SINGLE VISIBLE MULTI-SPECTRAL OPTICAL SYSTEM WITH INTEGRATED LASER RANGE

摘要

1. A single pupil multispectral optical system with an integrated laser range finder, containing a common input channel, a spectrodividing plate reflecting the spectral range of the television channel and transmitting the spectral range of the thermal imaging channel, and two optical channels for each of the spectral ranges, characterized in that the thermal imaging channel is located in the passing through the spectrodividing plate, the direction is made two-component, and the first and second components are made in the form menisci, and its optical axis is offset relative to the optical axis of the common input channel, the reflected television channel is made of two-component, between the components of which there is a spectrodividing cube that transmits the spectral range of the television channel and reflects the rangefinder channel containing collimating two-component optics, the first component of which is made in the form of a positive lenses, the second in the form of a negative lens, a quarter-wave phase plate, a polarizing splitter, branching the first rangefinder channel to the emitting and receiving parts, each of which contains a two-component pairing lens, the first component of the pairing lens made in the form of a positive lens, and the second in the form of a negative meniscus, with the following relationships: where δ is the offset of the optical axis of the channel passing through the spectrodividing plate relative to the optical axis of the common input channel; d is the thickness of the spectrodividing plate; n is the refractive index of the spectrodividing plate for the average
