The term "beat length" is correct and usable in written English.
It is a music-related term that describes the length of a single cycle, or beat, of a regular rhythmic pattern (as opposed to the tempo, which is the speed at which the pattern is played). For example, a drumbeat may have a beat length of four measures.
Environment temperature and operating wavelength may influence the beat length of the birefringence fiber, inducing the instability of fiber wave plates on polarization transforming.
The second-order analysis shows a resonant behavior which is related to the ratio of the plate length to the second beat length.
Variation of different optical properties of the fiber such as effective refractive index, birefringence, beat length, confinement loss, effective mode area, dispersion and nonlinear coefficient are studied.
The device length was significantly reduced by adopting the restricted multimode interference scheme, lower beat length ratio and cascaded MMI couplers.
The designed fibre shows various optical properties such as dispersion, birefringence, beat length and loss with respect to wavelength and compared with different filling factor like 0.1, 0.3 and 0.5.
As for the variable-spun fiber wave plate with different structure parameters (fiber length, spun rate profile and maximum spun rate), this paper firstly focuses on the influence of beat length on its equivalent phase retardation.
The drums and flute are, in fact, playing named stereotyped patterns normally of eight-beat length as in the Noh.
In the koto solo instrumental music (shirabemono), the most important type is the danmono, a variation piece in several sections (dan), each normally of 104-beat length.
After hatching, the heart beat and length of larvae were determined.
In-vehicle PM2.5 was positively associated with ectopic beats, heart beat cycle length, HF HRV, and SDNN.
In this special issue, M. D. Zink et al. investigated whether heart beat cycle length measurement assessed by a novel algorithm for a ballistocardiography (BCG) foil is feasible during sinus rhythm and AF.
