An LED night-light includes a housing and first and second prongs extending out of the housing. A light-emitting diode is mounted to the housing and is configured to emit a first color of light. Circuitry is electrically connected to the light-emitting diode. The circuitry is configured for energizing the light-emitting diode when the first and second prongs are inserted into an electrical outlet connected to a power source. A color filter is mounted on the housing. The color filter is configured to filter the first color of light emitted from the light emitting diode to produce at least a second color of light different from the first color of light.

A high performance imaging system for diffuse optical tomography is disclosed. A dense grid utilizing sources, e.g., light emitting diodes ('LEDs'), that achieve high performance at high speed with a high dynamic range and low inter-channel crosstalk are complemented by a system of discrete, isolated receivers, e.g., avalanche photodiodes ('APDs'). The source channels have dedicated reconfigurable encoding control signals, and the detector channels have reconfigurable decoding, allowing maximum flexibility and optimal mixtures of frequency and time encoding and decoding. Each detector channel is analyzed by dedicated, isolated, high-bandwidth receiver circuitry so that no channel gain switching is necessary. The resulting improvements to DOT system performance, e.g., increased dynamic range and decreased crosstalk, enable higher density imaging arrays and provide significantly enhanced DOT image quality. A processor can be utilized to provide sophisticated three dimensional modeling as well as noise reduction.
