Photodetectors, also called photosensors, are devices that detect light or other forms of electromagnetic radiation and convert it into an electrical signal. They are essential in a wide range of applications, from digital imaging and optical communication to scientific research and industrial automation. Photodetectors can be classified by their mechanism of detection, such as the photoelectric effect, photochemical reactions, or thermal effects, or by performance metrics like spectral response. Common types include photodiodes, phototransistors, and photomultiplier tubes, each suited to specific uses. Solar cells, which convert light into electricity, are also a type of photodetector. This article explores the principles behind photodetectors, their various types, applications, and recent advancements in the field.

Myst is a 1993 adventure video game developed by Cyan and published by Broderbund for Mac OS. In the game, the player travels via a special book to a mysterious island called Myst. The player interacts with objects and traverses the environment by clicking on pre-rendered imagery. Solving puzzles allows the player to travel to other worlds ("Ages"), which reveal the backstory of the game's characters and help the player make the choice of whom to aid.

Designers Rand and Robyn Miller had started in game development creating black-and-white, largely plotless works aimed at children. They wanted Myst to be a graphically impressive game with a nonlinear story and mystery elements aimed at adults. The game's design was limited by the small memory footprint of video game consoles and by the slow speed of CD-ROM drives. The game was created on Apple Macintosh computers and ran on the HyperCard software stack, though ports to other platforms subsequently required the creation of a new engine.
