👉 A hodoscope is a type of optical instrument that uses dichroic mirrors to focus light into an image. It is commonly used in medical imaging, such as X-rays and ultrasound, where it helps to enhance the resolution and quality of the images. Hodoscopes are typically made up of multiple layers of glass, metal, and other materials to provide different degrees of diffraction, allowing for a wider range of wavelengths to be focused into an image.
