HAND HELD THERMAL IMAGER (HHTI) AND LASER RANGE FINDER (LRF)

 

Parichay

 

1.  Yudhon ko itihas utna hi purana hai jitna ki manav itihas. Har yudh ke saath larai ke tariqe/ tactics aur equipments mein badlav hote rahe hain. Hamari sena mein bhi is adhunikaran ki wajah se tactics badle aur naye yantra shamil kie gaye. Is adhunikaran ke tehat abhi haal hi mein Automatic Grenade Launchers, Missiles, naye Radio Set, Multishot Grenade Launcher adi shamil kiye gaye. HHTI aur LRF bhi naye yantra hain jo abhi haal hi mein induct kiye gaye hain.

 

HHTI se Jankari

 

4.    Purane zamane mein yudh subah shuru hokar sham ko bugle bajte hi band ho jata tha. Phir samay ke saath surprise haasil karne ke liye yudh raat mein bhi lare jane lage. Is liye raat mein bhi dekhne ke liye naye tariqe ka awishkar hota raha, phir woh mashal ka istemal se lekar illuminating round, PNVD aye aur ab HHTI ka istemal ho raha hai. HHTI hamen raat, kathin battlefield condition aur kharab roshni mein dekhne ki kshamta pradan karta hai.

7.         Operation ke Sidhant.  Yeh yantra aspas ki vastuon ke tapman mein fark ko pehchan kar object/ target ko detect karta hai. Ismein tapman ke anusar object ko detect kar darshane ke liye white hot/ black hot polarity ka bandobast hai. Iss siddhant ko thermal imaging bhi kahte hain. Takniki bhasha mein yeh Forward Looking Infra Red(FLIR) ke siddhat par kaam karta hai.

 

8.         Vishestaen aur Hadbandiyan.           

 

(a)     Visheshtaen.

 

(i)           Kafi lambe range tak detect kar sakta hai.

(ii)          Andheri raat, kharab roshni, camouflage aur kohre mein bhi dekhne ki kshamta rakhta hai.

(iii)         Din ke samay bhi istemal kiya ja sakta hai.

(iv)         Zoom ka bhi bandobast hai.

(v)          Ismen LRF, video out put aur specific test equipment ke liye interface jorne ka bandobast hai.

(vi)         Nazdiki range par hathiyar aur equipment ka khaka pehchana ja sakta hai.

 

(b)     Hadbandiyan.

 

(i)            Lamba ready time.

(ii)           Battery ke karan simit operational time.

(iii)         Ghane khore, dhuen aur pedon/ jharidar ilake mein detection kam reduce ho jata hai.

 

9.    Maintenance aur Storage mein Dhyan Dene wali Baten. Kisi bhi equipment ko lambe samay tak operational/serviceable rakhne ke liye yah nihayat zaruri hai ki uski sahi dekhbhal ki jaye. HHTI ki dekhbhal mein chand ek zaruri baten is parkar hai:-

 

(a)     Safai ke dauran chemical/rashayan ka istemal na kare kyonki isse plastic aur rubber parts ka kharab hone ka khatra rahta hai.

(b)     Lens ko kapre ya rumal se saaf na karen.

(c)      Operation ke dauran battery ko puri tarah discharge na karen.

(d)     Battery ko kholne ka prayas na karen, isse explode hone ka khatra ho sakta hai.

(e)     Batteryko aisi jagah na rakhen jahan par tapman 65^oC se adhik ya -20^oC se kam ho.

(f)       Short term storage mein 0 degree se 25 degree celsius tapman mein rakhen. Battery pratidin apni capacity ka 1% lose karti hai.

(g)     Long term storage ke dauran har 12 mahine mein battery ko recharge karen.

 

LRF se Waqfiat

 

11. Kisi bhi target par kargar fire girakar usko barbad karne ke liye uske range ka sahi andaza lagana nihayat zaruri hai. Pehle ham halving aur Section average jaise tarikon se range ka andaza lagate the par ab LRF se accurate range pata lagana sambhav hai.

14. Principle of Operation. Iska operation echo ke sidhant par adharit hai. Ek adrishya (invisible) high intensity ki infra-red light target par transmit ki jati hai aur reflected light wapas receive ki jati hai. Is infra-red light ka target ko hit kar wapas ane ka time electrically napa jata hai aur phir isko automatically doori mein badla jata hai.

 

15. Reticle Pattern. LRF mein target par aim karne ke liye aur range dikhane ke liye ek reticle pattern diya gaya hai. Ise neeche chitra mein darshaya gaya hai.

16. Filter Assembly.Yeh kam range wale target ki duri ko napne ke kam ata hai. Iske istemal se eye safe distance 800m se ghatkar 125m ho jati hai, par saath hi maximum range bhi 6000m tak ho jati hai. Iska istemal amuman 1km se kam duri wale target ka range napne ke kaam ata hai. 

 

17. Yadi aap HHTI ka sahi istemal kare toh paramparik yudh aur counter terrorist operation ki halat mein dushman aur terrorist ki ghuspaith /movement ko samay par detect kar action le sakte hai. Saath hi LRF ke zariye range measure kar kisi bhi target par bahut hi accurate fire dalkar barbad kiya ja sakta hai.
