Non-contact flood and moisture detector

ActiveUS8248256B1Reduce radiation levelsAlarmsSpecular reflectionField of view

A non-contact flood and moisture detector for detecting water on remote surface includes a source of IR radiation directed towards the remote surface and projecting a field of illumination on the remote surface, and a receiver of IR radiation directed towards the remote surface, and collecting the IR radiation from a field of view on the remote surface, with the field of illumination and the field of view at least partially overlapping. A portion of the IR radiation is backscattered and received by the receiver and a portion of the IR radiation is specularly reflected and not received by the receiver. An electronic circuit synchronized with the source and the receiver compares the IR radiation measured by the receiver to a dry baseline condition level where a decrease in the backscattered IR radiation measured by the receiver indicates the presence of water.

In optical disc drive, laser diode is used, and also HFM (High Frequency Module) oscillator is used to reduce laser mode hopping noise. Big EMI noise is radiated by the HFM current for optical noise reduction, or by the switching current for write-strategy of recording. Then conventionally, shield was required in order to reduce EMI noise radiated by the current driving a laser diode. By giving a jitter to the HFM signal superimposed to the current of laser diode or switching signal by write-strategy for recording, a spectrum is diffused and the peak value of an EMI noise is reduced.
