Description

В существующих световых дальномерах используетс  модул ци  света по  ркости с переменной или посто нной частотой.Existing light range finders use luminance modulation with variable or constant frequency.

Рассто ние при помощи их определ етс  как функци  разности фаз посланного и отраженного световых сигналов. Это требует наличи  в дальномерах сложных электрических и электронных устройств.The distance is defined as a function of the phase difference between the sent and reflected light signals. This requires the presence of complex electrical and electronic devices in range finders.

Предлагаемый световой дальномер обеспечивает более простое решение задачи, позвол ет использовать источник света меньшей мощности , обладает более высокой точностью и помехоустойчивостью, имеет значительно более простую аппаратуру.The proposed light range finder provides a simpler solution to the problem, allows using a light source of lesser power, has higher accuracy and noise immunity, and has a much simpler apparatus.

Сущность изобретени  заключаетс  в том, что в передающем устройстве дальномера применены пол ризатор, линейно-пол ризующий световой поток, даваемый помещенным в устройстве источником света, и вращающее (или качающее) плоскость его пол ризации приспособление (например,  чейка Керра или  чейка Фараде ), а в приемном устройстве - пол риметр, измер ющий угол поворота в плоскости пол ризации ,  вл ющийс  функцией определенного рассто ни .The essence of the invention is that in the transmitting device of the range finder a polarizer is used, linearly polarizing the luminous flux given by the light source placed in the device and rotating (or swinging) the plane of its polarization (for example, Kerr cell or Farad cell), and in the receiver there is a polarimeter measuring the angle of rotation in the polarization plane, which is a function of a certain distance.

На чертеже показана схема устд ойства дальномера.The drawing shows a diagram of the device range finder.

Прибор имеет следующие основные части: / - источник света с необходимой оптикой; 2 - пол ризатор; 3 -  чейка Керра или Фараде ; 4 - оптика дл  направлени  света в приемное устройство; 5-генератор сдвинутых по фазе переменных напр жений или генератор мен ющегос  по величине тока; 6 - пол риметр.The device has the following main parts: / - light source with the necessary optics; 2 - polarizer; 3 - cell Kerr or Farad; 4 — Optics for directing light to a receiver; 5-generator of phase-shifted alternating voltages or alternating current generating current; 6 - floor meter.

Принцип действи  прибора состоит в следующем.The principle of operation of the device is as follows.

На одном конце линии А, длина которой измер етс , помещаетс  приспособление 3, вращающее или качающее плоскость пол ризации выход щего из пего света ( чейка Керра или Фараде ), а на другом конце Б той же линии находитс  пол риметр 6, в котором наблюдаетс  свет, выщедщий из Л.At one end of line A, the length of which is measured, is placed the fixture 3, the rotating or swinging plane of polarization of the light emanating from it (Kerr cell or Farad), and at the other end of B of the same line there is a polarimeter 6 in which light is observed squeezed out of L.
