After being adjusted for the working distance, the subject's retina is conjugate with optical infinity (Fig 2-2C). ) Another example of conjugacy is demonstrated by direct ophthalmoscopy. After being compensated for the refractive errors of the eyes of the examiner and subject by dialing an appropriate working lens into the ophthalmoscope, the 2 retinas are conjugate (Fig 2-3). Because light entering the subject's eye is intense and distracting, and little light illuminates the inside of the examiner's eye, the subject cannot see the examiner's retina.
Not to scale. The inset (Illustration developed by Kevin M. Clark.! 4 mm, Axial magnification, also known as longitudinal magnification, is measured along the optical axis, For small distances around the image plane, axial magnification is the square of the transverse magnification, Axial magnification = (transverse magnification)2 Angular magnification is the ratio of the angle subtended by an object at the eye using a lens or magnifier divided by the angle subtended by the object without the lens or magnifier.
This process serves as a very efficient mechanism for collimating light. In a typical laser, the beam increases by about I mm in diameter for every meter traveled. Directionality makes it easy to collect all of the light energy in a simple lens system and focus this light to a small spot. Coherence Coherence, meaning that all the propagated energy from the source is in phase, is the term most often associated with lasers (see Fig 1-5 and the earlier discussion, Interference and Coherence). Laser light projected onto a rough surface produces a characteristic sparkling quality known as laser speckle.
