shaiqbashir Posted April 30, 2006 Report Share Posted April 30, 2006 Hi guys!well me, in a robot thinking of using an infra red LED and a detector to track a line made up of a white reflector tape often used in cars. someone just told me that the infra red gets absorbed in a white surface and cannot get reflected. Is it true?if yes then what idea should i use?Thanks in advance!take carez Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 30, 2006 Report Share Posted April 30, 2006 Hi Shaiq,Something that looks white reflects all colors, usually including IR.Something that looks black absorbs all colors. Quote Link to comment Share on other sites More sharing options...
ZomBiE Posted May 12, 2006 Report Share Posted May 12, 2006 But even black reflects IR, and even in visible spectrum if it has enough intensity. Quote Link to comment Share on other sites More sharing options...
