大家应该知道一个镜头的中心比边缘成像能力要好很多因此只测试镜头的中心或边缘是不能代表镜头的好坏的所以厂家会从中心到边缘选取多个点进行测试。如下图尼康的全画幅机器选取了距离中心5毫米10mm15mm20mm的点测试。如果是APS-C画幅因为感光元件小会选取3mm6mm9mm12mm等不同厂家可能不一样。

title: Q factor

# Explanation
In physics and engineering, the quality factor or Q factor is a **dimensionless** parameter that describes how **underdamped** an oscillator or *resonator* is. It is defined as the ratio of the initial energy stored in the resonator to the *energy lost* in one radian of the cycle of oscillation. Q factor is alternatively defined as the ratio of a *resonator's center frequency to its bandwidth* when subject to an oscillating driving force. These two definitions give *numerically similar*, but not identical, results.

Q因子较高的振子在共振时在共振频率附近的**振幅较大**,但会产生的共振的**频率范围比较小**,此频率范围可以称为频宽。
例如一台无线电接收器内的调谐电路Q因子较高要调整接收器对准一特定频率会比较困难但其选择性较好在过滤频谱上邻近电台的讯号上也有较佳的效果。
系统的Q因子可能会随著应用场合及需求的不同而有大幅的差异。*强调阻尼特性的系统*(例如[防止门突然关闭的阻尼器](warehouse/dampers_keeping_a_door_from_slamming%20shut.md)*其Q因子为12*而时钟、雷射或是其他需要强烈共振或是要求频率稳定性的系统其Q因子也较高。音叉的Q因子大约为1000原子钟、加速器中的超导射频或是光学共振腔的Q因子可以到$10^{11}$

> There are many *alternative quantities* used by physicists and engineers to describe how damped an oscillator is. Important examples include: the [damping ratio](https://en.wikipedia.org/wiki/Damping_ratio "Damping ratio"), [relative bandwidth](https://en.wikipedia.org/wiki/Bandwidth_(signal_processing) "Bandwidth (signal processing)"), [linewidth](https://en.wikipedia.org/wiki/Oscillator_linewidth "Oscillator linewidth") and bandwidth measured in [octaves](https://en.wikipedia.org/wiki/Octave_(electronics) "Octave (electronics)").
# Definition

<font size=1>Fig. 一阻尼谐振子的频宽, $\Delta f$可以用频率和能量的图来表示。阻尼谐振子或滤波器的Q因子为$f_{0}/\Delta f$。Q因子越大其波峰高度会越高而其宽度会越窄</font>
In the context of resonators, there are two common definitions for Q, which aren't exactly equivalent. They become approximately equivalent *as Q becomes larger*, meaning the resonator becomes less damped.
## Bandwidth definition
$$Q\stackrel{def}{=}\frac{f_r}{\Delta f}=\frac{\omega_r}{\Delta \omega}$$
$f_r$为共振频率,$\Delta f$为频宽,一般是 [full width at half maximum](https://en.wikipedia.org/wiki/Full_width_at_half_maximum "Full width at half maximum") (FWHM)
## Stored energy definition
Q因子可定义为在一系统的共振频率下当信号振幅不随时间变化时**系统储存能量和每个周期外界所提供能量的比例**(此时系统储存能量也不随时间变化)
$$Q = 2\pi \times \frac{\text{Energy Stored}}{\text{Energy dissipated per cycle}}=2\pi f_r \times \frac{\text{Energy Stored}}{\text{Power Loss}}$$
同时在像电感等储能元件的规格中会用到和频率有关的Q因子其定义如下
$$Q(\omega) = \omega \times \frac{\text{Maximum Energy Stored}}{\text{Power Loss}}$$
其中$\omega$是计算储存能量和功率损失时的角频率

要解释像差如何使图像模糊,首先要解释一下:什么是混淆圈? 当来自目标的光点到达镜头,然后会聚在传感器上时,它会很清晰。 否则,如果它在传感器之前或之后会聚,则传感器上的光分布会更广。 这可以在图 1 中看到,其中可以看到点光源会聚在传感器上,但随着传感器位置的变化,沿传感器散布的光量也会发生变化。

光线越分散,图像的焦点就越少。 除非光圈很小,否则图像中彼此距离较大的目标通常会使背景或前景失焦。 这是因为会聚在前景中的光与来自背景中较远目标的光会聚在不同的点。

光的颜色代表特定波长的光。 由于折射,彩色图像将有多个波长进入镜头并聚焦在不同的点。 纵向或轴向色差是由不同波长聚焦在沿光轴的不同点引起的。 波长越短,其焦点将离镜头越近,而波长越远,则反之,离镜头越远,如图 8 所示。通过引入较小的孔径,进入的光仍可能聚焦在不同的位置 点,但“混淆圈”的宽度(直径)会小得多,导致不那么剧烈的模糊。

它可以使用引入不同折射率的消色差双合透镜来固定。 通过将可见光谱的两端置于一个焦点上,可以消除色边。 对于横向和纵向色差,减小光圈的大小也有帮助。 此外,在高对比度环境(即具有非常亮的背景的图像)中不成像目标可能是有益的。 在显微镜中,镜头可能使用复消色差透镜 (APO) 而不是消色差透镜,消色差透镜使用三个透镜元件来校正入射光的所有波长。 当颜色最重要时,确保减轻色差将产生最佳效果。

