BREAKTHROUGH IN INDIGENOUS E/O SENSOR TECH
A heartening new indigenous development could take care of India’s overdependence on foreign suppliers for critical electro-optical sensors for surface payloads. The DRDO’s Instruments Research and Development Establishment (IRDE) in Dehradun has developed a Stabilised electro-optical Sight (SEOS) with two-axis stabilisation and an integrated automatic video tracker facility. The indigenous SEOS has three electro-optical sensors, 3rd generation 3-5 μm (640 x 512 FPA) thermal imager (TI) with optical zoom, colour day TV with optical zoom camera and eye-safe laser range finder (ELRF). The day TV camera and TI sport a narrow field of view (NFOV) of 0.8° x 0.6° and wide field of view (WFOV) of 5° x 4° with additional 2 X electronic zoom in TI. These sensors provide a recognition range of 7 km for a NATO type of target. ELRF provides range of the target from 200 m to 9,995 m with an accuracy of ± 5 m.
