Light isanalogous in many ways to sound and many of the equations used to describe sound also apply to light, but there are limitations. Sound waves don't really polarize the way light waves do for example. Light also displays some characteristics of particle behavior that contradict its wave behavior - again making it different from sound.
Sound is not convertible directly to light, though it can be used to attenuate electrical signals, which in turn can be used to cause variations in the output of a light source powered by those signals.
SONAR is an acronym for Sound Navigation And Ranging. LIDAR would use light.

'Sound and safe', usually expressed as 'safe and sound' means being very safe; being free from danger and from injury or ill-health. The phrase is frequently used when something, often a person, has been missing and then found in good health, or good condition. 'Safe' speaks for itself; 'sound' is from an old usage in English, indicating good health: 'sound in body and mind', 'sound in limb', or 'sound in wind', meaning respectively mentally and physically healthy, having arms and legs in good working order, or having good lung capacity.
A home scanner as in a copier scanner? If so than it is only a bright light used to reflect the image of what you are scanning and as so is as safe as any light.

For me, I used to cleaned my surrounding everyday, that is way I always kept it cleaned and safe.
