Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Conditions on Early Earth

Conditions on Early Earth

Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.

Classical Conditioning

Classical Conditioning

Associative learning, a core principle in behavioral psychology, involves forming connections between events and facilitating learned responses. This concept is vividly illustrated by classical conditioning, a process extensively studied by the Russian physiologist Ivan Pavlov. Pavlov's pioneering research on dogs' digestive systems led to the discovery that behaviors can be learned through association, laying the groundwork for classical conditioning.
Ivan Pavlov observed that dogs...

Conditions of Equilibrium

Conditions of Equilibrium

Equilibrium refers to a state where a rigid body is not subjected to any translational or rotational motion. This state is achieved when the force and couple acting on a rigid body equal zero. When the system of external forces results in a net effect equivalent to zero, the rigid body is considered to be in equilibrium.
Internal forces are not considered for conditions of equilibrium because they occur in equal and opposite pairs within the body, effectively canceling each other. As a result,...

Operant Conditioning

Operant Conditioning

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Area of Science:

Optical Engineering
Metrology
Surface Science

Background:

Stitching interferometry is a common technique for measuring large optical surfaces.
Systematic errors from measuring instruments and stage imperfections can compromise accuracy.
Existing methods often rely on reference surfaces or are susceptible to translation errors.

Purpose of the Study:

To define conditions for reconstructing stitched mirror profiles free of systematic errors.
To eliminate dependence on reference surfaces and translation stage guidance errors.
To identify and mitigate sources of periodic and curvature errors in reconstructed profiles.

Main Methods:

Analysis of information content in displaced sub-aperture measurements.
Theoretical modeling of error propagation during stitching.
Computer simulations and experimental validation using two distinct metrology instruments.

Main Results:

Sufficient information for error-free profile reconstruction exists within displaced sub-aperture measurements.
Evenly spaced stitching must be avoided; pitch error or reference curvature must be measured.
Successful reconstruction of 1D profiles free of additive systematic errors was demonstrated.

Conclusions:

The proposed method enables accurate mirror profile reconstruction by addressing specific measurement conditions.
Understanding and compensating for linear stage pitch errors or reference curvature is crucial.
This approach offers a robust solution for high-accuracy surface metrology in optical manufacturing.
