Looking through a Pinhole: Physical and Physiological Phenomena
نویسنده
چکیده
A rich phenomenology could be studied in the misfocused vision through a pinhole or a system of pinholes punched on a black cardboard. Some of the observations we describe here can be also found in the ancient Literature. In this paper, we aim to rediscover and discuss some particular effects in light of a new perspective which provide an answer to interesting zero-cost experiments. In particular, in this paper we explain a fringing effect from the early contemporary Literature through an alternative geometrical model.

Effects of Circadian Rhythm on Physical and physiological Performance of Military forces- Narrative Review
The 2017 Nobel Prize for medicine was awarded the biological clock Scientist, which shows the importance of this phenomenon in the life of living organisms. The circadian Rhythm (CR) through the created internal “clock” is responsible for regulating the daily performance of different organs of the body. The central body clock is the key factor to creating and maintaining this CR. External optic...
متن کاملSnake's perspective on heat: reconstruction of input using an imperfect detection system.
Two groups of snakes possess an infrared detection system that is used to create a heat image of their environment. In this Letter we present an explicit reconstruction model, the "virtual lens," which explains how a snake can overcome the optical limitations of a wide aperture pinhole camera, and how ensuing properties of the receptive fields on the infrared-sensitive membrane may explain the ...
متن کاملIntroduction to Schramm-Loewner evolution and its application to critical systems
In this short review we look at recent advances in Schramm-Loewner Evolution (SLE) theory and its application to critical phenomena. The application of SLE goes beyond critical systems to other time dependent, scale invariant phenomena such as turbulence, sand-piles and watersheds. Through the use of SLE, the evolution of conformally invariant paths on the complex plane can be followed; hence a...
متن کاملPinhole hologram and its applications.
We propose the use of a pinhole-camera approach to make holograms. On recording the object beam passes through a pinhole, forming an image plane hologram, but on reconstruction the pinhole can be taken away. The reconstructed image can be programmed and processed by using optical information-processing elements placed in the position of the reconstructed pinhole or pinholes. Pinhole holography ...
متن کاملProposed new signal for real-time stress monitoring: Combination of physiological measures
Human stress is a physiological tension that appears when a person responds to mental, emotional, or physical chal-lenges. Detecting human stress and developing methods to manage it, has become an important issue nowadays. Au-tomatic stress detection through physiological signals may be a useful method for solving this problem. In most of the earlier studies, long-term time window was considere...
