using optical means, i.e. using infrared, visible or ultraviolet light

Full Title

Mechanical means for transferring the output of a sensing member; Means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting; Transducers not specially adapted for a specific variable > using optical means, i.e. using infrared, visible or ultraviolet light
