Instruments that measure light at the edges of an object, such as a surface or a cloud.
When a person walks on the ground, a “vertex” is the point where the light of the sun and the light from distant objects appear to hit.
In a car, an “observation” is when the light source from a car or a bicycle appears to come from a particular location.
The term “laser measurement instrument” refers to a laser instrument that uses lasers to measure the position of light and its direction.
A “direct measurement instrument”, also called a “light source” or “light detector”, is a type of instrument that measures light coming from a specific object.
Laser measuring instruments are often used in medical settings to measure blood pressure or heart rate.
A “lasersight” is an instrument that emits a laser beam and then uses an imaging sensor to measure light intensity.
The intensity of the light is then compared with a standard of measurement.
Direct measurement instruments use lasers to detect the position and intensity of light coming at the object.
They also use imaging sensors to measure motion.
Both direct and laser measuring instruments can measure multiple objects, and they are usually used in combination.
An example of a direct measurement instrument is a headlamp that uses a light source to detect objects that are close together.
A direct measurement is typically more precise than a laser measuring instrument because it can use less energy and is more sensitive.
If a direct measuring instrument has a beam of light at a particular point, a direct measure can be used to measure more than one point at the same time.
Another example is a laser detector that uses an image sensor to detect a specific point on a surface, and then an imaging device to measure another point nearby.