多普勒效应(**Doppler effect**)是波源和观察者有相对运动时,观察者接受到波的频率与波源发出的频率并不相同的现象。
远方急驶过来的火车鸣笛声变得尖细(即频率变高,波长变短),而离我们而去的火车鸣笛声变得低沉(即频率变低,波长变长),就是多普勒效应的现象,同样现象也发生在汽车鸣响与火车的敲钟声。
# General
在classical physics中source的speed和receiver的speed远小于wave在medium中的移动速度observed frequency $f$和emitted frequency$f_0$关系:
$$
f = (\frac{c \pm v_r}{c \pm v_s})f_0
$$
* $c$是wave在介质中的速度
* $v_r$是receiver相对于介质的速度如果receiver向source移动则分子为加号反之为减号
* $v_s$是source相对于介质的速度如果source远离receiver则分母为加号反之为减号
> [!note]
> 请注意,此关系预测如果源或接收器中的任何一个远离另一个,频率将会降低。
$$
\frac{f}{v_{wr}} = \frac{f_0}{v_{ws}} = \frac{1}{\lambda}
$$
* $v_{\omega r}$是wave speed相对于receiver
* $v_{\omega s}$是wave speed相对于source
* $\lambda$是波长
## Example
![](physics/Wave/attachments/Dopplereffectsourcemovingrightatmach0.7.gif)
其中$v_s = 0.7c$,波前开始在源的右侧(前面)聚集,并在源的左侧(后面)进一步分开。
在前面的receiver会听到higher frequency也就是$f = \frac{c}{c-0.7c}f_0 = 3.33f_0$后面的receiver会听到lower frequency也就是$f = \frac{c}{c + 0.7c}f_0 = 0.59f_0$

大家应该知道一个镜头的中心比边缘成像能力要好很多因此只测试镜头的中心或边缘是不能代表镜头的好坏的所以厂家会从中心到边缘选取多个点进行测试。如下图尼康的全画幅机器选取了距离中心5毫米10mm15mm20mm的点测试。如果是APS-C画幅因为感光元件小会选取3mm6mm9mm12mm等不同厂家可能不一样。

# Hiking
周五,周潭来杭,计划去蛤蟆峰顶拍拍立得慢门,记录西湖夜景。
晚饭后,雨渐起,兴致不减,亦去。
山底已经在小雨中颇有丁达尔现象的感觉。
![](photography/Story/attachments/9970714720C0835E6547C263418D551B.jpg)
雨让石头逐渐变得打滑,蛤蟆峰山顶的石头快的攀登会变得非常危险,这一点难以描述,或许你可以问你杭州本地的朋友。周潭在攀登最后一段路程之前摔倒,还好背包缓冲了几乎所有的冲撞,也让他意识到雨天来到这里的危险性,是具有极限运动的底色在的。
最后,在小心翼翼中,登顶了。
# Photographer
在蛤蟆峰顶拍慢门需要一定的三脚架架设技巧和测光技巧,在雨中就显得更加困难。

![](photography/Story/attachments/FCB8B96468D3B459532E010E865D0B99.jpg)
经过测光和宝丽来app曝光调整这次拍摄夜景的计划以$f/22$, 30s shutter speed, i-type film 640 ISO进行拍摄先看成片效果
![](photography/Story/attachments/IMG_5553.jpg)
照片由iPhone 12 mini Polaroid app scanner扫描完成的film -> digital效果比较一般但我们能看出曝光的效果不尽人意。这里的原因认为由以下原因导致
* 天气恶劣,空气湿度大,造成光线色散加重
* 没有考虑i-type相纸**倒易率**,曝光时间不足(重要原因🚧🚧🚧)
* 没有查询Polaroid now+镜头最好的光学素质的参数,自认为是$f/22$导致曝光时间过长导致的点光源色散严重。目前还没有查询到Polaroid now+镜头的光学参数曲线🚧🚧🚧)
同时那晚还不懂now+ +键的使用导致相纸浪费一张下面是now+中+键的用法:
![](photography/Story/attachments/Pasted%20image%2020230416014050.png)
同时,那晚曝光时,有一次光圈不小心打到$f/33$,导致欠曝地更为厉害,其效果大概如下:
![](photography/Story/attachments/IMG_5550.jpg)
同时要注意的是Polaroid的曝光时间最多是30s如果要更长时间的曝光可以不弹相纸进行二次曝光但是长曝光30s以上可能效果很差。
## 人像
搞了两张人像,同样的曝光参数$f/22$, 30s shutter speed, i-type film 640 ISO开了宝丽来闪关灯最大等级
![](photography/Story/attachments/IMG_5492.jpg)
![](photography/Story/attachments/IMG_5493.jpg)
第一张人像清晰些,以我个人观点来看,是因为伞造成的反射
# 返程
返程的故事有趣了些,因为三脚架落在了山脚,于是返回去取,但是去取的时候手机落在了打的网约车上。
因为手机丢了,所以无法确认订单的详细信息,也就无法联系司机和客服。
所以用周潭的手机去登录高德打车去确认订单但是登录高德又需要手机验证码非常傻逼的设计就是了还好带了apple watch连接了周潭的热点后可以同步手机消息收到验证码这才登上了高德地图。
高德地图的打车是联动多家打车公司的,所以情况错综复杂,我的订单来自天猫出行,高德端不允许我直接联系师傅,同时天猫出行的客服也无法拨通,最后还好拨通了高德客服的电话,联系上了师傅。
师傅当时前往了滨江,所以我们只好在山脚下,也就是保俶路的忠儿面馆那里等待,刚好周潭没有吃饱,起源巧合下,在这也算吃了一顿还算杭州特色的拌川。
