We cannot get such image using a concave lens because the concave lens always produces the diminished image. So this is a convex lens. Images through lenses as real, virtual, erect or magnified The figure shows the virtual image formed by the convex lens and real image formed by a concave...
Whether enlarged or not, the image, formed at a point such as 14, will be reflected into the concave mirror 6 and may be viewed by an observer along such a line as that indicated at 13, the observer's eye being necessarily at a position such as 12. The amount of magnification will ...
The term “holographic silver halide photosensitive materials” as used in the invention refers to the silver halide photosensitive materials in which interference waves formed between object light and reference light can be recorded. In this wavefront recording, both amplitude and phase of the object...
12341. [Class 97 (i)] [Also in Group XL] In a combination for projecting images, comprising a cathode-ray tube, a concave mirror, and an aspherical plate or system correcting spherical aberration of the mirror, the mirror is formed on a part of the envelope of the tube or is disposed...
In addition, it is advantageous that the reference beams are collimated beams, so a concave mirror (7) is used to advantage. The invention provides a system for taking portraits in accordance with holography, wherein reflection holograms are recorded at two different wavelength in a sheet of ...
