The term for enhancing image clarity is "image enhancement." This process involves improving the visual quality of an image by making it sharper, adjusting contrast, brightness, or reducing noise. Techniques like sharpening filters, contrast adjustments, and noise reduction are commonly used for image enhancement.

A circular polarizer enhances the quality of photographs by reducing glare and reflections, increasing color saturation, and improving contrast in the image.
Easiest and non-destructive (means you can change settings at any time after applying them even after saving and reopening image) way is to use Brightness/Contrast adjustments from Adjustments panel (Window > Adjustments) or go to Layer > New Adjustments Layer > Brightness/Contrast.

Adjusting the diaphragm on a microscope controls the amount of light passing through the specimen. By adjusting the diaphragm, you can improve the contrast and clarity of the image. It also helps in reducing glare and improving the overall quality of the microscopy image.
Image restoration means improving the image to match the original image. Image enhancement means improving the image to show some "hidden" details / bringing into evidence some part of the image. It only applies locally and is not necessarily constrained to match the original real image.
Contrast in microscopy refers to the ability to distinguish between an object and its background. It is achieved by using various techniques such as staining, phase contrast, or differential interference contrast to enhance the visibility and definition of the specimen being observed under the microscope. These methods help provide better image quality and allow for more detailed observation of biological samples.
