    • Disclosed herein is a method of examining tissue growth and/or conditioning and/or adhesion properties of cells on a synthetic and/or natural scaffold (30) as well as a perfusion bioreactor (10) for use in this method. The method comprises the following steps: fixing a scaffold (30) to a holding means (28) disposed or disposable in a perfusion bioreactor (10), generating a flow of nutrition solution along the surface of said scaffold (30) held by said holding means (28), generating and/or maintaining physiological conditions in said nutrition solution flowing along said scaffold (30) using heat exchange means (20, 24, 48, 50) and/or gas exchange means (52, 54, 56, 58, 60, 62, 64) associated with said bioreactor (10), such as to allow growth and/or conditioning of cells on said scaffold (30), and optically inspecting, in particular by microscopy, the scaffold (30) held by said holding means (28) through a window (66, 68, 70, 72) provided in said perfusion bioreactor (10) at different times or continuously during tissue growth and/or conditioning of cells on said scaffold (30) while maintaining said physiological conditions in said perfusion bioreactor (10).

    • In at least one embodiment, the wavelength-tunable light source (1) comprises an output source (2) suitable for generating an electromagnetic beam (R) during operation. The light source (1) further comprises a wavelength-selective first filter element (5) disposed downstream of the output source (2). The light source (1) also comprises a first amplifier medium (3) disposed downstream of the first filter element (5) and suitable for at least partially amplifying the beam (R) emitted by the output source (2). The light source (1) further comprises at least one wavelength-selective second filter element (6) disposed downstream of the first amplifier medium (3), wherein the second filter element (6) has an optical distance (L) to the first filter element (5). The first (5) and the at least one second filter element (6) can be tuned using a control unit (11) that comprises the light source (1). In the process, the filter elements (5, 6) are tuned such that the first (5) and the second filter element (6) are transparent for part (P) of the beam (R) in a time delay (T) relative to one another, wherein the delay (T) is equal to the quotient of the optical distance (L) and the speed of light in a vacuum (c).
    • 在波长可调光源(1)的至少一个实施例中,这包括适合于产生电磁辐射(R)的操作期间的输出源(2)。 此外,光源(1)具有布置在输出源(2)下游的波长选择性第一滤波器元件(5)。 此外,该光源(1)包括:第一放大介质(3),该第一过滤器元件(5)的下游和至少到输出的从所述源(2)辐射(R)是合适的局部增益发射。 所述光源(1)还包括至少一个波长选择第二过滤器元件(6),其在第一放大介质的下游侧(3),其中,所述第二过滤器元件(6)连接到第一过滤器元件(5)的光学距离(L)。 经由具有光源(1)的控制单元(11),第一(5)和至少一个第二过滤器元件(6)是可调的。 过滤器元件(5,6)在这种情况下调整,使得所述第一(5)和第二过滤器元件(6)的辐射(R)中的时间延迟(T)的部分光束(P)是可渗透到彼此,其中所述延迟(T )等于光学距离(L)和真空光速(c)的商。
