FIELD: machine building.SUBSTANCE: invention relates to optical-electronic systems for remote probing of underlying surface, and particularly to on-board remote Earth probing optical systems of spacecraft. Multichannel unit comprises a focal unit on optical base of which are installed charge coupled photodetector arrays with and a cell assembly on frame of which there are electronic cells. Multichannel unit has a cooling system, connected with spacecraft thermal control system. Communication of cooling system with spacecraft thermal control system is carried out by attachment of heatsink on outer side of block body, located on back side of focal unit and parallel thereto.EFFECT: technical result is provision of uniform temperature field of optical base and minimisation of its heating by electronic unit cells; reduction of weight and dimensions of unit; simplification of adjustment and testing of unit.5 cl, 3 dwg |
