What is the principle of projector?

In simple language, a projector basically adopts the operational principal of image projection whereby the projector accepts a video/image input, processes it with the assistance of its inbuilt optical projection system consisting of a lens & optical source and projects the enhanced output on the Projection screen.

What is the purpose and working principle of profile projector Explain with neat sketch?

Optical profile Projector Working principle (Construction) A beam of light from the light source is passed thru the condenser lens(C) and Projection lens(P) and fall on the Screen. the workpiece will be placed in between the light source and condenser lens. A shadow image of the workpiece will be created.

What is meant by profile projector?

Also known as an optical comparator, or even called a shadowgraph, a profile projector is an optical instrument that can be used for measuring. This projection screen displays the profile of the specimen and is magnified for better ease of calculating linear measurements.

What are the advantages of profile projector?

Advantages. Profile Projector can reveal imperfections such as burrs, scratches, indentations or undesirable chamfers which both micrometers or calipers can’t reveal. They’re able to measure in 2-D space.

Which type of lamp is used in profile projector?

Halogen Lamp
Profile Projector RPP-3000 Projection Light Source with 24V / 150W Halogen Lamp. Double Oblique Light source for Surface Illumination.

What is the purpose of projector?

A projector is an output device that can take images from a computer and display them on a screen, wall or another surface. The surface projected onto is usually large, flat and lightly colored. There are either still (slides) or moving images that can be produced by projectors.

What is the profile projector used for?

Profile projector is widely used for complex shape stampings, gears, cams, threads and comparing the measured contour model. It’s easy to use and highly efficient. It is a commonly used measurement of optical instruments.

What are the typical applications of profile projector?

It is a commonly used measurement of optical instruments. Thus, profile projector is widely used in major machinery manufacturing including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels and etc.

What is the purpose of a profile projector?

Profile projector, also known as contour comparator, is widely used to measure 2-dimensional data. An optical comparator (often called just a comparator in context) or profile projector is a device that applies the principles of optics to the inspection of manufactured parts.

What is the work principle of a projector?

Work Principle. The projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to examine or measure.

How does a light emitting diode projector work?

Light-emitting diode projectors represent a significant advance over traditional projectors. Instead of using a bulb filled with gas at high pressure, they use an array of LEDs to generate the light that shines through, or off of, the image element to project an image.

What kind of components are in a laser projector?

It consists of a housing that contains lasers, mirrors, galvanometer scanners, and other optical components. A laser projector can contain one laser light source for single-color projection or three sources for RGB (red, green, and blue) full color projection.
