Foif 100 series Total station reflector less mode technology


This is a great news to Foif Lovers, there has been a recent advancement in Foif 100 series total station technology: the reflectorless measuring technique.  I refer to this technology as “reflectorless”, “prismless” or “direct reflex”.   This is a feature that surveyors had dreamed of for decades before it became available and now Foif 100 series has incorporated and embrace its technology and come up with one. It is a fantastic tool for topographic work and avoids the many vicious, barking dogs that wait just across the fence where you need to locate an existing structure, among other things. The applications for construction layout and as-build’s are plentiful as well.

Without going into the technical explanations of how this works, the technology allows for measurements to objects or points without the need of placing a prism at those points. This is a great time-saver when points are difficult or impossible to reach.  It also improves safety when you need to determine positions on elevated structures, false work, or any point that is dangerous and time-consuming to reach.  Some examples are: measuring to structural steel, checking the clearance heights of overhead power lines, measuring objects that are inaccessible or across obstructions, checking the position of forms prior to a pour, etc.

At first the technology was limited by range and measuring beam-width issues, but with Foif 100 series most of this limitations have been overcome.  Reflectorless range has been extended to up to 600 meters.  Accuracy of reflectorless total station measurements are as good as +/- (1 mm + 1ppm).  Of course, when no person is required to place the reflector at the point being measured, measurements become a one-person operation, saving labor costs.  When clever support application software compliments this capability the applications and benefits increase even more. These programs allow measurement into corners, measuring to objects that have obstructions between them and the total station and automated measurement of a series of points, to name a few.

One situation that limits the use of the reflectorless capability has to do with the angle of incidence. For the measurement beam to return to the total station (which is how the distance is determined) the object being measured must be within a certain range of angles relative to it.  A good example is a long roadway.  At a certain distance from the total station the angle to the surface will become too shallow and the measurement beam can no longer return to its source.  There are tricks to mitigating this problem; placing the instrument much higher than the surface being measured, or making multiple instrument setups.  As these limitations on apply only to long or very wide horizontal surfaces they are not encountered very frequently by users.

Almost every Foif models has reflectorless models, but what makes Foif 100 series more special that deserve this coverage, is the price, its affordable and user friendly to both surveyors and civil engineers, also The range, accuracy and other specifications are sufficient for use on the job site.so do your homework visit measurement systems ltd and investigate this model, inquire free demonstration.
