This is the image obtained from the camera when a white workpiece is placed on top of the wavelength conversion sheet and the white sheet. [Light from the white sheet and the workpiece is reflected white and
the light conversion sheet reflects orange]
This is the image obtained when a blue light is shone onto the parts. [Light from the white workpiece and the white sheet are reflected blue. The wavelength conversion sheet converts the blue light to an orange/red colour and reflects this colour]
This is the image obtained when a [blue cut filter] is added onto the front of the lens, this cuts out the reflected light in the blue range, and only allows the light from the wavelength conversion sheet to enter the lens. In this way, an image similar to that of a silhouetted image is captured whilst cutting out any reflected light from the workpiece.
