Lazer masofa o'lchagich - bu nishongacha bo'lgan masofani aniq o'lchash uchun lazerdan foydalanadigan asbob. Lazer masofa o'lchagich ishlayotgan vaqtda nishonga juda nozik lazer nurini chiqaradi va nishon tomonidan aks ettirilgan lazer nurini fotoelektr elementi qabul qiladi.
Agar lazer uzluksiz yondirilsa, o'lchash diapazoni taxminan 40 kilometrga yetishi mumkin va operatsiya kechayu kunduz amalga oshirilishi mumkin. Agar lazer impulsli bo'lsa, mutlaq aniqlik odatda past bo'ladi, lekin uzoq masofali o'lchash uchun yaxshi nisbiy aniqlikka erishish mumkin.
Dunyo'ning birinchi lazeri birinchi marta 1960 yilda Amerikaning Hughes Aircraft Company olimi Maiman tomonidan ishlab chiqilgan. Tez orada AQSh armiyasi shu asosda harbiy lazer qurilmalari ustida tadqiqot olib bordi. 1961 yilda birinchi harbiy lazer masofa o'lchagich AQSh armiyasining namoyish sinovidan o'tdi, shundan so'ng lazerli masofa o'lchagich tez orada amaliy konsortsiumga kirdi.
The laser rangefinder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders, so it is widely used in terrain measurement, battlefield measurement, tanks , ranging from aircraft, ships and artillery to targets, measuring the height of clouds, aircraft, missiles and artificial satellites, etc. It is an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery.
Lazerli masofa o'lchagichlarning narxi pasayishda davom etar ekan, sanoat asta-sekin lazerli masofa o'lchagichlardan foydalanishni boshladi. Sanoat o'lchash va nazorat qilish, minalar, portlar va boshqa sohalarda keng qo'llanilishi mumkin bo'lgan tezkor, kichik o'lchamli va ishonchli ishlashning afzalliklari bilan uyda va chet elda bir qator yangi miniatyura masofa o'lchagichlari paydo bo'ldi.
