TEMPERATURE MEASURING APPARATUS FOR PRINT CARD AND AIR VELOCITY MEASURING APPARATUS

摘要

A mirror is moved in parallel to a print card toreflect the infrared radiation radiated from the print card.The reflected infrared radiation is detected by a detectorsuch as an infrared camera though a wind rectifying platewhich can permeate the infrared radiation but interrupts theair stream between the inside and outside of a card rack.The signal corresponding to the detected infrared radiationis processed by a personal computer to measure thetemperature distribution.
