The phase contrast transfer function is a function of limiting apertures and aberrations in the imaging lenses of a microscope. It describes their effect on the phase of the exit wave φ e ( x , u ) and propagates it to the image wave.
The Advanced Light Source (ALS) in Berkeley, California, is home to XM-1, a full-field soft X-ray microscope operated by the Center for X-ray Optics and dedicated to various applications in modern nanoscience, such as nanomagnetic materials, environmental and materials sciences and biology.
By virtue of the linearity property of optical non-coherent imaging systems, i.e., . Image(Object 1 + Object 2) = Image(Object 1) + Image(Object 2). the image of an object in a microscope or telescope as a non-coherent imaging system can be computed by expressing the object-plane field as a weighted sum of 2D impulse functions, and then expressing the image plane field as a weighted sum of the ...
The secretariat of an international organization is the department that fulfils its central administrative or general secretary duties. The term is especially associated with governments and intergovernmental organizations such as the United Nations, although some non-governmental organizations (for example, the International Organization for Standardization [1] [2]) also refer to their ...
Cells in rat anterior pituitary gland which contain large quantities of the enzyme glutamine synthetase also express the S100 protein which is the marker for folliculostellate cells. After exogenous glucocorticoid administration, the number of these cells increases and the activity of glutamine synthetase also increases. [1]
