OPTICAL DATA INSERTION DEVICES

摘要

An optical data insertion device for an optical system includes a projector operable to insert additional optical data into a capture aperture of the optical system so as to provide a combined image and a reflection barrier. The reflection barrier includes a secondary filter and a primary filter adapted to fit over the rest of the capture aperture of the optical system. The secondary filter is a band pass filter adapted to allow the transmission of a narrow pass band centred on the peak emission wavelength of the projector. The primary filter is a narrow band stop filter that blocks the transmission of a narrow band of light corresponding to that allowed to pass by the band pass filter.

1. An optical data insertion device for an optical system comprising:
a projector operable to insert additional optical data into a capture aperture of the optical system so as to provide a combined image; and a reflection barrier comprising: a primary filter adapted to cover the capture aperture of the optical system, the primary filter having an aperture or cutaway portion aligned with the light emitted by the projector into the capture aperture.
