When was the optical disk invented?
The optical disk was invented in 1958 by David Paul Gregg. He created a system called the Laser Optical Storage System (LOSS) that used a laser beam to record data onto a transparent disc.
What is an easy definition of the optical axis?
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
What is electro-optical system?
An electro-optical system involves the integration of electronics and optics to manipulate and control light for various applications. This system uses electrical signals to modulate and transmit light to achieve functions such as sensing, imaging, and communication. Examples include laser systems, digital cameras, and optical sensors.
What is the difference between the optical axis and the visual axis?
The optical axis is an imaginary line that passes through the center of a lens or mirror, while the visual axis is the line connecting the fovea (center of the retina) to the object being viewed. The optical axis is used in optics to describe the path of light through a lens system, while the visual axis describes the line of sight in relation to the eye.
Who invented the optical system designed to detect imperfections in repeating patterns?
The optical system designed to detect imperfections in repeating patterns was invented by Joseph Marie Jacquard in 1804. His invention revolutionized the textile industry by automating the process of creating complex woven patterns.
What is Thermo-optical analysis?
Thermo-optical analysis is a technique used to study the interaction between temperature and optical properties of a material. It measures how the refractive index or other optical properties of a material change with temperature, providing insights into its thermal behavior and potential applications in optics, photonics, and thermal management.
What did Ellen ochoa invent?

When is light a ray and when is it not?
Rays are used to model the propagation of light through an optical system
How cardinal point of optical system located?
he points on the optical axis of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.
What is the purpose of a spot diagram in optical design?
A spot diagram in optical design is used to analyze and visualize how well a lens or optical system focuses light. It helps designers understand and improve the performance of the system by showing the distribution and quality of the focused light spot.
What did Ellen Ochoa discover?
Ellen Ochoa discover optical analysis systems
What is the cardinal point of optical system?
The points on the optical axis OO' (see Figure 1) of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.
What are the different optical power units used to measure the intensity of light in optical systems?
The different optical power units used to measure the intensity of light in optical systems are diopters and watts. Diopters measure the refractive power of a lens, while watts measure the total power of light emitted or transmitted through a system.
What is a definition of telescope?
A telescope is an optical system used to make objects, especially distant objects, appear larger/closer.
