Measurer Laser

What Kinds of Laser Hair Removal Equipment are Available?

Now that you have made the decision to undergo laser hair removal therapy, you are probably curious as to the types of laser hair removal equipment. The good news is that the technology has come so far over the multiple decades of its existence that there are now many options for both at-home and salon/doctor's office use.

One of the first pieces of equipment you should understand is a tool which measures the precise coloring of your skin and hair colors, so that the clinician can know the precise type of equipment and equipment setting which will best suit you individually.

In addition there being numerous different models and types of laser equipment which are commonly used today, it should be noted that each of these devices is highly customizable based on the attributes of the individual receiving the treatment.

 One adjustable characteristic of laser equipment is that there are varying wavelengths of laser lights used in treating different individuals. Wavelengths are measured in nanometers. There are three different wavelengths which are commonly used today: Alexandrite, which is at 755 nanometers, Pulsed Diode Array, which is at 810 nm, and Nd: YAG, at 1064 nm. While Alexandrite is considered the most effective wavelength, it can only be used on individuals with light-colored skin; Nd: YAG is most commonly used for individuals with darker skin.

Another aspect of laser equipment that is adjustable is the pulse-width of the laser beam. Individuals with darker skin tone often are treated with longer pulse-widths, although it is believed that shorter pulse-widths are more effective in treating hair.

Other aspects of laser equipment which are adjustable include the width of the laser beam, the energy level used, and the repetition rate of laser pulses. The proper settings for each of these parameters will be determined by the facets of the individual receiving the treatment. The technician or clinician performing the laser hair removal procedure will select the proper equipment and settings for each client.

Understanding the science behind the process can be a liberating tool for someone considering laser hair removal. In addition, having an idea about exactly what the machines that you will be facing can help to alleviate the nervousness one might feel before going for his or her first treatment.

In addition, knowing that this technology has been advancing for decades and that great strides have been made to make it safer as well as more customizable can help you feel confident that you will be in good hands.

How Do I Accurately Measure the Contours of a Surface From Distance ?

I know various electronic measuring devices exist to give the distance of a surface from the measurer. Such as hand held surveying tools etc using a laser beam etc.

But is it possible to get a very accurate measurement of an entire rugged surface of a structure from a distance of several metres away ? Such as the surface of a rock face or the carved wall of a building ?

This is actually relatively easy and the technology is used in several industries, notably the automobile industry.

Essentially, you use an optical projector to project multiple parallel line, scattered dot or more complex encoded patterns on the surface. These projected patterns are then picked up by multiple cameras and a computer calculates the surface from the distortion of the patterns.

In case of parallel stripes a flat surface will reflect parallel stripes. If the surface is curved, the stripes will appear closer in some places and wider apart in others. From that one can calculate the local angle of the surface relative to the projecting beam and from that, by integration, the absolute contour. But there are much more advanced test patterns than that.
