What is a stadimeter used for?

A stadimeter is an optical device for estimating the range to an object of known height by measuring the angle between the top and bottom of the object as observed at the device.

When was the stadimeter invented?

The stadimeter was developed in the 1890s by Bradley Allen Fiske (1854-1942), a Lieutenant in the United States Navy who had access to a laboratory in New York City that was fully backed by the Western Electric Manufacturing Co.

Who invented stadiometer?

This page describes a widely recognized tool for assessing spinal shrinkage, the Stadiometer. It was invented by Jurgen Eklund and Nigel Corlett, then of the University of Nottingham, to measure shrinkage in stature.

Are stadiometer accurate?

Accuracy More Precise Measurements using a stadiometer are clearly more accurate to use. Especially with the base stadiometer, the measurement is clearly more stable to do. So that the measurement results must be more precise.

How do you use a sextant?

To use a sextant to find the angle of elevation of an object, you’ll need to know your elevation above sea level. Sight the horizon by looking through the horizon mirror, then move the sextant’s index arm until the object you’re trying to find is also visible on the horizon.

Can I measure myself with a tape measure?

Find or buy a non-elastic tape measure, which will conform best to your body and provide the most accurate measurements. Measure yourself wearing as little clothing as possible, and pull the measuring tape snug to the body without indenting the skin.

Can a sextant be used during the day?

Horizontal sextant angles can usually be taken any time during the day or night. During the day, you can measure the horizontal angle between two visible objects. The most important thing is to be able to positively identify the objects that you are measuring so that you can plot them accurately on your chart.

What is A stadimeter used to measure?

A stadimeter is an optical device for estimating the range to an object of known height by measuring the angle between the top and bottom of the object as observed at the device. It is similar to a sextant, in that the device is using mirrors to measure an angle between two objects but differs in that one dials in the height of the object.

Who invented the stadimeter in 1942?

A Mk 5 Mod 0 US Navy Stadimeter made in 1942 by Schick Inc. of Stamford CT. The hand held stadimeter was developed by Bradley Allen Fiske (1854–1942), an officer in the United States Navy.

What is A stadimeter on a submarine?

Stadimeter. It is one of several types of optical rangefinders, and does not require a large instrument, and so was ideal for hand-held implementations or installation in a submarine’s periscope. A stadimeter is a type of analog computer .

What is a digital stadiometer?

Digital stadiometer with close up insert of the device’s headpiece. A stadiometer is a piece of medical equipment used for measuring human height. It is usually constructed out of a ruler and a sliding horizontal headpiece which is adjusted to rest on the top of the head.
