wavelength for transmission through the display screen toward a target object. A light sensor is operable to sense light reflected by the target object and having the wavelength. A reducer is arranged for reducing the optical power density by increasing a diameter of a light beam generated by the light emitter on the display screen, wherein the reducer is disposed between the light emitter and the display screen so as to intersect the light beam generated by the light emitter.
