# Dictionary:Hankel transform

(hank’ ∂l) The Hankel transform of order ${\displaystyle m}$ of the real function ${\displaystyle f(t)}$ is
${\displaystyle F(s)=\int J_{m}(st)\;dt}$
where ${\displaystyle J_{m}}$ is the ${\displaystyle m}$-order Bessel function. Also called a Bessel transform. Named for Hermann Hankel (1839–1873), German mathematician.
