CALCULATORS / OPTICS AND ACOUSTICS

Optics, imaging and illumination

Paraxial geometry or calibrated radiometric/photometric models.

sensor size, focal length, working distance → angular and linear field of view

target field, sensor, lens model → working distance, magnification

field of view, pixel count, optical assumptions → length per pixel, feature sampling

focal length, aperture, focus distance, circle criterion → near/far limits, usable depth

focal length, object or image distance → image distance, magnification

baseline, focal length in pixels, disparity and error → depth, depth uncertainty

baseline, beam and camera geometry, feature error → range, sensitivity, blind regions

intensity distribution, distance, angle, transmission → illuminance, coverage

source power, beam geometry, transmission, receiver area → incident power, power density

spectrum, radiant quantities, photopic weighting → luminous flux/intensity, stated spectral dependence

wavelength, aperture, focal length → Airy size, nominal resolution

indices, input angular distribution, path geometry → critical angle, geometric acceptance
