LASTEC develops Optical Target Locater

Laser Science and Technology Centre (LASTEC), Delhi, has designed and developed an Optical Target Locater (OTL), a laser-based portable surveillance device, for detection of passive or active optical threats. The system functions in the cat’s eye effect. Any optical system, when illuminated by a laser beam, returns some back-scattered energy. This retro-reflected energy helps in locating optical targets against a static background. The system is an important tool for detection of any active or passive surveillance

A device using the retro-reflected signal from their front-end optics. Any surveillance device with front-end optics and a sensor at the focal plane, whether biological, i.e., eye or passive sensors like binoculars, day sight
or night vision device (NVD), or electronic sensors as in Laser Range Finders (LRFs) can be detected by this approach. The threat could be in terms of a sniper equipped with a day sight or an NVD, or any other optical/electro-optical surveillance device, viz., binoculars, surveillance cameras, LRF, designators, etc. Two variants of the OTL are being developed.

The development of short range version, OTL 300, for 300 m range has been completed. OTL 1500, the long-range version, is presently undergoing test and optimization process. OTL 300 finds application in active scanning and monitoring of specific areas, VIP security and detection of pointed optics. The equipment has been demonstrated to potential users like Delhi Police, National Security Guards and Indian Army and was recently deployed for area sanitation and security on several occasions. Delhi Police is procuring OTL 300.

Poor build quality
Looks like something from the 70s

Even the picture is terrible

How is it when compared to it's western & eastern counterparts

Who cares how it looks , It should prove its self in Battled that's whet matters

Give it to CRPF. Recent recoveries from naxal hideouts show that naxals have aquired a large no of monoculars and PNVs. It will be of great help in anti naxal and anti insurgency ops in Kashmir and NE.

DRDO scientists develop device to track snipers​

BENGALURU: Defence scientists have developed a device that can identify snipers, providing a boost to security agencies. "This new-age device can detect passive or active optical threats like telescopes, binoculars or the telescopic sight of a sniper rifle, and has proven effective for VIP security," a source said.

Not surp risingly, Delhi police, who protect the most number of the country's VVIPs and VIPs, will be the first to equip itself with this new-age device. Called the Optical Target Locater (OTL), it has been developed by defence scientists at Laser Science and Technology Centre (LASTEC), primarily for the armed forces.

Sources in LAST EC, a DRDO lab, said: "It is a laser-based portable surveillance device which functions on the cat's eye effect," adding that the device releases a laser beam which scans a designated area and as soon as it hits any of the targets (anything optical) some bac k-scattered energy is received and the target is detected.

"This retro-reflected energy helps in locating optical targets against a static background. Any surveillance device with front-end optics and a sensor at the focal plane, whether biological, like eye, or passive sensors like binoculars, day sight or night vision device (NVD), or electronic sensors as in Laser Range Finders (LRFs) can be detected by this approach," he explained.

The threat could be in terms of a sniper equipped with a day sight or a NVD, or any other optical/electro optical surveillance device, like binoculars, surveillance cameras, LRF, designators, etc.

Confirming to TOI on Delhi police's interest in the device, special commissioner (security) SBK Singh, said: "There is certainly a requirement for this and we've raised it."

Two variants

Sources in LASTEC said Delhi police are looking at procuring OTL 300. "It will have a range of 300 metres, which they will buy," a source said. It is effective in scanning and monitoring of specific areas, VIP security and detection of pointed optics. Another long-range device, OTL 1500, is undergoing test and optimization process, and will be used by the Indian Army, National Security Guards and other agencies.
