Many applications re- quiring intricate patterns do not use mirrors due to the problems of alignment and complexity. Also, the holograms can be mass produced keeping costs to a minimum. Just thought you'd like to know. --------------------------------------------------------------------- >From the heavily-sedated terminal of ><..!decvax!ittvax!sii!dmcnh!gts Disclaimer: The content of this message is the sole responsibility of dmcnh!gts and does not necessarily reflect the policies of Datamedia. ---------------------------------------------------------------------
