Photography optics in the time dimension
WebThe essential elements of the image are usually established immediately at the time of exposure. This characteristic is unique to photography and sets it apart from other ways of picture making. The seemingly automatic recording of an image by photography has given the process a sense of authenticity shared by no other picture-making technique. WebToday the imaging optics of ultrafast cameras, time-of-flight cameras, and depth cameras are simply inherited from the conventional photography optics of low-speed cameras. …

Mil-C-48497, along with several other similar Mil-Specs, does dimension scratches for certain types of optics, mainly opaque optics. Customers using those dimensions will need to specifically call them out as letters.
